Sreerenj Balachandran c803ca4af5 wayland: More fixes based on wayland-0.95.0 and gstreamer-1.0 apis
- bump wayland version to 0.95.0 which will lead to stable 1.0 release
- avoid memcopy and use propose_allocation for GstBufferPool allocation
- using WaylandBufferPool
- shm: Allocate shm buffers through new wl_shm_pool interface
  (the shm buffer allocation is a two step process now: first
  allocate a wl_shm_pool, then allocate a buffer from the pool)
