4b7091a842 Replace median fee rate with feerate percentiles (Marcin Jachymiak)
Pull request description:
Currently, the `medianfeerate` statistic is calculated from the feerate of the middle transaction of a list of transactions sorted by feerate.
This PR instead uses the value of the 50th percentile weight unit in the block, and also calculates the feerate at the 10th, 25th, 75th, and 90th percentiles. This more accurately corresponds with what is generally meant by median feerate.

e306be7429 Use 72 byte dummy signatures when watching only inputs may be used (Andrew Chow)
48b1473c89 Use 71 byte signature for DUMMY_SIGNATURE_CREATOR (Andrew Chow)
18dfea0dd0 Always create 70 byte signatures with low R values (Andrew Chow)
Pull request description:
When creating signatures for transactions, always make one which has a 32 byte or smaller R and 32 byte or smaller S value. This results in signatures that are always less than 71 bytes (32 byte R + 32 byte S + 6 bytes DER + 1 byte sighash) with low R values. In most cases, the signature will be 71 bytes.
Because R is not mutable in the same way that S is, a low R value can only be found by trying different nonces. RFC 6979 for deterministic nonce generation has the option to specify additional entropy, so we simply use that and add a uin32_t counter which we increment in order to try different nonces. Nonces are sill deterministically generated as the nonce used will the be the first one where the counter results in a nonce that results in a low R value. Because different nonces need to be tried, time to produce a signature does increase. On average, it takes twice as long to make a signature as two signatures need to be created, on average, to find one with a low R.
Having a fixed size signature makes size calculations easier and also saves half a byte of transaction size, on average.
DUMMY_SIGNATURE_CREATOR has been modified to produce 71 byte dummy signatures instead of 72 byte signatures.

Removes medianfeerate result from getblockstats.
Adds feerate_percentiles which give the feerate of the 10th, 25th, 50th,
75th, and 90th percentile weight unit in the block.
When extra entropy is not specified by the caller, CKey::Sign will
now always create a signature that has a low R value and is at most
70 bytes. The resulting signature on the stack will be 71 bytes when
the sighash byte is included.
Using low R signatures means that the resulting DER encoded signature
will never need to have additional padding to account for high R
values.

It changes the RPC to use descriptors for everything; I hope the interface is simple enough to encompass all use cases. It includes support for P2PK, P2PKH, P2WPKH, P2SH, P2WSH, multisig, xpubs, xprvs, and chains of keys - combined in every possible way.

9994d01d8b Add Unit Test for SingleThreadedSchedulerClient (Jesse Cohen)
Pull request description:
As discussed in #13023 I've split this test out into a separate pr
This test (and documentation update) makes explicit the guarantee (previously undefined, but implied by the 'SingleThreaded' in `SingleThreadedSchedulerClient()`) - that callbacks pushed to the `SingleThreadedSchedulerClient()` obey the single threaded model for memory and execution - specifically, the callbacks are executed fully and in order, and even in cases where a subsequent callback is executed by a different thread, sequential consistency of memory for all threads executing these callbacks is maintained.
Maintaining memory consistency should make the api more developer friendly - especially for users of the validationinterface. To the extent that there are performance implications from this decision, these are not currently present in practice because all use of this scheduler happens on a single thread currently, furthermore the lock should guarantee consistency across callback executions even when callbacks are executed by multiple threads (as the test does).

e3245f2e7b Removes Boost predicate.hpp dependency (251)
Pull request description:
This pull request removes the `boost/algorithm/string/predicate.hpp` dependency from the project.
To replace the the `predicate.hpp` dependency from the project the function calls to `boost::algorithm::starts_with` and `boost::algorithm::ends_with` have been replaced with respectively C++11's `std::basic_string::front` and `std::basic_string::back` function calls.
Refactors that were not required, but have been done anyways:
- The Boost function `all` was implicitly made available via the `predicate.hpp` header. Instead of including the appropriate header, function calls to `all` have been replaced with function calls to `std::all_of`.
- The `boost::algorithm::is_digit` predicate has been replaced with a custom `IsDigit` function that is locale independent and ASCII deterministic.

As part of a larger effort to decouple net_processing and validation a bit, these are a bunch of simple scope cleanups. I've moved things out of the header file that are only referenced in net_processing and added static (or anonymous namespace) modifiers to everything possible in net_processing.
There are a handful of functions which could be static except that they are exposed for the sake of unit testing - these are explicitly commented. There has been some discussion of a compile time annotation, but no conclusion has been reached on that yet.
This is somewhat related to other prs #12934#13413#13407 and will be followed by prs that reduce reliance on cs_main to synchronize data structures which are translation unit local to net_processing

