Implement shm drivers. Planned drivers are noop, dmabuf and virtwl. - virtwl will be used by default if /dev/wl0 exists. - dmabuf will be used by default if drm device was specified. Specific driver can be forced using --shm-driver flag and XWL_SHM_DRIVER variable. Noop driver will just forward shm segments to host compositor. Virtwl and dmabuf driver will allocate shadow buffers and copy damaged areas into these buffers.
