The sRGB display uses a power-2.2 transfer characteristic. These enum
values refer to the two-piece sRGB transfer function instead, so they
should not be named "EOTF".

Add a status return value to every test definition. There are no
behavioral changes, previously the RESULT_OK was simply assumed.
The benefit of this is that in the future individual tests can also
return RESULT_SKIP, so that we can keep statistics of skipped tests.
ivi-layout-internal-test.c has the only case where a test function may
return early. That one is set to return RESULT_HARD_ERROR to match the
compositor exit code already there.
Also documentation is updated.

This commit gets rid of libc's abort() usage in the test suite using
test asserts instead.
Asserts run in the server as plugins aren't converted because they are
shared between server and client.

This adds a new test helper library that depends on LittleCMS 2.
For starters, the library implements conversion from enum transfer_fn to
ICC multiProcessingElements compatible LittleCMS curve object.
That conversion allows encoding transfer funtions in ICC files and
LittleCMS pipelines with full float32 precision instead of forcing a
conversion to a 1D LUT which for power-type curves is surprisingly
imprecise.
This also adds CI tests to make sure the conversion matches our
hand-coded transfer functions.
