drisw: Try harder to probe whether MIT-SHM works
XQueryExtension merely tells you whether the extension exists, it
doesn't tell you whether you're local enough for it to work.
XShmQueryVersion is not enough to discover this either, you need to
provoke the server to do actual work, and if it thinks you're remote it
will throw BadRequest at you. So send an invalid ShmDetach and use the
error code to distinguish local from remote.
[airlied: fixed bug not resetting xshm_error to 0 on success,
which made later stuff fail completely.]
