It is the equivalent of multi() but for Tapscript, using CHECKSIGADD
instead of CHECKMULTISIG.
It shares the same properties as multi() but for 'n', since a threshold
multi_a() may have an empty vector as the top element of its
satisfaction. It could also have the 'o' property when it only has a
single key, but in this case a 'pk()' is always preferable anyways.
We are going to introduce Tapscript support in Miniscript, for which
some of Miniscript rules and properties change (new or modified
fragments, different typing rules, different resources consumption, ..).

Permit (restricted topology) submitpackage RPC outside of regtest. Suggested in https://github.com/bitcoin/bitcoin/pull/26933#issuecomment-1510851570
This RPC should be safe but still experimental - interface may change, not all features (e.g. package RBF) are implemented, etc. If a miner wants to expose this to people, they can effectively use "package relay" before the p2p changes are implemented. However, please note **this is not package relay**; transactions submitted this way will not relay to other nodes if the feerates are below their mempool min fee. Users should put this behind some kind of rate limit or permissions.

c1e6c542af descriptors: disallow hybrid public keys (Pieter Wuille)
Pull request description:
Fixes #28511
The descriptor documentation (`doc/descriptors.md`) and [BIP380](https://github.com/bitcoin/bips/blob/master/bip-0380.mediawiki) explicitly require that hex-encoded public keys start with 02 or 03 (compressed) or 04 (uncompressed). However, the current parsing/inference code permit 06 and 07 (hybrid) encoding as well. Fix this.

`vfLimited`, `IsReachable()`, `SetReachable()` need not be in the `net`
module. Move them to `netbase` because they will be needed in
`LookupSubNet()` to possibly flip the result to CJDNS (if that network
is reachable).
In the process, encapsulate them in a class.
`NET_UNROUTABLE` and `NET_INTERNAL` are no longer ignored when adding
or removing reachable networks. This was unnecessary.
From https://geti2p.net/en/docs/api/samv3:
If SILENT=false was passed, which is the default value, the SAM bridge
sends the client a ASCII line containing the base64 public destination
key of the requesting peer
So, `Accept()` is supposed to receive a Base64 encoded destination of
the connecting peer, but if it receives something like this instead:
STREAM STATUS RESULT=I2P_ERROR MESSAGE="Session was closed"
then destroy the session.
The descriptor documentation (doc/descriptors.md) and BIP380 explicitly
require that hex-encoded public keys start with 02 or 03 (compressed) or
04 (uncompressed). However, the current parsing/inference code permit 06

352d5eb2a9 test: getrawaddrman RPC (0xb10c)
da384a286b rpc: getrawaddrman for addrman entries (0xb10c)
Pull request description:
Inspired by `getaddrmaninfo` (#27511), this adds a hidden/test-only `getrawaddrman` RPC. The RPC returns information on all addresses in the address manager new and tried tables. Addrman table contents can be used in tests and during development.
The RPC result encodes the `bucket` and `position`, the internal location of addresses in the tables, in the address object's string key. This allows users to choose to consume or to ignore the location information. If the internals of the address manager implementation change, the location encoding might change too.
```
getrawaddrman
EXPERIMENTAL warning: this call may be changed in future releases.
Returns information on all address manager entries for the new and tried tables.
Result:
{ (json object)
"table" : { (json object) buckets with addresses in the address manager table ( new, tried )
"bucket/position" : { (json object) the location in the address manager table (<bucket>/<position>)
"address" : "str", (string) The address of the node
"port" : n, (numeric) The port number of the node
"network" : "str", (string) The network (ipv4, ipv6, onion, i2p, cjdns) of the address
"services" : n, (numeric) The services offered by the node
"time" : xxx, (numeric) The UNIX epoch time when the node was last seen

Pull request description:
_This is a piece of #21878, chopped off to ease review._
Peeking at the underlying socket file descriptor of `Sock` and checkig if it is `INVALID_SOCKET` is bad encapsulation and stands in the way of testing/mocking/fuzzing.
Instead use an empty `unique_ptr` to denote that there is no valid socket where appropriate or outright remove such checks where they are not necessary.
