Daniel Stone 4b8b60ebfd remoting: Use DRM FourCC formats instead of GBM formats 
The remoting plugin currently has a set_gbm_format() hook, which accepts
GBM_FORMAT_* tokens from the host to set as a supported format.
GBM_FORMAT_* values are strictly aliased with DRM_FORMAT_*.

In order to avoid an extra unnecessary dependency from the remoting
plugin on GBM, switch to using the formats from libdrm instead.

This fixes a compile error seen when the remoting plugin is enabled:

    ../remoting/remoting-plugin.c:39:10: fatal error: gbm.h: No such file or directory
       39 | #include <gbm.h>
          |          ^~~~~~~
    compilation terminated.

The error was caused by not having any dependency at all on GBM from
the remoting backend, which is fixed here by adding a new dependency on
the libdrm headers for drm_fourcc.h.

	Remoting plugin for Weston


The Remoting plugin creates a streaming image of a virtual output and transmits
it to a remote host. It is currently only supported on the drm-backend. Virtual
outputs are created and configured by adding a remote-output section to
weston.ini. See man weston-drm(7) for configuration details. This plugin is
loaded automatically if any remote-output sections are present.

This plugin sends motion jpeg images to a client via RTP using gstreamer, and
so requires gstreamer-1.0. This plugin starts sending images immediately when
weston is run, and keeps sending them until weston shuts down. The image stream
can be received by any appropriately configured RTP client, but a sample
gstreamer RTP client script can be found at doc/scripts/remoting-client-receive.bash.

Script usage:
	remoting-client-receive.bash <PORT NUMBER>


How to compile
---------------
Set --enable-remoting=true when configuring weston. The remoting-plugin.so
module is created and installed in the libweston path.


How to configure weston.ini
----------------------------
See man weston-drm(7).
