typing: add type hints to `mercurial.policy`

Mostly trivial, but this seems like the logical module to use to inject the
hints from `cext`, `pure`, etc, given that this file has the fallback policy.
This is a first step.

There doesn't appear to be a predefined type for a module in py3.7, so those are
omitted for now.

import sys


def flush():
    sys.stdout.flush()
    sys.stderr.flush()


globalvars = {}
lines = sys.stdin.readlines()
while lines:
    l = lines.pop(0)
    if l.startswith('SALT'):
        print(l[:-1])
    elif l.startswith('>>> '):
        snippet = l[4:]
        while lines and lines[0].startswith('... '):
            l = lines.pop(0)
            snippet += l[4:]
        c = compile(snippet, '<heredoc>', 'single')
        try:
            flush()
            exec(c, globalvars)
            flush()
        except Exception as inst:
            flush()
            print(repr(inst))
