Subject: g3dvl: Add Nouveau winsys, libdriclient.

Nouveau winsys is based on Mesa's Nouveau winsys and soft-links to most of
it. The 'nouveau_context' and 'nouveau_screen' code contains most of the
changes, 'nouveau_winsys_pipe', 'nouveau_swapbuffers' and 'nouveau_lock'
contain some minor changes. The driclient library contains the DRI
userland stuff, most of which was based on Mesa's DRI code.
