a3cc62c285 cogl tests: Force defined behaviour for 24-bit left-shifts
When r is 128 or more, running tests compiled with the undefined behaviour
sanitizer (ubsan) reports:

test-utils.c:312:45: runtime error: left shift of 128 by 24 places cannot be represented in type 'int'

which indeed it cannot. Force the type to be unsigned 32-bit so that we
get defined behaviour.

Similarly, in test-atlas-migration, the left-shifted guint8 is promoted
to int, which again does not have enough non-sign bits available to
left-shift a value >= 128 by 24 bits. Again, force the shift to be done
in unsigned 32-bit space.

This was originally cogl!22, but applies equally to mutter's fork of cogl.

982d135ace cogl: Add missing function declarations
In plenty of places a non-static function was defined but didn't have
the corresponding declaration. Fix this by adding them, or alternatively
making them static.