The default constructor `Sock::Sock()` is unnecessary now after recent changes, thus remove it.

This changeset finishes the first phase of the assumeutxo project. It makes UTXO snapshots loadable via RPC (`loadtxoutset`) and adds `assumeutxo` parameters to chainparams. It contains all the remaining changes necessary to both use an assumedvalid snapshot chainstate and do a full validation sync in the background.
This may look like a lot to review, but note that
- ~200 lines are a (non-essential) demo shell script
- Many lines are functional test, documentation, and relatively dilute RPC code.
So it shouldn't be as burdensome to review as the linecount might suggest.
- **P2P**: minor changes are made to `init.cpp` and `net_processing.cpp` to make simultaneous IBD across multiple chainstates work.
- **Pruning**: implement correct pruning behavior when using a background chainstate
- **Blockfile separation**: to prevent "fragmentation" in blockfile storage, have background chainstates use separate blockfiles from active snapshot chainstates to avoid interleaving heights and impairing pruning.
- **Indexing**: some `CValidationInterface` events are given with an additional parameter, ChainstateRole, and all indexers ignore events from ChainstateRole::ASSUMEDVALID so that indexation only happens sequentially.
- Have `-reindex` properly wipe snapshot chainstates.
- **RPC**: introduce RPC commands `loadtxoutset` and (hidden) `getchainstates`.
- **Release docs & first assumeutxo commitment**: add notes and a particular assumeutxo hash value for first AU-enabled release.
- This will complete the project and allow use of UTXO snapshots for faster node bootstrap.
The next phase, if it were to be pursued, would be coming up with a way to distribute the UTXO snapshots over the P2P network.

### UTXO snapshots
Create your own with `./contrib/devtools/utxo_snapshot.sh`, e.g.
```shell
./contrib/devtools/utxo_snapshot.sh 788000 utxo.dat ./src/bitcoin-cli -datadir=$(pwd)/testdata`)
```
or use the pre-generated ones listed below.

### Testing
#### For fun (~5min)
If you want to do a quick test, you can run `./contrib/devtools/test_utxo_snapshots.sh` and follow the instructions. This is mostly obviated by the functional tests, though.
#### For real (longer)
If you'd like to experience a real usage of assumeutxo, you can do that too.
I've cut a new snapshot at height 788'000 (http://img.jameso.be/utxo-788000.dat - but you can do it yourself with `./contrib/devtools/utxo_snapshot.sh` if you want). Download that, and then create a datadir for testing:
```sh
$ cd ~/src/bitcoin # or whatever
# get the snapshot
$ curl http://img.jameso.be/utxo-788000.dat > utxo-788000.dat
# you'll want to do this if you like copy/pasting
$ export AU_DATADIR=/home/${USER}/au-test # or wherever
$ mkdir ${AU_DATADIR}
$ vim ${AU_DATADIR}/bitcoin.conf
dbcache=8000 # or, you know, something high
blockfilterindex=1
coinstatsindex=1
prune=3000
logthreadnames=1
```
Obtain this branch, build it, and then start bitcoind:
```sh
$ git remote add jamesob https://github.com/jamesob/bitcoin
$ git fetch jamesob assumeutxo
$ git checkout jamesob/assumeutxo
$ ./configure $conf_args && make # (whatever you like to do here)
# start 'er up and watch the logs
$ ./src/bitcoind -datadir=${AU_DATADIR}
```
Then, in some other window, load the snapshot
```sh
$ ./src/bitcoin-cli -datadir=${AU_DATADIR} loadtxoutset $(pwd)/utxo-788000.dat
```
You'll see some log messages about headers retrieval and waiting to see the snapshot in the headers chain. Once you get the full headers chain, you'll spend a decent amount of time (~10min) loading the snapshot, checking it, and flushing it to disk. After all that happens, you should be syncing to tip in pretty short order, and you'll see the occasional `[background validation]` log message go by.
In yet another window, you can check out chainstate status with
```sh
$ ./src/bitcoin-cli -datadir=${AU_DATADIR} getchainstates
```
as well as usual favorites like `getblockchaininfo`.

