Christophe CURIS fd47650717 WUtil: New macro 'wlengthof' in the public API to get number of elements in an array ...

The new macro 'wlengthof' returns the number of elements for which a local
array have been defined, which makes code easier to read than the
previous [sizeof() / sizeof([0]) ] construct.

The macro includes a static assertion to stop compilation if it is being
used on a pointer, for which we cannot know the size of the array, to
avoid generating dummy result. This can work only with C11 which
standardised the static assertions.
