The majority of KMS devices support pre-multiplied encoded framebuffers.
But a few of them don't. This adds support for such devices.
In-shader blending is required for this, and it shouldn't work on
devices that don't support it. For now this works only with the
GL-renderer.
Note: this should never work with test quirks

The paint_node life cycle should match the output's, so we should be able

We already validate the paint node list in weston_output_repaint,
immediately after we conditionally rebuild the z_order_list.
These asserts are thus completely redundant, as we've already
performed them in the front end.
My reason for removing this now is to drop weston_view usage
from the backend.

Backends work on paint nodes, not views - and the paint node internal
name is a superset of the view internal name anyway, so it's not hard to
figure out which view a paint node belongs to when reading debug text.

The failure reason is already part of the paint node, so passing the view

Backends should be relying on paint nodes for their information, not
views.
Since we always have a paint node when we want to pass a buffer, we can
pass that instead of a view.

This avoids ICC paths when no ICC profiles are explicitly used.
We can simplify the profile information sending and use the generic path
for the stock profile as well, no longer hard-coding the stock profile
in two places.
Since the stock profile creation cannot fail, we can streamline
cmlcms_init() a little, too.

The icc<->parametric color transformation code uses "optical ICC
profiles" as part of the ICC pipeline. These profiles use a linear TRC
to encode the black point. When such TRC survives all optimizations, it
will cause the 3D LUT fallback path to be taken.
Detect such curve sets on the ICC pipeline optimizer, and convert them
to matrix stages. The matrix stages will then be optimized as usual,
often eliminating the stage completely.
The results can be seen in color-icc-output test after the stock sRGB
profile has been changed into a parametric one, causing all cases in the
test to hit the parametric-to-icc path. Some tests fail when they
suddenly start using the 3D LUT path which causes the errors to rise.
This patch fixes those (future) cases, and the errors remain the same as
before changing the stock profile.

Assertions are the usual way of failing tests in the compositor code,
but it means the test program cannot continue further. It would be
better to save an error exit code and run the compositor to the finish,
and then continue with the next test fixture.
I want to force some paths in GL-renderer output initialization for a
test, and fail otherwise. Calling weston_compositor_exit_with_code()
crashes there though, because the frontend has not installed the exit
handler yet.
Skip the exit handler if it's not there. The error exit code is still
saved, and will eventually bubble out of the compositor.
While at it, let's document these.

This creates the fragment shader state needed for in-shader blending.
In-shader blending is always enabled if supported:
- GL supports the necessary features, and
- the blend-to-output color curve is exactly invertible.
The exact inverse is required, because the compositor will do repeated
decode-encode cycles per destination pixel, one for each non-opaque
source. Roundtrip errors through decode-encode might accumulate
otherwise. For now, identity, enumerated, and parametric curves are
deemed invertible while LUT is rejected without inspection.
Therefore to make use of this feature, outputs need to be configured with
a non-LUT type EOTF/TRC.
In-shader blending is always enabled, because it should be universally
more efficient than the use of a shadow buffer.
This feature was originally drafted for Weston by Sebastian Wick.
