Passing the backend as a parameter to the weston_backend function
pointers seems more natural and will be very useful once there can be
more than one backend.
Since all backends already store a pointer to the compositor instance,
replace the compositor parameter with the backend in all functions.

The previous version used div() to separate the column and row of the
current element, but that function is implemented as a libc call, which
prevented the compiler from vectorising the loop and made matrix
multiplication appear quite high in profiles.
With div() removed, we are down from 64 calls to vfmadd132ss acting on
one float at a time, to just 8 calls to vfmadd132ps when compiled with
AVX2 support (or 16 mulps, 16 addps with SSE2 support only), and the
function isn’t a hot spot any more.

This is an odd corner case where the surface doesn't yet have an output
assigned -- noticed when starting up with the RDP backend and
fullscreen-shell, and we attempt to emit a timeline point for a surface
without an output assigned, causing weston to crash when that
happens.
Rather than trying to catch this in the timeline code, still emit the
flush damage timeline but instead of using the output the surface is on,
use the output that accumulates damage.

This sets up monitor layout callbacks, and enables input event translation
between the RDP space and the weston desktop. The RDP backend now uses
a heads changed callback instead of the simple head configurator.
We only allow a single monitor for now, but in the future RAIL will make
use of multi-head.
As a side effect, scaling is now supported in RDP sessions.
It should be noted that due to differences between RDP and wayland
representation of their global coordinate spaces, mixing DPI leads to
RDP monitor layouts that can't properly be represented in weston.

Unfortunately the legacy ioctl does not offer any way to reset the LUT
without actually crafting an identity LUT.
If the legacy gamma libdrm function indicates the feature is not
supported, do not try to use it again. This avoids hammering the legacy
gamma every frame when deprecated drm_output_set_gamma() is not used.
drm_output_set_gamma() is not updated to check/set this flag in order to
maintain its old behavior.