Exposing address manager table entries in a hidden RPC allows to introspect
addrman tables in tests and during development.
As response JSON object the following FORMAT1 is choosen:
{
"table": {
"<bucket>/<position>": { "address": "..", "port": .., ... },
"<bucket>/<position>": { "address": "..", "port": .., ... },
"<bucket>/<position>": { "address": "..", "port": .., ... },
...
}
}
An alternative would be FORMAT2
{
"table": {
"bucket": {
"position": { "address": "..", "port": .., ... },
"position": { "address": "..", "port": .., ... },
..
},
"bucket": {
"position": { "address": "..", "port": .., ... },
..
},
}
}
FORMAT1 and FORMAT2 have different encodings for the location of the
address in the address manager. While FORMAT2 might be easier to process
for downstream tools, it also mimics internal addrman mappings, which
might change at some point. Users not interested in the address location
can ignore the location key. They don't have to adapt to a new RPC
response format, when the internal addrman layout changes. Additionally,
FORMAT1 is also slightly easier to to iterate in downstream tools. The
RPC response-building implemenation complexcity is lower with FORMAT1
as we can more easily build a "<bucket>/<position>" key than a multiple
"bucket" objects with multiple "position" objects (FORMAT2).

Many edge cases exist when parents in a child-with-parents package can
spend each other. However, this pattern should also be uncommon in
normal use cases.
In future commits, loading the block index while making use of a
snapshot is contingent on the snapshot being recognized by chainparams.
Ensure all existing unittests that use snapshots use a recognized
snapshot (at height 110).
Co-authored-by: Ryan Ofsky <ryan@ofsky.org>
This allows us to reference assumeutxo configuration by blockhash as
well as height; this is helpful in future changes when we want to
reference assumeutxo configurations before the block index is loaded.

262ab8ef78 Add package evaluation fuzzer (Greg Sanders)
Pull request description:
This fuzzer target caught the issue in https://github.com/bitcoin/bitcoin/pull/28251 within 5 minutes on master branch, and an additional issue which I've applied a preliminary patch to cover.
Fuzzer target does the following:
1) Picks mempool confgs, including max package size, count, mempool size, etc
2) Generates 1 to 26 transactions with arbitrary coins/fees, the first N-1 spending only confirmed outpoints
3) Nth transaction, if >1, sweeps all unconfirmed outpoints in mempool
4) If N==1, it may submit it through single-tx submission path, to allow for more interesting topologies
5) Otherwise submits through package submission interface
6) Repeat 1-5 a few hundred times per mempool instance
In other words, it ends up building chains of txns in the mempool using parents-and-children packages, which is currently the topology supported on master.
The test itself is a direct rip of tx_pool.cpp, with a number of assertions removed because they were failing for unknown reasons, likely due to the notification changes of single tx submission to package, which is used to track addition/removal of transactions in the test. I'll continue working on re-adding these assertions for further invariant testing.

Pull request description:
Motivation
- I think it's preferable to use stdlib data structures instead of depending on boost if we can achieve the same thing.
- Also see #28335 for further context/motivation. This PR simplifies that one.
Things done in this PR:
- Add a bench for `DisconnectedBlockTransactions` where we reorg and the new chain has {100%, 90%, 10%} of the same transactions. AFAIU in practice, it's usually close to 100%.
- Rewrite `DisconnectedBlockTransactions` as a `std::list` + `unordered_map` instead of a boost multi index container.
- On my machine, the bench suggests the performance is very similar.
- Move `DisconnectedBlockTransactions` from txmempool.h to its own kernel/disconnected_transactions.h. This struct isn't used by txmempool and doesn't have much to do with txmempool. My guess is that it's been living there for convenience since the boost includes are there.

1) Replace MAX_PACKAGE_SIZE with MAX_PACKAGE_WEIGHT which accounts for additional WU necessary to not exclude default chain limit transactions that would have been accepted individually. Avoids sigops vbyte confusion.
