revlog: store new index entries as binary For a pure-Python unbundle of the current NetBSD test repository, this results in a 10% peak RSS reduction. Using the C revlog index, it shows 25% peak RSS reduction. This is a direct result of avoiding at least 8 objects per new changeset or 200 Bytes+ on AMD64.

tests: use `testrepohg` in one more place in test-check-code.t This is already used elsewhere in the test to access the current hg repo, and avoids an error about the unknown `revlog-compression-zstd` when C extensions aren't built. The only other such error is in test-check-interfaces.py, but I don't see a way to avoid it other than to create an empty scratch repo. Differential Revision: https://phab.mercurial-scm.org/D9364

setup: copy pythonXY.dll next to the hg.exe wrapper when building This avoids the problem of having the newly built binary complaining that it can't find the DLL. There is an option in the python.org installer to add the python install to PATH (which defaulted to "on" with py2, and therefore was not an issue up to this point), but that makes switching between python versions harder. This shouldn't be an issue with the PyOxidizer binary, but that current has issues running some of the tests, and took noticeably longer to build last time I tried it.
