0e0d01913a mempool: disable full-RBF, require BIP125 opt-in signaling (Byron Hambly)
Pull request description:
Bitcoin Core defaults to accepting any fee-bumping replacement regardless of signaling (full-RBF). Revert this for Elements: only replace mempool transactions that explicitly opt in via BIP125 nSequence signaling (or TRUC), and report fullrbf=false in getmempoolinfo.
Update feature_rbf.py accordingly, and add a regression test for CVE-2021-31876 confirming that inherited signaling from an unconfirmed parent does not make a non-signaling child replaceable.

e151cada58 test: update and re-enable trim headers functional test (Byron Hambly)
3824d7dd36 add guard to TryLowWorkHeadersSync to prevent assert_untrimmed (Tom Trevethan)
Pull request description:
When -trim_headers is enabled, TryLowWorkHeadersSync can receive a chain_start_header pointing to a trimmed block index entry. The `HeadersSyncState` constructor immediately calls `GetBlockHeader()` on it via the m_last_header_received initialiser, which hits `assert_untrimmed()` and aborts the node.
Conditional untrim_to guard added inside `TryLowWorkHeadersSync`, before `HeadersSyncState`.
For nodes running -trim_headers, in practice the crash path is not reachable on Elements because `already_validated_work` is always true on a federated chain (nChainWork == nMinimumChainWork == 0), so `TryLowWorkHeadersSync` is not entered. But this ensures consistency with guarded serving paths.
`TryLowWorkHeadersSync` and `HeadersSyncState` were introduced in Bitcoin v24 (bitcoin/bitcoin#25717) and so this is not applicable to Elements v23.

The trim_headers test was previously moved to extended tests, and only
worked with legacy wallets. Update it to work with descriptor wallets,
and move it back to base scripts in functional tests.
Bitcoin Core defaults to accepting any fee-bumping replacement
regardless of signaling (full-RBF). Revert this for Elements: only
replace mempool transactions that explicitly opt in via BIP125
nSequence signaling (or TRUC), and report fullrbf=false in
getmempoolinfo.
Update feature_rbf.py accordingly, and add a regression test for
CVE-2021-31876 confirming that inherited signaling from an
unconfirmed parent does not make a non-signaling child replaceable.

test: avoid disk space warning for non-regtest
feature_config_args.py incorrectly assumed that its testnet4 node
would not log a disk space warning.
0683b8ebf3 increased m_assumed_blockchain_size
on testnet4 from 1 to 11 GiB which triggers this bug on more
systems, e.g. a RAM disk.
Prevent the warning by setting -prune for these nodes.
Fix the same issue in feature_signet.py
