rust-cpython: using MissingAncestors from Python code

As precedently done with LazyAncestors on cpython.rs, we test for the
presence of the 'rustext' module.

incrementalmissingrevs() has two callers within the Mercurial core:
`setdiscovery.partialdiscovery` and the `only()` revset.

This move shows a significant discovery performance improvement
in cases where the baseline is slow: using perfdiscovery on the PyPy
repos, prepared with `contrib/discovery-helper <repo> 50 100`, we
get averaged medians of 403ms with the Rust version vs 742ms without
(about 45% better).

But there are still indications that performance can be worse in cases
the baseline is fast, possibly due to the conversion from Python to
Rust and back becoming the bottleneck. We could measure this on
mozilla-central in cases were the delta is just a few changesets.
This requires confirmation, but if that's the reason, then an
upcoming `partialdiscovery` fully in Rust should solve the problem.

pushing a new bookmark on a new head does not require -f if -B is specified

pushing an existing but divergent bookmark with -B still requires -f

  $ echo 1 > f2

Check summary output for incoming/outgoing bookmarks

pushing an unchanged bookmark should result in no changes

Pushing a really long bookmark should work fine (issue5165)
===============================================

#if b2-binary
  >>> with open('longname', 'w') as f:
  ...     f.write('wat' * 100) and None
  $ hg book `cat longname`
  $ hg push -B `cat longname` ../unchanged-b

  $ hg -R ../unchanged-b book --delete `cat longname`
