sparse does not understand -fshort-wchar. Default to using uint16_t
as a wchar_t if not explicitly specified by the compiler, to avoid
large numbers of spurious warnings from sparse.

sparse does not define __WCHAR_TYPE__ or __WINT_TYPE__. We already
define __WCHAR_TYPE__ if the compiler does not do so; do the same for
__WINT_TYPE__.

Some newer versions of gcc (observed with a patched gcc 4.5.1) seem to
treat our offsetof() implementation as not being a compile-time
constant. Fix by using __builtin_offsetof() when available. (As with
the original offsetof() macro, this code is copied from the Linux
kernel's stddef.h.)
