Seems to be legacy remnant for no longer required pthread_kill() and

<pthread.h>: Fix typo: __restict -> __restrict.

Reported-by: zrj

<pthread.h>: Add missing 'const' to four functions.

Add missing restrict qualifiers in POSIX function definitions/declarations.

This creates no further -Wrestrict warnings with gcc80 in buildworld.

libthread_xu: Fix issues detected by gcc80.

The changes to <pthread.h> all deal with -Wnonnull-compare warnings,
which are issued when a function has a NULL check for a parameter that
at the same time is marked with __attribute__((nonnull(...))), aka
__nonnull(...).

Such __nonnull() decoration only ever catches those cases where NULL is
passed directly to the function, but not any more indirect ways. What
makes matters worse is that in higher optimization levels (-O >= 2),
GCC will happily optimize out any NULL checks within the function for
these parameters.

This means that __nonnull() is generally inferior to a direct NULL check
in the function itself and if we have both, which newer GCCs warn about
with -Wnonnull-compare (that is part of -Wall), we should remove the
__nonnull().

This commit does that for all parameters which our libthread_xu checks
directly in the function. What remains are __nonnull() for parameters
which are _not_ checked in the functions, to at least catch cases where
NULL is passed directly. We should think about adding real checks for
those parameters too.

While here, add a "/* FALLTHROUGH */" comment in thr_printf.c which
fixes a -Wimplicit-fallthrough warning.
