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. I assume this was last generated on Linux, and noticed this trying to add another package and regenerating on Windows. Differential Revision: https://phab.mercurial-scm.org/D9404

pyoxidizer: point to the py3 requirements instead of py2 on Windows Differential Revision: https://phab.mercurial-scm.org/D9406

git: update test for hg and git output changes Clearly nobody is running this in their CI. :( Differential Revision: https://phab.mercurial-scm.org/D9403

gitlog: add tiprev() function Lots of stuff was broken because this was missing. Differential Revision: https://phab.mercurial-scm.org/D9402

requirements: move loading to hg-core and add parsing No functional change, checking comes later. Differential Revision: https://phab.mercurial-scm.org/D9398

rhg: add a `debugrequirements` subcommand For now it only prints the contents of `.hg/requires` as-is, without parsing. Differential Revision: https://phab.mercurial-scm.org/D9397
