Move a backwards compatibility wrapper for svnserve versions 1.0-1.1 to the ra layer. This will make the ra layer easier to use and maintain. (Callers can stop worrying about this limitation in old svnserve versions)
We can't really move this in ra_svn as within ra_svn we can't use the normal ra apis.
Remove some unnecessary work from from our "ls" code.
* subversion/libsvn_client/list.c (get_dir_contents): don't attempt to match locks when there are none
* subversion/libsvn_ra_svn/client.c (ra_svn_get_dir): according to the protocol spec, we send the name of the dirents (i.e. 1 segment) -- never a multi- segment relpath. There is nothing to canonicalize.
