typing: add type hints to most mercurial/pycompat.py functions
The `rapply` methods are left out because it's not `rapply(f, xs: _T0) -> _T0`
as I first thought- it's used somewhere to walk a collection and convert between
bytes and str.
Also, the `open()` call is partially untyped because I'm not sure what its
purpose is at this point- both the name and mode can be either bytes or str as
it is currently constituted. It might make sense to assert that the file is
being opened in binary mode (like `namedtempfile()`) and cast the result to
`BinaryIO`, but that shouldn't be smuggled in with these other changes. The
return is currently typed as `Any` because something suddenly got smarter and a
few uses in util.py (like readfile()) suddenly think it returns `IO[str]`
instead of `IO[bytes]` (BinaryIO), and it flags the type mismatch there.

# Many of the individual files that are excluded here confuse pytype
# because they do a mix of Python 2 and Python 3 things
# conditionally. There's no good way to help it out with that as far as
# I can tell, so let's just hide those files from it for now. We should
# endeavor to empty this list out over time, as some of these are
# probably hiding real problems.
