py3: port f to Python 3

This involved a lot of b'' literals, conversion from %s to %d, and
using a hashing mechanism that returns bytes instead of str.

Make sure hg is really paranoid in serve --stdio mode. It used to be
possible to get a debugger REPL by specifying a repo named --debugger.
  $ hg -R --debugger serve --stdio

  abort: potentially unsafe serve --stdio invocation: ['-R', '--config=ui.debugger=yes', 'serve', '--stdio']

Abbreviations of 'serve' also don't work, to avoid shenanigans.

  abort: potentially unsafe serve --stdio invocation: ['-R', 'narf', 'serv', '--stdio']
