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.
This one was pretty brutal, but ultimately nothing too surprising.
Just had to keep track of which wallets owned which blinding keys,
and in wallet_importprunedfunds.py I had to manually create a
Liquid address.
