57ce20307e fuzz: allow lower number of sources (Martin Zumsande)
acf656d540 fuzz: Use public interface to fill addrman tried tables (Martin Zumsande)
eb2e113df1 addrman: Improve performance of Good (Martin Zumsande)
Pull request description:
Currently, `CAddrman::Good()` is rather slow because the process of moving an addr from new to tried involves looping over the new tables twice:
1) In `Good_()`, there is a loop searching for a new bucket the addr is currently in, but this information is never used except for aborting if it is not found anywhere (since [this commit](e6b343d880 (diff-49d1faa58beca1ee1509a247e0331bb91f8604e30a483a7b2dea813e6cea02e2R263)) it is no longer passed to `MakeTried`)
This is unnecessary because in a non-corrupted addrman, an address that is not in New must be either in Tried or not at all in addrman, both cases in which we'd return early in `Good_()` and never get to this point.
I removed this loop (and left a check for `nRefCount` as a belt-and-suspenders check).
2) In `MakeTried()`, which is called from `Good_()`, another loop removes all instances of this address from new. This can be spedup by stopping the search at `nRefCount==0`. Further reductions in `nRefCount` would only lead to an assert anyway.
Moreover, the search can be started at the bucket determined by the source of the addr for which `Good` was called, so that if it is present just once in New, no further buckets need to be checked.
While calls to `Good()` are not that frequent normally, the performance gain is clearly seen in the fuzz target `addman_serdeser`, where, because of the slowness in creating a decently filled addrman, a shortcut was created that would directly populate the tried tables by reaching into addrman's internals, bypassing `Good()` (#21129).
I removed this workaround in the second commit: Using `Good()` is still slower by a factor of 2 (down from a factor of ~60 before), but I think that this compensated by the advantages of not having to reach into the internal structures of addrman (see https://github.com/jnewbery/bitcoin/pull/18#issuecomment-775218676).
[Edit]: For benchmark results see https://github.com/bitcoin/bitcoin/pull/22974#issuecomment-919435266 and https://github.com/bitcoin/bitcoin/pull/22974#issuecomment-920445700 - the benchmark `AddrManGood` shows a significant speedup by a factor >100.

330d3aa1a2 refactor: net: avoid duplicate map lookups to `mapLocalHost` (Sebastian Falbesoner)
Pull request description:
This simple refactoring PR aims to avoid duplicate lookups to `mapLocalHost`: instead of calling `count()` (to first find out whether a key is in the map) and then `operator[]` (to get the value to the passed key, or default-construct one if not found), use either
* `find()` and dereference the returned iterator (for simple lookups), see https://www.cplusplus.com/reference/map/map/find/
* `emplace()` and use the returned <iterator, inserted> pair (for lookups where a new element should be inserted if the key isn't found), see https://www.cplusplus.com/reference/map/map/emplace/

65ed198295 wallet: refactor: inline function ReadOrderPos() (Sebastian Falbesoner)
Pull request description:
The functions `ReadOrderPos` and `WriteOrderPos` have been introduced in commit 9c7722b7c5 in 2012. Since accounts have been removed in #13825 (commit c9c32e6b84), they are only called at one place in `CWalletTx::{Serialize,Unserialize}` and thus can be directly inlined instead. Additionally, this PR aims to avoids duplicate lookups on the map `mapValue` (affects keys "n" and "timesmart").

350e034e64 consensus: don't call GetBlockPos in ReadBlockFromDisk without lock (Jon Atack)
Pull request description:
Commit ccd8ef65 "Reduce cs_main lock in ReadBlockFromDisk, only read GetBlockPos under the lock" in #11281 moved the cs_main lock from caller to `ReadBlockFromDisk()` for calling `CBlockIndex::GetBlockPos()`, but the second invocation doesn't have the lock, and IIUC there is no guarantee the compiler can know if state has changed.
Use the `blockPos` local variable instead, rename it to `block_pos`, and make it const.

e4709c7b56 Start using init makeNode, makeChain, etc methods (Russell Yanofsky)
Pull request description:
Use `interfaces::Init::make*` methods instead of `interfaces::Make*` functions, so interfaces can be constructed differently in different executable without having to change any code. (So for example `bitcoin-gui` can make an `interfaces::Node` pointer that communicates with a `bitcoin-node` subprocess, while `bitcoin-qt` can make an `interfaces::Node` pointer that controls node code in the same process.)

This is done by removing an unnecessary loop in Good_() and looping
through the new tables in MakeTried() more efficiently, choosing a
starting value that allow us to stop early in typical cases.

Adjust CheckBlockIndex to account for
- assumed-valid block indexes lacking transaction data, and
- setBlockIndexCandidates for the background chainstate not containing certain entries
which rely on assumed-valid ancestors.
Mark the block index entries that are beneath the snapshot base block as
assumed-valid. Subsequent commits will make use of this flag in other
parts of the system.
Instead of (ab)using the existing BLOCK_VALID_* flags to mark CBlockIndex entries which
we haven't yet fully validated (but assume validity for use with UTXO snapshot
loading), introduce a status flag that specifically marks an assumed-valid state.
This state is then removed in RaiseValidity() when the block has actually been
validated.
This distinction will allow us to make the necessary changes to various parts of the
system to facilitate assumeutxo/background chainstate validation but without leaking
details like snapshot height, as we had done previously.
Changes that actually make use of this flag follow in future commits.
Only perform certain behavior (namely that related to servicing
the getblocktemplate RPC call) for the active chainstate when
calling UpdateTip.
