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.

helptext: byteify extensions examples Make it easier on the copy/paste crowd. I haven't looked at the other help text to see if there are other instances; I was just looking to confirm `buglink` is meant to be bytes and this popped up along with the code.

ui: ensure `getpass()` returns bytes Previously, this could return either bytes or str. I'm not sure which direction we should go in, but since the input is bytes, I guess bytes makes sense as output. `debuguigetpass` crashed because it assumed bytes would be returned, `sslcontext.load_cert_chain()` is happy with bytes or str if the type info in PyCharm is correct, and `smtplib.SMTP.login()` wants str. I couldn't figure out how to test this, because the test stalls for input with `echo test | hg debuguigetpass --config ui.interactive=1`, likely because it drains stdin before prompting. The custom input reading with `ui.nontty=1` does not. I'm also a bit concerned with all of this encoding/decoding. The existing code in the mail module uses `encoding.strfromlocal()`, but the username and password are ascii encoded/decoded in `mercurial.url.passwordmgr.find_user_password()` with `pycompat.{str,bytes}url()`. I'm not sure if this inconsistency could cause subtle compatability issues. Differential Revision: https://phab.mercurial-scm.org/D9375

packaging: regenerate the Windows requirements manifest on Windows SecretStorage is a Linux package, and the other stuff removed is a dependency of it.

pyoxidizer: make sure defaultrc directory exists before trying to write to it When doing some work involving one-file binaries, this line is failing for me.
