Pull request description:
Introduce a class to manage the lifetime of a socket - when the object
that contains the socket goes out of scope, the underlying socket will
be closed.
In addition, the new `Sock` class has a `Send()`, `Recv()` and `Wait()`
methods that can be overridden by unit tests to mock the socket
operations.
The `Wait()` method also hides the
`#ifdef USE_POLL poll() #else select() #endif` technique from higher
level code.

This fixes issue #19388. The changes are as follows:
- Add a new flag to configure, --enable-fuzz-binary, which allows building test/fuzz/fuzz regardless of whether we are building to do actual fuzzing
- Set -DPROVIDE_MAIN_FUNCTION whenever --enable-fuzz is no
- Add the following libraries to FUZZ_SUITE_LD_COMMON:
- LIBBITCOIN_WALLET
- SQLLITE_LIBS
- BDB_LIBS
- if necessary, some or all of:
- NATPMP_LIBS
- MINIUPNPC_LIBS
- LIBBITCOIN_ZMQ / ZMQ_LIBS

32def8d1c2 Catch ios_base::failure specifically (Peter Bushnell)
Pull request description:
In https://github.com/bitcoin/bitcoin/pull/2950 a hash of the pubkey and private was added to speed up key import, this was made backwards compatible by reading the hash in a try block with an ellipses catch all in case the hash was not present.
CDataStream::read() specifically throws std::ios_base::failure, backwards compatibility expects only that error to be thrown, if something else gets thrown we should not be catching it. The change in this commit is to catch that exception only. If any other exception is thrown other than std::ios_base::failure it will be caught by the wider try block and an error written to the log and/or console.
CDataStream::read() throwing std::ios_base::failure.

Pull request description:
This PR adds a new class `SQLiteDatabase` which is a subclass of `WalletDatabase`. This provides access to a SQLite database that is used to store the wallet records. To keep compatibility with BDB and to complexity of the change down, we don't make use of many SQLite's features. We use it strictly as a key-value store. We create a table `main` which has two columns, `key` and `value` both with the type `blob`.
For new descriptor wallets, we will create a `SQLiteDatabase` instead of a `BerkeleyDatabase`. There is no requirement that all SQLite wallets are descriptor wallets, nor is there a requirement that all descriptor wallets be SQLite wallets. This allows for existing descriptor wallets to work as well as keeping open the option to migrate existing wallets to SQLite.
We keep the name `wallet.dat` for SQLite wallets. We are able to determine which database type to use by searching for specific magic bytes in the `wallet.dat` file. SQLite begins it's files with a null terminated string `SQLite format 3`. BDB has `0x00053162` at byte 12 (note that the byte order of this integer depends on the system endianness). So when we see that there is a `wallet.dat` file that we want to open, we check for the magic bytes to determine which database system to use.
I decided to keep the `wallet.dat` naming to keep things like backup script to continue to function as they won't need to be modified to look for a different file name. It also simplifies a couple of things in the implementation and the tests as `wallet.dat` is something that is specifically being looked for. If we don't want this behavior, then I do have another branch which creates `wallet.sqlite` files instead, but I find that this direction is easier.

Code review ACK c4a29d0a90. I am honestly confused about reasons for locking into `wallet.dat` again when it's so easy now to use a clean format. I assume I'm just very dense, or there's some unstated reason, because the only thing that's been brought up are unrealistic compatibility scenarios (all require actively creating a wallet with non-default descriptor+sqlite option, then trying to using the descriptor+sqlite wallets with old software or scripts and ignoring the results) that we didn't pay attention to with previous PRs like #11687, which did not require any active interfaction.

