git-svn: correctly handle globs with a right-hand-side path component
Several bugs were found and fixed while getting this to work: * Remember the 'R'(eplace) case of actions and treat it like we would an 'A'(dd) case. * Fix a small case of follow-parent missing a parent if a subdirectory was modified in the revision where the parent was copied. * dirents returned by get_dir sometimes expire if the data structure is too big and the pool is destroyed, so we cache get_dir (along with check_path and get_revprops) temporarily along with its pool.
