branchmap-v3: introduce a "stop_rev" argument to `headsrevs`

The `headsrevs` method of the revlog already have a `revs` argument to compute
the headrevs of a limited set of heads. However, it disable the use of the
native compiled code to compute the heads, which slows down the branchmap v3
code a lot.

The branchmap v3 usage is actually quite constrained as we will always only
ignores a part at the top of the graph. So we could be significantly faster.

We start by making small change to the python side to improve the situation and
introduce the new API. More collaboration with the native code are coming later.

This massively speedup operation and close most of the remaining gaps between
branchmap-v3 and branchmap-v2. especially on repository with many revs like
mozilla-try. A small overhead remains mostly because the `headrevs` logic
currently has some inefficiently. We will look into them from there.

Verify that Mercurial is installable with pip. Note that this MUST be
the last test in this file, because we do some nasty things to the
shell environment in order to make the virtualenv work reliably.

On Python 3, we use the venv module, which is part of the standard library.
But some Linux distros strip out this module's functionality involving pip,
so we have to look for the ensurepip module, which these distros strip out
completely.
On Python 2, we use the 3rd party virtualenv module, if available.

  $ cd $TESTTMP
  $ unset PYTHONPATH

#if py3 ensurepip network-io no-pyoxidizer
  $ "$PYTHON" -m venv installenv >> pip.log

Hack: Debian does something a bit different in ensurepip.bootstrap. This makes
it so that pip thinks the 'wheel' wheel is installed so it can build wheels;
when it goes to try, however, it shells out to run `python3 -u <setup.py>`,
that *doesn't* get the 'wheel' wheel, and it fails with an invalid command
'bdist_wheel'. To fix this, we just delete the wheel from where Debian put it in
our virtual env. Then pip doesn't think it's installed and doesn't try to build.
  $ rm installenv/share/python-wheels/wheel-*.whl >/dev/null 2>&1 || true

Note: we use this weird path to run pip and hg to avoid platform differences,
since it's bin on most platforms but Scripts on Windows.
