git: show the version of `pygit2` with verbose version output

This seems like useful info to have when debugging.  I followed the precedent of
hg-git, which prints something like:

      hggit        external  0.9.0a1 (dulwich 0.19.15)

We don't have a version number assigned (because it's internal), so it's just
the parenthetical.

# Dummy extension to define a namespace containing revision names

from __future__ import absolute_import

from mercurial import namespaces


def reposetup(ui, repo):
    names = {b'r%d' % rev: repo[rev].node() for rev in repo}
    namemap = lambda r, name: names.get(name)
    nodemap = lambda r, node: [b'r%d' % repo[node].rev()]

    ns = namespaces.namespace(
        b'revnames',
        templatename=b'revname',
        logname=b'revname',
        listnames=lambda r: names.keys(),
        namemap=namemap,

    )
    repo.names.addnamespace(ns)
