  Bring <sys/cdefs.h> in sync with FreeBSD HEAD:

  - Add an __alignof() for non-GCC and GCC < 2.95.
  - Attempt to implement the following C11 keywords: _Alignas(),
    _Alignof(), _Noreturn, _Static_assert() and _Thread_local.
  - Add __generic(), which allows us to do _Generic() in a portable
    fashion.
  - Improve __offsetof(), __DECONST(), __DEVOLATILE() and __DEQUALIFY()
    to use __uintptr_t and __size_t to make them work with less
    header prerequisites.
  - Add __has_feature(), __has_include() and __has_builtin() to make it
    easier to test against Clang features.

Tested by:	linimon@'s exp-run (thanks!)
