by Vadim Yanitskiyutils: use built-in static_assert() if available
Static assertion is part of the C language since C11. It produces
more readable [user supplied] error messages than:
error: size of array ‘dummy_foo_bar’ is negative
and is generally smarter than the current osmo_static_assert()
implementation as it would fail when non-constant expression is
given, whereas osmo_static_assert() would have no effect at all.
