final merge master branch into libevm branch

[qdm12]

Why this should be merged

This will, as before, need to be ff-only merged into libevm, from a terminal, once checks are passing on the PR.

How this works

How this was tested

Need to be documented?

Need to update RELEASES.md?

This is merging master at eb18358, one commit behind where it currently is (59099cc). Please bring it up to date. A force push to this branch will be necessary, but that's OK because we're reviewing commit histories, not individual changes.

Graph looks good:

git log --oneline --graph origin/qdm12/libevm/merge-master-1 libevm master --

And merge commits show inconsequential conflict resolution, e.g.

$ git show d60e65e
...
diff --cc internal/ethapi/api.coreth.go
...
 -      chainConfig := s.b.ChainConfig()
++      chainConfig := params.GetExtra(s.b.ChainConfig())
...