2) pass correct vsize to chain limit evaluations in package context
3) stop overly-large packages that have no existing mempool ancestors (also a bugfix by itself if someone sets non-standard chain limits)
This should fix the known issues while not blocking additional refactoring later.

28bac81a34 test: add functional test for getaddrmaninfo (stratospher)
c8eb8dae51 rpc: Introduce getaddrmaninfo for count of addresses stored in new/tried table (stratospher)
Pull request description:
implements https://github.com/bitcoin/bitcoin/issues/26907. split off from #26988 to keep RPC, CLI discussions separate.
This PR introduces a new RPC `getaddrmaninfo`which returns the count of addresses in the new/tried table of a node's addrman broken down by network type. This would be useful for users who want to see the distribution of addresses from different networks across new/tried table in the addrman.
```jsx
$ getaddrmaninfo
Result:
{ (json object) json object with network type as keys
"network" : { (json object) The network (ipv4, ipv6, onion, i2p, cjdns)
"new" : n, (numeric) number of addresses in new table
"tried" : n, (numeric) number of addresses in tried table
"total" : n (numeric) total number of addresses in both new/tried tables from a network
},
...
}
```
### additional context from [original PR](https://github.com/bitcoin/bitcoin/pull/26988)
1. network coverage tests were skipped because there’s a small chance that addresses from different networks could hash to the same bucket and cause count of different network addresses in the tests to fail. see https://github.com/bitcoin/bitcoin/pull/26988#discussion_r1137596851.
2. #26988 uses this RPC in -addrinfo CLI. Slight preference for keeping the RPC hidden since this info will mostly be useful to only super users. see https://github.com/bitcoin/bitcoin/pull/26988#discussion_r1173964808.

While allowing submitted packages to be slightly larger than what
may be allowed in the mempool to allow simpler reasoning
about contextual-less checks vs chain limits.

ad0c469d98 wallet: Use CTxDestination in CRecipient rather than scriptPubKey (Andrew Chow)
07d3bdf4eb Add PubKeyDestination for P2PK scripts (Andrew Chow)
1a98a51c66 Allow CNoDestination to represent a raw script (Andrew Chow)
8dd067088d Make WitnessUnknown members private (Andrew Chow)
Pull request description:
For silent payments, we want to provide a `SilentPaymentsDestination` to be used as the recipient, which requires `CRecipient` to use something other than just the `scriptPubKey` as we cannot know the output script for a silent payment prior to transaction creation. `CTxDestination` seems like the obvious place to add a `SilentPaymentsDestination` as it is our internal representation of an address.
In order to still allow paying to arbitrary scriptPubKeys (e.g. for data carrier outputs, or the user hand crafted a raw transaction that they have given to `fundrawtransaction`), `CNoDestination` is changed to contain raw scripts.
Additionally, P2PK scripts are now interpreted as a new `PubKeyDestination` rather than `PKHash`. This results in some things that would have given an address for P2PK scripts to no longer do so. This is arguably more correct.
`ExtractDestination`'s behavior is slightly changed for the above. It now returns `true` for those destinations that have addresses, so P2PK scripts now result in `false`. Even though it returns false for `CNoDestination`, the script will now be included in that `CNoDestination`.

The type is only ever set, but never read via GetType(), so remove it.
Also, remove SerializeHash to avoid silent merge conflicts and use the
already existing GetHash() boilerplate consistently.
3f4e1bb9ae tests: fix incorrect assumption in v2transport_test (Pieter Wuille)
Pull request description:
One part of the current `v2transport_test` introduced in #28196 assumes that if a bit gets modified in a message, failure should instantly be detected after sending that message. This is not correct in case the length descriptor is modified, as that may cause the receiver to need more data first. Fix this by sending more messages until failure actually occurs.

This was only explicitly used in the tests, where it can be replaced by
wrapping the original raw file pointer into a CAutoFile on creation and
then calling CAutoFile::fclose().
Also, it was used in LoadExternalBlockFile(), where it can also be
replaced by the (implicit call to the) CAutoFile destructor after
wrapping the original raw file pointer in a CAutoFile.
