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.

Fix the RDP backend to handle to_rdp_head() returning NULL.

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.

We are assuming that gamma LUT is pass-through, so better ensure it

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.

We are assuming that CRTC_GAMMA_LUT is pass-through, so better ensure it
really is pass-through rather than whatever the previous KMS client left
there.
Unfortunately, we have old drm_output_set_gamma() API that cms-static
and cms-colord plugins are using. To avoid trampling over them, do not
touch gamma after they did. Those plugins are deprecated, so there is no
reason to make set_gamma work through atomic.
drm_output_set_gamma() is called from weston_compositor_add_output()
through the output_created_signal. This is after drm_output_enable() and
before any KMS modeset or atomic commit on the CRTC. Therefore it is not
possible that there would be any KMS action in flight when
drm_output_set_gamma() is called, and so setting deprecated_gamma_is_set
should be non-racy - like setting CRTC_GAMMA_LUT itself.

Move the debug printing before the bail-out if the property does not
exist. This means that trying to set a missing property will be logged,
and it can be identified by the property id being 0.
We are starting to program more KMS properties, and if KMS state
building fails, this gives better chances to figure out what happened.
For example, if we accidentally assume that some property always exists
when it doesn't.

Similar to the backend type, also expose the renderer type enum as ABI.
This makes it possible to implement a more consistent config API, as
opposed to every backend hand-rolling its own use-the-other-one bool.
The enums are explicitly numbered to avoid 0, so 0 can be used as a
'not-specified' sentinel value to allow backwards compatibility with the
old config interfaces.
