Remove sigreturn declaration and the now-unused libc syscall stub

Convert sigemptyset and sigfillset to inline functions to avoid
warnings with newer gcc versions and -Werror=unused-value.

Split the intra-thread functionality from kill(2) into its own syscall
thrkill(2), rolling the kill(2) syscall number with the ABI change to
avoid breaking binaries during during the transition. thrkill(2) includes
a 'tcb' argument that eliminates the need for locking in pthread_kill()
and simplifies pthread_cancel(). Switch __stack_smash_handler() to use
thrkill(2) and explicitly unblock SIGABRT.

Minor bump to both libc and libpthread: make sure you install a new kernel!

Welcome to 1989: assume the compiler support const

lint is dead (long live the lint!), so stop using it as a cpp conditional
(namespace pollution!) or talking about its opinion on code.

functions are top-level objects anyways, make that clearer.

The prototype for pthread_sigmask(2) is supposed to live in <signal.h>
instead of <pthread.h>.

ok guenther@, millert@

sigstack() is long dead, and the compat sigaltstack syscall is gone too.
Correct the namespace protections for sigreturn(), sigwait(), and psignal()

ok millert@

sigset_t is unsigned, so eliminate a warning by shifting a 1U instead
of a 1 when creating signal masks.

ok millert@

Now that __only_inline is in <sys/cdefs.h>, replace the local versions in
<ctype.h> and <signal.h>

ok kettenis@ millert@ deraadt@

Always force GNU inline semantics here as well.

Make sure sys_signame and sys_siglist are wrapped in __BEGIN_DECLS.
Needed to tell pedantic C++ compilers these symbols have 'C' linkage.

allow extern inline stuff to proceed unchanged thru the mess that the
combined GCC and ISO committees managed to make out of it.

With this, gcc >= 4.3 can grok its way through it correctly.

Do not declare errno as extern int, set it via __errno().

First step in include files overhaul. Use __FOO_VISIBLE (as defined
in sys/cdefs.h) instead of _FOO_SOURCE. Also fix several namespace
pollution issues, including the byte order defines. OK deraad
