(Split from MR !319 (merged))
This adds a static (built-time) assertion that the length of given choice list value and label arrays are of equal length.
This happens to impose a new constraint to the two macros this is applied to - you now cannot use
extern variables for the arrays. This is because of the language limitation that
sizeof() cannot be used with them.
One in-tree module needed an
extern variable fix as a result of this constraint, as done in the first commit.
The value of this check must be weighted against this constraint - do we care about supporting modules being able to use
extern arrays for these macros; does it cause a problem for anything.
