convert: add support to detect git renames and copies
Git is fairly unique among VCSes in that it doesn't record copies and renames,
instead choosing to detect them on the fly. Since Mercurial expects copies and
renames to be recorded, it can be valuable to preserve this history while
converting a Git repository to Mercurial. This patch adds a new convert option,
called 'convert.git.similarity', which determines how similar files must be to
be treated as renames or copies.
