Pull request description:
This PR attempts to solve the problem explained in #16599.
A particular attack which encouraged us to work on this issue is explained here [[Erebus Attack against Bitcoin Peer-to-Peer Network](https://erebus-attack.comp.nus.edu.sg/)] (by @muoitranduc)
Instead of relying on /16 prefix to diversify the connections every node creates, we would instead rely on the (ip -> ASN) mapping, if this mapping is provided.
A .map file can be created by every user independently based on a router dump, or provided along with the Bitcoin release. Currently we use the python scripts written by @sipa to create a .map file, which is no larger than 2MB (awesome!).
Here I suggest adding a field to peers.dat which would represent a hash of asmap file used while serializing addrman (or 0 for /16 prefix legacy approach).
In this case, every time the file is updated (or grouping method changed), all buckets will be re-computed.
I believe that alternative selective re-bucketing for only updated ranges would require substantial changes.
TODO:
- ~~more unit tests~~
- ~~find a way to test the code without including >1 MB mapping file in the repo.~~
- find a way to check that mapping file is not corrupted (checksum?)
- comments and separate tests for asmap.cpp
- make python code for .map generation public
- figure out asmap distribution (?)
~Interesting corner case: I’m using std::hash to compute a fingerprint of asmap, and std::hash returns size_t. I guess if a user updates the OS to 64-bit, then the hash of asap will change? Does it even matter?~

b35567fe0ba3e6f8d8f9525088eb8ee62065ad01 test: only declare a main() when fuzzing with AFL (fanquake)
Pull request description:
This fixes fuzzing using [libFuzzer](https://llvm.org/docs/LibFuzzer.html) on macOS, which caused a few issues during the recent review club. macOS users could only fuzz using afl, or inside a VM.
It seems that the `__attribute__((weak))` marking is not quite enough to properly mark `main()` as weak on macOS. See Apples docs on [Frameworks and Weak Linking](https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html#//apple_ref/doc/uid/20002378-107262-CJBJAEID).
Have tested fuzzing using libFuzzer and AFL with this patch.

f1ef7f0aa46338f4cd8de79696027a1bf868f359 Don't calculate tx fees for PSBTs with invalid money values (Andrew Chow)
Pull request description:
Fixes #17149
Two classes of issues were found by the psbt fuzzer: values out of range and causing overflows, and prevout indexes being out of range. This PR fixes both.
When accessing a specific output using the index given in the tx, check that it is actually a possible output before trying to access the output.
When summing and checking amounts for `decodepsbt` and `analyzepsbt`, make sure that the values are actually valid money values.. Otherwise, stop summing and don't show the fee. For `analyzepsbt`, return that the next role is the Creator since the Creator needs to remake the transaction to be valid.

Quoting src/test/README.md, 'Adding test cases':
"The file naming convention is `<source_filename>_tests.cpp`

called `<source_filename>_tests`."
Currently the unit test source file txvalidationcache_tests.cpp contains a unit
test suite with the name tx_validationcache_tests, which is fixed by this commit.

unit test source files the test suite names are correct:

Needed for future ScriptPubKeyMans which may need to create
SigningProviders dynamically and thus a normal pointer is not enough
This commit does not change behavior.
Add wallet logic for dealing with multiple ScriptPubKeyMan instances. This
doesn't change current behavior because there is still only a single
LegacyScriptPubKeyMan. But in the future the new logic will be used to support
descriptor wallets.

75163f4729c10c40d2843da28a8c79ab89193f6a bug-fix macos: give free bytes to F_PREALLOCATE (Karl-Johan Alm)
Pull request description:
The macos manpage for `fcntl` (for `F_PEOFPOSMODE`) states:
> Allocate from the physical end of file. In this case, fst_length indicates the number of newly allocated bytes desired.
This would result in the rev files being essentially pre-allocating 2x their necessary size (this is the case for block files as well, but these are flushed down to their right sizes every time) as they would pre-allocate `pos + length` **free** bytes, rather than allocating `length` bytes after `pos`, as expected.

9dd58ca611f6f2b59c25d727a4e955333525d345 init: Stop indexes on shutdown after ChainStateFlushed callback. (Jim Posen)
Pull request description:
Replaces https://github.com/bitcoin/bitcoin/pull/17852.
Currently, the latest index state may not be committed to disk on shutdown. The state is committed on `ChainStateFlushed` callbacks and the current init order unregisters the indexes as validation interfaces before the final `ChainStateFlushed` callback is called on them.
Issue identified by paulyc.
For review: an alternative or supplemental solution would be to call `Commit` at the end of `BaseIndex::Stop`. I don't see any harm in doing so and it makes the less prone to user error. However, the destructor would have to be modified to not call `Stop` because `Commit` calls a virtual method, so I figured it wasn't worth it. But I'm curious how others feel.