0422beb9b Make SignatureData able to store signatures and scripts (Andrew Chow)
b6edb4f5e Inline Sign1 and SignN (Andrew Chow)
Pull request description:
Currently CombineSignatures is used to create the final scriptSig or an input. However ProduceSignature is capable of doing this itself. Using both CombineSignatures and ProduceSignature results in code duplication which is unnecessary.
To move the scriptSig construction to ProduceSignatures, the SignatureData class contains two maps to hold pubkeys mapped to signatures, and script ids mapped to scripts. DataFromTransaction is extended to be able to extract signatures, their public keys, and scripts from existing ScriptSigs.
The SignaureData are then passed down to SignStep which can use the aforementioned maps to get the signatures, pubkeys, and scripts that it needs, falling back to the actual SigningProvider and SignatureCreator if the data are not available in the SignatureData.
Additionally, Sign1 and SignN have been removed and their functionality inlined into SignStep since Sign1 is really just a wrapper around CreateSig.
Since ProduceSignature can produce the final scriptSig or scriptWitness by using SignatureData which has extracted data from the transaction, CombineSignatures is unnecessary as ProduceSignature is able to replicate all of CombineSignatures' functionality.
This also furthers BIP 174 support and begins moving towards a BIP 174 style backend.
The tests have also been updated to use the new combining methodology.

07c493f2d scripted-diff: Replace NET_TOR with NET_ONION (wodry)
Pull request description:
This is a follow-up to #13532, where @promag already asked if this renaming would make sense.
If network shall be named _Onion_ instead of _Tor_ (like in the option `onlynet`), renaming the network enum NET_TOR to NET_ONION maybe would make sense and be stringent.
Change was produced with the following script:
```
#!/bin/bash
for file in $(grep --exclude-dir='.git' --files-with-matches --binary-files=without-match --recursive NET_TOR bitcoin/)
do
sed --in-place --expression='s/NET_TOR/NET_ONION/g' $file
done
```
_Tor_ is used at many other places in the code, though.

* In https://github.com/bitcoin/bitcoin/pull/13142#issuecomment-386396975 it was suggested to merge `isInvalid` into the return status. This PR takes a different approach, and removes the `isInvalid` entirely. It was only ever used inside tests, as normal users of IsMine don't care about the reason for non-mine-ness, only whether it is or not. As the unit tests are extensive enough, it seems sufficient to have a black box text (with tests for both compressed and uncompressed keys).
Some addition code simplification is done as well.

In addition to having the scriptSig and scriptWitness, have SignatureData
also be able to store just the signatures (pubkeys mapped to sigs) and
scripts (script ids mapped to scripts).
Also have DataFromTransaction be able to extract signatures and scripts
from the scriptSig and scriptWitness of an input to put them in SignatureData.
Adds a new SignatureChecker which takes a SignatureData and puts pubkeys
and signatures into it when it successfully verifies a signature.
Adds a new field in SignatureData which stores whether the SignatureData
was complete. This allows us to also update the scriptSig and
scriptWitness to the final one when updating a SignatureData with another
one.

0df017889b Benchmark Merkle root computation (Pieter Wuille)
Pull request description:
This introduces a framework for specialized double-SHA256 with 64 byte inputs. 4 different implementations are provided:
* Generic C++ (reusing the normal SHA256 code)
* Specialized C++ for 64-byte inputs, but no special instructions
* 4-way using SSE4.1 intrinsics
* 8-way using AVX2 intrinsics
On my own system (AVX2 capable), I get these benchmarks for computing the Merkle root of 9001 leaves (supported lengths / special instructions / parallellism):
* 7.2 ms with varsize/naive/1way (master, non-SSE4 hardware)
* 5.8 ms with size64/naive/1way (this PR, non-SSE4 capable systems)
* 4.8 ms with varsize/SSE4/1way (master, SSE4 hardware)
* 2.9 ms with size64/SSE4/4way (this PR, SSE4 hardware)
* 1.1 ms with size64/AVX2/8way (this PR, AVX2 hardware)

97c112d4ca Declare TorReply parsing functions in torcontrol_tests (Ben Woosley)
Pull request description:
These methods are standalone string parsing methods which were included
into test via an include of torcontrol.cpp, which is bad practice.
~~Splitting them out reveals that they were the only torcontrol.cpp
methods under test, so the test file is renamed tor_reply_tests.cpp.~~
Introduced in #10408

fac1223a56 Cache witness hash in CTransaction (MarcoFalke)
faab55fbb1 Make CMutableTransaction constructor explicit (MarcoFalke)
Pull request description:
This speeds up:
* compactblocks (v2)
* ATMP
* validation and miner (via `BlockWitnessMerkleRoot`)
* sigcache (see also unrelated #13204)
* rpc and rest (nice, but irrelevant)
This presumably slows down rescan, which uses a `CTransaction` and its `GetHash`, but never uses the `GetWitnessHash`. The slow down is proportional to the number of witness transactions in the rescan window. I.e. early in the chain there should be no measurable slow down. Later in the chain, there should be a slow down, but acceptable given the speedups in the modules mentioned above.

60ebc7da4c trivial: Mark overrides as such. (Daniel Kraft)
Pull request description:
This trivial change adds the `override` keyword to some methods that override virtual base class / interface methods. This ensures that any future changes to the interface's method signatures which are not correctly mirrored in the subclasses will break at compile time with a clear error message, rather than at runtime.
