daf5553126 Avoid calling CAddrMan::Connected() on block-relay-only peer addresses (Suhas Daftuar)
Pull request description:
This PR does two things:
* Block-relay-only interaction with addrman.
* Calling `CAddrMan::Connected()` on an address that was a block-relay-only peer causes the time we report in `addr` messages containing that peer to be updated; particularly now that we use anchor connections with a our block-relay-only peers, this risks leaking information about those peers. So, stop this.
* Avoiding calling `CAddrMan::Good()` on block-relay-only peer addresses causes the addrman logic around maintaining the new and tried table to be less good, and in particular makes it so that block-relay-only peer addresses are more likely to be evicted from the addrman (for no good reason I can think of). So, mark those addresses as good when we connect.
* Fix test-before-evict bug. There's a bug where if we get a collision in the tried table with an existing address that is one of our current peers, and the connection is long-lived enough, then `SelectTriedCollisions()` might return that existing peer address to us as a test-before-evict connection candidate. However, our logic for new outbound connections would later prevent us from actually making a connection; the result would be that when we get a collision with a long-lived current peer, that peer's address is likely to get evicted from the tried table. Fix this by checking to see if a test-before-evict candidate is a peer we're currently connected to, and if so, mark it as `Good()`.

3d0556d410 Increase feature_taproot inactive test coverage (Pieter Wuille)
525cbd425e Only relay Taproot spends if next block has it active (Pieter Wuille)
Pull request description:
There should be no change to mempool transaction behavior for witness v1 transactions as long as no activation is defined. Until that point, we should treat the consensus rules as under debate, and for soft-fork safety, that means spends should be treated as non-standard.
It's possible to go further: don't relay them unless the consensus rules are actually active for the next block. This extends non-relay to the period where a deployment is defined, started, locked in, or failed. I see no downsides to this, and the code change is very simple.

A string literal `"abc"` contains a terminating `\0`, so that is 4
bytes. There is no need to write `"abc\0"` unless two terminating
`\0`s are necessary.
`std::string` objects do not internally contain a terminating `\0`, so
`std::string("abc")` creates a string with size 3 and is the same as
`std::string("abc", 3)`.
In `"\01"` the `01` part is interpreted as one number (1) and that is
the same as `"\1"` which is a string like `{1, 0}` whereas `"\0z"` is a
string like `{0, 'z', 0}`. To create a string like `{0, '1', 0}` one
must use `"\0" "1"`.
Adjust the tests accordingly.
Since m_check_ratio is only set once and since the CTxMemPool object is
no longer a global variable, m_check_ratio can be passed into the
constructor of CTxMemPool. Since it is only read from after
initialization, m_check_ratio can also be made a const and hence no
longer needs to be guarded by the cs mutex.

Pull request description:
This is an implementation of the Schnorr/taproot consensus rules proposed by BIPs [340](https://github.com/bitcoin/bips/blob/master/bip-0340.mediawiki), [341](https://github.com/bitcoin/bips/blob/master/bip-0340.mediawiki), and [342](https://github.com/bitcoin/bips/blob/master/bip-0340.mediawiki).
See the list of commits [below](https://github.com/bitcoin/bitcoin/pull/19953#issuecomment-691815830). No signing or wallet support of any kind is included, as testing is done entirely through the Python test framework.
This is a successor to https://github.com/bitcoin/bitcoin/pull/17977 (see discussion following [this comment](https://github.com/bitcoin/bitcoin/pull/17977#issuecomment-682285983)), and will have further changes squashed/rebased. The history of this PR can be found in #19997.

Pull request description:
This replaces the transaction request logic with an encapsulated class that maintains all the state surrounding it. By keeping it stand alone, it can be easily tested (using included unit tests and fuzz tests).
The major changes are:
* Announcements from outbound (and whitelisted) peers are now always preferred over those from inbound peers. This used to be the case for the first request (by delaying the first request from inbound peers), and a bias afters. The 2s delay for requests from inbound peers still exists, but after that, if viable outbound peers remain for any given transaction, they will always be tried first.
* No more hard cap of 100 in flight transactions per peer, as there is less need for it (memory usage is linear in the number of announcements, but independent from the number in flight, and CPU usage isn't affected by it). Furthermore, if only one peer announces a transaction, and it has over 100 in flight already, we still want to request it from them. The cap is replaced with a rule that announcements from such overloaded peers get an additional 2s delay (possibly combined with the existing 2s delays for inbound connections, and for txid peers when wtxid peers are available).
* The limit of 100000 tracked announcements is reduced to 5000; this was excessive. This can be bypassed using the PF_RELAY permission (to accommodate locally dumping a batch of many transactions).
This replaces #19184, rebased on #18044 and with many small changes.

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 unit test that does generic script verification tests,
with positive/negative witnesses/scriptsigs, under various flags.
The test data is large (several MB) so it's stored in the qa-assets
repo.
This enables the schnorrsig module in libsecp256k1, adds the relevant types
and functions to src/pubkey, as well as in higher-level `SignatureChecker`
classes. The (verification side of the) BIP340 test vectors is also added.
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.

932564b9cf scripted-diff: update max-fee-exceeded error message to include RPC (gzhao408)
8f1290c601 [rpc/node] check for high fee before ATMP in clients (gzhao408)
Pull request description:
Picked up from #15810. Add separate fee-checking logic for clients that need to enforce max fee rates, then remove the `absurdFee` logic from ATMP.
ATMP's `nAbsurdFee` argument is used to enforce user-specific behavior (it is not policy since it isn't applied consistently: it is only ever used in RPC and wallet, and set to 0 everywhere else internally). It should be removed from `AcceptToMemoryPool` because (1) validation results/mempool behavior should not be user-specific and (2) enforcing a max fee rate should be the responsibility of the client instead of the mempool.
Note: this PR does not intend to _remove_ protection from high fees, just re-delegate the responsibility to clients.
