Process a lot of feedback from bde@ on <sys/cdefs.h>:

- Add __alignof() for non-GCC and GCC < 2.95.
- Simply implement the C1X keywords on top of the existing __macros.
- Add struct __hack to _Static_assert to require consumers to add a
  semicolon.
- Add an extra underscore to __assert_ to allow it to be combined with
  locally defined versions of CTASSERT in the tree.
- Add proper casts to __offsetof() to make it work for cases where
  sizeof(size_t) != sizeof(uintptr_t).
- Globally replace size_t and uintptr_t by __size_t and __uintptr_t.
  This removes the dependency on <sys/types.h> / <stdint.h>. Practically
  any header file ends up including <machines/_types.h> somehow.
- Change argument names of macros to match with the rest of the file.
