Weston RDP on ARM

[Heikki Sarkanen]

I tried without FreeScale pathces which unfortunately doesn't make a
difference with the headless RDP (obviously I cannot use fbdev backend
without those pathces). There might still be some build options:
https://github.com/hsarkanen/poky/blob/wayland_1.7.0/meta/recipes-graphics/wayland/weston_1.7.0.bb#L23-L32
and https://github.com/hsarkanen/meta-fsl-arm/blob/wayland_1.7.0/recipes-graphics/wayland/weston_%25.bbappend#L8-L35
which makes our Weston builds different. Also I don't currently have
proper X86 HW to test with so it may be the ARM also.

I tried all the different approaches with RDP to test if it works on
my iMX6 system. My ultimate goal is to run a compositor on
fbdev-backend and copy the same screen over RDP, similar to x11vnc. So
if you or someone could answer the first question: "How can I show
desktop-shell contents running on fbdev-backend on this fullscreen
shell compositor?" it would be really helpful.

Thanks for the help!

BR,
Heikki Sarkanen
