Should revisit; I am not sure whether we have a long-term stable
URL for prebuilt past Elements releases, but we should be able
to just point test/get-previous-releases.py at that, and change
the set of versions (since we do not have 0.15, 0.19, etc), and
we're good to go.
Everyone is _not_ connected in this test, so on slow machines
where this check triggers (e.g. the CI boxes) the test incorrectly
fails. This was also a source of (very infrequent) spurious failures
during the rebase.
It may be that we just need to recompute some numbers because our
block limits are different. But this test takes 20 minutes to
fail and it would take some time to understand what the expected
behavior is.
Several conflicts in the C++ code related to the new `flags` parameter
to `CheckSignature` and the corresponding function being renamed upstream
to `CheckSignatureECDSA`.
Several conflicts in the test harness as Steven sorta pulled the new
upstream ECKey module into the Python code, and the actual upstream
code was slightly different. Also needed to update the feature_taproot
code to always use the non-RANGEPROOF sighash since dynafed is not
enabled in the Taproot test.
Also had to pull the `set_wif` method out of `ECKey` and inline it because
otherwise it triggers a "circular inclusion" error between script.py (which
would pull in `base58_to_bytes` from address.py) and address.py (which now
pulls in some taproot EC related stuff from script.py).
Noticed that #960 does not test the "sighash rangeproof flag set but no
witnesses" case.

Somehow the CECKey impl is really broken if you want to set
a raw private key. Core master already has a new impl so I just
took that one and replaces the usages. This will probably be equivalent
with what would be rebased in at a later stage.
fa40168ab3 Remove unused bits from service flags enum (MarcoFalke)
Pull request description:
Remove service bits that haven't been observed on the active network for years and won't ever be observed on the network with this meaning. Keeping this dead assignment in our source code forever doesn't add any value.
I somehow forgot to do this in commit fa0d0ff6e1.

1583498fb6 Send and require SENDADDRV2 before VERACK (Pieter Wuille)
c5a8919660 Don't send 'sendaddrv2' to pre-70016 software (Pieter Wuille)
Pull request description:
BIP155 defines addrv2 and sendaddrv2 for all protocol versions, but some implementations reject messages they don't know. As a courtesy, don't send it to nodes with a version before 70016, as no software is known to support BIP155 that doesn't announce at least that protocol version number.
Also move the sending of sendaddrv2 earlier (before sending verack), as proposed in https://github.com/bitcoin/bips/pull/1043. This has the side effect that local address broadcast of torv3 will work (as it'll only trigger after we know whether or not the peer supports addrv2).

fa275e1539 test: Fix intermittent feature_taproot issue (MarcoFalke)
Pull request description:
The nodes might disconnect (e.g. due to "Timeout downloading block" https://cirrus-ci.com/task/5313800947630080?command=ci#L1763) and the test fails to continue.
Fix that by reconnecting the nodes.

86ff2cf202 Remove the remaining fee estimation globals (Antoine Poinsot)
03bfeee957 interface: remove unused estimateSmartFee method from node (Antoine Poinsot)
Pull request description:
If the `blocksonly` mode is turned on after running with transaction
relay enabled for a while, the fee estimation will serve outdated data
to both the internal wallet and to external applications that might be
feerate-sensitive and make use of `estimatesmartfee` (for example a
Lightning Network node).
This has already caused issues (for example https://github.com/bitcoin/bitcoin/issues/16840 (C-lightning), or https://github.com/lightningnetwork/lnd/issues/2562 (LND)) and it seems prudent to fail rather than to give inaccurate values.
This fixes#16840, and closes#16890 which tried to fix the symptoms (RPC) but not the cause as mentioned by sdaftuar :
> If this is a substantial problem, then I would think we should take action to protect our own wallet users as well (rather than hide the results of what our fee estimation would do!).
