Not really connected to resolving this issue, but I think this ra api can be optimized a bit further with the knowledge we build with the wc-ng code.

Currently the locks are always returned as full filesystem paths (in '/trunk/path/to/file' style) instead of as a session relative path (e.g. path/to/file). Switching to session relative paths would allow using the svn_relpath_*() apis on the files and would (slightly) reduce the amount of traffic.

In combination with this change we don't even need feature negotiation: On the client it will be easy to detect which style of paths is returned by just checking if the first path starts with a '/'. The server can switch to relative paths when a depth is passed on the request.
