    Properly check for git before getting git dir

    We cannot get the git dir if git is not installed. Check that git is
    installed before querying for the git dir. Return None if the git dir
    cannot be found or if git is not installed.

    Only import sphinx during hook processing

    When pbr is imported to handle writing the egg_info file because of
    the entry point, it's causing sphinx to get imported. This has a
    cascading effect once docutils is trying to be installed on a
    system with pbr installed. If some of the imports fail along the way,
    allow pbr to continue usefully but without the Sphinx extensions
    available. Eventually, when everything is installed, those extensions
    will work again when the commands for build_sphinx, etc. are run
    separately.

    Also slip in a change to reorder the default list of environments run by
    tox so the testr database is created using a dbm format available to all
    python versions.
