[RFC v2 0/3] xwayland: Add support for eglstreams

[Lyude Paul]

Some changes:
 - I broke GBM by accident in v1 by not making sure that we setup wl_drm
   in xwl_glamor_gbm_init_wl_registry() by incrementing
   xwl_screen->expecting_event in xwl_glamor_gbm_init_wl_registry()
   properly and decrementing it in the wl_drm handlers. So now we don't
   break that.
 - Fixed up the commit message for adding EGLStreams in response to
   ajax's comments

As well, like ajax asked here's some benchmarks of how well this works:

(keep in mind, nouveau is at max pstate here since otherwise it performs
terribly)

1: nouveau-gbm.log
2: nouveau-shm.log
3: nv-eglstream.log
4: nv-shm.log

     1         2         3         4    Operation
--------  --------  --------  --------  ---------
 63800.0   23500.0   27600.0   27100.0  Copy 500x500 from pixmap to window

Unfortunately, not that great :(
