Helper to assert that a value does not have any bit set outside of the
mask. To be used with "all bits mask" of enum types that enumerate bits.

Currently in translate_curve_element() we always translate the curve
into a LUT. But in the future we'll be able to translate the curves to
parametric ones.
So move the current code to a new function
translate_curve_element_LUT(), so that in translate_curve_element() we
are able to call one of the two functions (_LUT() or _parametric()).
No behavior changes, just preparation for the upcoming patches.

Not a behavior change, but this allow us to decide what function pointer
to use within this function (instead of forcing callers to decide that).
In the following commits this will be helpful. We'll add more curves
besides 3x1D LUT's and, depending on the curve, the function pointer
signature may differ.
Also, we now pass the xform directly to the function, and it can select
the curves depending if it is being called for a pre or a post curve.

When we are destroying the color manager, the components referencing
color profiles should have already been destroyed. We have an assert
in cmnoop_destroy() to make sure that the stock profile has refcount
equal to 1.
But we currently have an issue in Weston. While shutting down with
client surfaces alive, we may leak them. So we try to destroy
the color manager with surfaces still alive, and they may be
referencing color profiles.
We already have a workaround for this in our LittleCMS color plugin,
but we've missed that in color-noop. This fixes that, so now we don't
hit the assert anymore.
As we are already dealing with asserts in color-noop, I took the
liberty to replace the last usage of assert with our own wrapper
in this file.

In this MR we add support to the majority of the interfaces from the
color-management protocol.
That means that we are able to advertise output's images descriptions to
clients, preferred surface images descriptions, and so on. We also
support clients that wants to create ICC-based images descriptions and
set such descriptions for surfaces.
We still don't support the interface to allow clients to create
image descriptions from parameters, but that should be addressed
in the near future.

This is preparation for the CM&HDR protocol implementation. It requires
us to give a unique id to each color-profile, so let's do that.
In this commit we introduce a generic id generator to libweston, and
its first user: the color-profile.

We forgot to include stdbool to weston-assert.h, but this was not
causing issues because callers of weston_assert_true() themselves
include stdbool.
Add stdbool to weston-assert, as this is the right thing to do.

Add yet another flavor of assertion macros.
Unlike libc assert.h assert(), these cannot be easily disabled by the
build. They also print both the implied expression and the compared
values.
Unlike ZUC macros, there is much less framework code and it can handle
also floating-point types.
The function custom_assert_fail_ can be redefined, meaning that
different compilation units can do different things on failure.
Also the 'compositor' parameter was added to the new macros because we
plan to use these asserts in our log infrastructure, and we want to
print the "failure" messages in the right log scopes. Having the
compositor already in the macros will avoid double work.
Another future possibility is to write specific asserts for the test
suite. So we would be able to write a test suite failure function that
just print what "failed" without aborting.
There is also limited support for custom types.
These are actually pretty similar to libinput's litest macros.
