Major updates to perl scripts

Add new git backend in VCS_git.pm

Switch from an old-style set of function calls to an OO API. This
allows for initialisation and some state to be kept in the VCS_git.pm
module - namely a per-file cache of commit hashes for a massive
performance boost when doing lots of lookups.

Extend the API with 2 new utility functions:
 * get_oldest_revision()
 * next_revision()

Extended the vcs_cmp_rev() function to take a filename too.

Add a test harness to validate the git and cvs backends.

Add switch_to_git_translations.pl to walk the tree and switch from cvs
revisions to git commit hashes in translation-check headers.

Change all of our local scripts to use the new Local::VCS frontend
*where it makes sense*. Some scripts will behave slightly differently,
as the new world can't exactly match the old behaviour.