This adds a --dumptests flag to the feature_taproot.py test, to dump all its
generated test cases to files, in a format compatible with the
script_assets_test unit test. A fuzzer for said format is added as well, whose
primary purpose is coverage-based minimization of those dumps.
This adds a fuzz test that reimplements a naive reimplementation of
TxRequestTracker (with up to 16 fixed peers and 16 fixed txhashes),
and compares the real implementation against it.
Note that with this change we are no-longer including PTHREAD_* flags
when building libbitcoinconsensus.
Also note that we are including PTHREAD_LIBS in AM_PTHREAD_FLAGS

With this commit, make clean now removes coverage files from the

garbled coverage signals for files in the fuzz directory as
they were never deleted with make clean.
78c312c983 Replace current benchmarking framework with nanobench (Martin Ankerl)
Pull request description:
Replace current benchmarking framework with nanobench
This replaces the current benchmarking framework with nanobench [1], an
MIT licensed single-header benchmarking library, of which I am the
autor. This has in my opinion several advantages, especially on Linux:
* fast: Running all benchmarks takes ~6 seconds instead of 4m13s on
an Intel i7-8700 CPU @ 3.20GHz.
* accurate: I ran e.g. the benchmark for SipHash_32b 10 times and
calculate standard deviation / mean = coefficient of variation:
* 0.57% CV for old benchmarking framework
* 0.20% CV for nanobench
So the benchmark results with nanobench seem to vary less than with
the old framework.
* It automatically determines runtime based on clock precision, no need
to specify number of evaluations.
* measure instructions, cycles, branches, instructions per cycle,
branch misses (only Linux, when performance counters are available)
* output in markdown table format.
* Warn about unstable environment (frequency scaling, turbo, ...)
* For better profiling, it is possible to set the environment variable
NANOBENCH_ENDLESS to force endless running of a particular benchmark
without the need to recompile. This makes it to e.g. run "perf top"
and look at hotspots.

Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal
---
In the assumeutxo implementation draft (#15056), once a UTXO snapshot is loaded, a new chainstate object is created after initialization. This means that we have to reclaim some of the cache that we've allocated to the original chainstate (per `dbcache=`) to repurpose for the snapshot chainstate.
Furthermore, it makes sense to have different cache allocations depending on which chainstate is more active. While the snapshot chainstate is working to get to the network tip (and the background validation chainstate is idle), it makes sense that the snapshot chainstate should have the majority of cache allocation. And contrariwise once the snapshot has reached network tip, most of the cache should be given to the background validation chainstate.
This set of changes (detailed in the commit messages) allows us to dynamically resize the various coins caches. None of the functionality introduced here is used at the moment, but will be in the next AU PR (which introduces `ActivateSnapshot`).
`ChainstateManager::MaybeRebalanceCaches()` defines the (somewhat normative) cache allocations between the snapshot and background validation chainstates. I'd be interested in feedback if anyone has thoughts on the proportions I've set there.

Pull request description:
Add fuzzing harnesses for `CAutoFile`, `CBufferedFile`, `LoadExternalBlockFile` and other `FILE*` consumers:
* Add `FuzzedFileProvider` which provides a `FILE*` interface to `FuzzedDataProvider` using `fopencookie`
* Add `FuzzedAutoFileProvider` which provides a `CAutoFile` interface to `FuzzedDataProvider`
* Add serialization/deserialization fuzzing helpers `WriteToStream(…)`/`ReadFromStream(…)`
* Add fuzzing harness for `CAutoFile` (`streams.h`)
* Add fuzzing harness for `CBufferedFile` (`streams.h`)
* Add fuzzing harness for `LoadExternalBlockFile(...)` (`validation.h`)
* Add fuzzing harness for `CBlockPolicyEstimator::Read` and `CBlockPolicyEstimator::Write` (`policy/fees.h`)

fa525e4d1c net: Avoid wasting inv traffic during IBD (MarcoFalke)
fa06d7e934 refactor: block import implies IsInitialBlockDownload (MarcoFalke)
faba65e696 Add ChainstateManager::ActiveChainstate (MarcoFalke)
fabf3d64ff test: Add FeeFilterRounder test (MarcoFalke)
Pull request description:
Tx-inv messages are ignored during IBD, so it would be nice if we told peers to not send them in the first place. Do that by sending two `feefilter` messages: One when the connection is made (and the node is in IBD), and another one when the node leaves IBD.
