d438d609cd QA: Use GBT to get block versions correct (Luke Dashjr)
1df2cd1c8f QA: blocktools: Accept block template to create_block (Luke Dashjr)
Pull request description:
The goal here is to decouple unrelated tests from the details of block versions.
Currently, these tests are forcing specific versions of blocks for no real reason.

Pull request description:
We no longer send BIP 61 REJECT messages, so there's no need to set
a REJECT code in the CValidationState object.
Note that there is a minor bug fix in p2p behaviour here. Because the
call to `MaybePunishNode()` in `PeerLogicValidation::BlockChecked()` only
previously happened if the REJECT code was > 0 and < `REJECT_INTERNAL`,
then there are cases were `MaybePunishNode()` can get called where it
wasn't previously:
- when `AcceptBlockHeader()` fails with `CACHED_INVALID`.
- when `AcceptBlockHeader()` fails with `BLOCK_MISSING_PREV`.
Note that `BlockChecked()` cannot fail with an 'internal' reject code. The
only internal reject code was `REJECT_HIGHFEE`, which was only set in
ATMP.
This reverts a minor bug introduced in 5d08c9c579.

Addresses #17043, affects RBF and BIP68 functional tests.
The "tx-size-small" policy rule rejects transactions with a non-witness size of
smaller than 82 bytes (see src/validation.cpp:MemPoolAccept::PreChecks(...)),
which corresponds to a transaction with 1 segwit input and 1 P2WPKH output.
Through the default address change, the created test transactions have segwit
inputs now and sending to short scriptPubKeys might violate this rule. By
bumping the dummy scriptPubKey size to 22 bytes (= the size of a P2WPKH
scriptPubKey), on all occurences the problem is solved.
The dummy scriptPubKey has the format:
21 <21-byte-long string of 'a' or 1s>
former commit messages, now squashed:
test: rbf, bip68: use constant DUMMY_P2WPKH_SCRIPT for bumped scriptPubKey
test: rbf, bip68: use constant DUMMY_P2WPKH_SCRIPT for dummy scriptPubKeys (b'a' * 35)
test: rbf, bip68: comment DUMMY_P2WPKH_SCRIPT constant, put into common (new) module
Remove the BIP61 REJECT code from error messages and logs when a
transaction is rejected.
BIP61 support was removed from Bitcoin Core in
fa25f43ac5. The REJECT codes will be
removed from the codebase entirely in the following commit.
Unnamed arguments are confusing as to what they mean without looking up
the function signature.
Since segwit is active by default in regtest, and all blocks are
serialized with witness (#15664, c459c5f), remove the argument
`with_witness=True` from all calls to `CBlock::serialize` and
`BlockTransactions::serialize`.
This diff has been created with a script, but is better reviewed without
a scripted diff.

Pull request description:
This disables `OP_CODESEPARATOR` in non-segwit scripts (even in an unexecuted branch), and makes a positive `FindAndDelete` result invalid. This ensures that the `scriptCode` serialized in `SignatureHash` is always the same as the script passing to the `EvalScript`.
