703b1e612a Close minor startup race between main and scheduler threads (Larry Ruane)
Pull request description:
This is a low-priority bug fix. The scheduler thread runs `CheckForStaleTipAndEvictPeers()` every 45 seconds (EXTRA_PEER_CHECK_INTERVAL). If its first run happens before the active chain is set up (`CChain::SetTip()`), `bitcoind` will assert:
```
(...)
2021-07-28T22:16:49Z init message: Loading block index…
bitcoind: validation.cpp:4968: CChainState& ChainstateManager::ActiveChainstate() const: Assertion `m_active_chainstate' failed.
Aborted (core dumped)
```
I ran into this while using the debugger to investigate an unrelated problem. Single-stepping through threads with a debugger can cause the relative thread execution timing to be very different than usual. I don't think any automated tests are needed for this PR. I'll give reproduction steps in the next PR comment.

222290f543 test: Set BIP34Height = 2 for regtest (MarcoFalke)
fac90c55be test: Create all blocks with version 4 or higher (MarcoFalke)
Pull request description:
BIP34 is active on the current tip of mainnet, so all miners must obey it. It would be nice if it also was active in fresh regtest instances from the earliest time possible.
I changed the BIP34 height to `2`, so that the block at height=1 may be used to mine a duplicate coinbase. (Needed to test mainnet behaviour)
This pull is done in two commits:
* test: Create all blocks with version 4 or higher:
Now that BIP34 is activated earlier, we need to create blocks with a higher version number. Just bump it to 4 instead of 2 to avoid having to bump it again later.
* test: Set BIP34Height = 2 for regtest:
This fixes the BIP34 implementation in the tests (to match the one of the Core codebase) and updates the tests where needed

Don't schedule class PeerManagerImpl's background tasks from its
constructor, but instead do that from a separate method,
StartScheduledTasks(), that can be called later at the end of startup,
after other things, such as the active chain, are initialzed.
Leaving the incorrect indentation would be frustrating because:
* Some editor may fix up the whitespace when editing a file, so before
commiting the whitespace changes need to be undone.
* It makes it harder to use clang-format-diff on a change.
Can be trivially reviewed with --word-diff-regex=. --ignore-all-space

fa621ededd refactor: Pass script verify flags as uint32_t (MarcoFalke)
Pull request description:
The flags are cast to unsigned in the interpreter anyway, so avoid the confusion (and fuzz crashes) by just passing them as unsigned from the beginning.
Also, the flags are often inverted bit-wise with the `~` operator, which also works on signed integers, but might cause confusion as the sign bit is flipped.

a2aca207b1 Move implementations of non-template fuzz helpers (Sriram)
Pull request description:
There are 78 cpp files that include `util.h` (`grep -iIr "#include <test/fuzz/util.h>" src/test/fuzz | wc -l`). Modifying the implementation of a fuzz helper in `src/test/fuzz/util.h` will cause all fuzz tests to be recompiled. Keeping the declarations of these non-template fuzz helpers in `util.h` and moving their implementations to `util.cpp` will skip the redundant recompilation of all the fuzz tests, and builds these helpers only once in `util.cpp`.
Functions moved from `util.h` to `util.cpp`:
- `ConsumeTxMemPoolEntry`
- `ContainsSpentInput`
- `ConsumeNetAddr`
- Methods of `FuzzedFileProvider::(open, read, write, seek, close)`

After feedback from Russ, I realized that there are some extraneous assumeutxo methods
that are not necessary and probably just overly confusing. These include
- `Validated*()`
- `IsBackgroundIBD()`
and they can be removed.
Add an upwards reference to chainstate instances to the owning
ChainstateManager. This is necessary because there are a number
of `this_chainstate == chainman.ActiveChainstate()` checks that
will happen (as a result of assumeutxo) in functions that otherwise
don't have an easily-accessible reference to the chainstate's
ChainManager.

Moved implementations of `ConsumeTxMemPoolEntry`, `ContainsSpentInput`, `ConsumeNetAddr`, and the methods(open, read, write, seek, close) of FuzzedFileProvider from test/fuzz/util.h to test/fuzz/util.cpp.
Since we now have multiple chainstate objects, only one of them is active at any given
time. An active chainstate has a mempool, but there's no point to others having one.
This change will simplify proposed assumeutxo semantics. See the discussion here:

This is a temporary change to convert I2P addresses that have propagated
with port 8333 to ones with port 0.
It would cause a problem some day if indeed some bitcoin software is
listening on port 8333 only and rejects connections to port 0 and we are
still using SAM 3.1 which only supports port 0. In this case we would
replace 8333 with 0 and try to connect to such nodes.
This commit should be included in 22.0 and be reverted before 23.0 is
released.

00b875ba94 addrman: remove invalid addresses when unserializing (Vasil Dimov)
bdb62096f0 fuzz: reduce possible networks check (Vasil Dimov)
a164cd3ba6 net: simplify CNetAddr::IsRoutable() (Vasil Dimov)
Pull request description:
* Simplify some code, now that we know `CNetAddr::IsRFC4193()` and `CNetAddr::IsTor()` cannot be `true` at the same time.
* Drop Tor v2 addresses when loading addrman from `peers.dat` - they would have been loaded as dummy-all-zeros IPv6 addresses and linger in addrman, wasting space.
ACKs for top commit:
sipa:
ACK 00b875ba94. Reviewed the code, and tested with -DDEBUG_ADDRMAN (unit tests + mainnet run with peers.dat that contained v2 onions).
laanwj:
Code review and lightly tested ACK 00b875ba94
jonatack:
ACK 00b875ba94 reviewed, debug-built with -DEBUG_ADDRMAN rebased to current master, restarted node on mainnet/signet/testnet and verified that on each chain -addrinfo shows no change in address counts (as expected). Added some sanity check asserts, rebuilt/re-ran test. Checked that the new test fails on master with "test/addrman_tests.cpp(824): error: in "addrman_tests/remove_invalid": check addrman.size() == 2 has failed [4 != 2]"
