git-svn: reinstate old rev_db optimization in new rev_map
This reinstates an old optimization in .rev_db which
stored the highest revision number we scanned, allowing
us to avoid scanning the SVN log for those revisions
again in a subsequent invocation.
This means the last 24-byte record in a .rev_map file
can be a 4-byte SVN revision number with 20-bytes of
zeroes representing a non-existent commit. This record
can and will be overwritten when a new commit iff
the commit is all zeroes.
