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.
The "whitelist" and "connect_nodes" is not needed in feature_taproot.py,
so remove it.
The changes to key.py are required when running the unit tests from the
test folder. Failure on current master:
[test]$ python -m unittest functional/test_framework/key.py

This adds a --dumptests flag to the feature_taproot.py test, to dump all its
generated test cases to files, in a format compatible with the
script_assets_test unit test. A fuzzer for said format is added as well, whose
primary purpose is coverage-based minimization of those dumps.
A large functional test is added that automatically generates random transactions which
exercise various aspects of the new rules, and verifies they are accepted into the mempool
(when appropriate), and correctly accepted/rejected in (Python-constructed) blocks.
Includes sighashing code and many tests by Johnson Lau.
Includes a test by Matthew Zipkin.
Includes several tests and improvements by Greg Sanders.
