pthreads: Add pthread_is_threaded_np() function.

pthreads: Enhance pthread_sigprocmask() stub.

Some ports expect this function to work even before pthread_create().

pthreads: Add pthread_getattr_np().

pthreads: Reimplement pthread types using non polluting types.

Use __ implementation specific namespace and adjust libthread_xu.
* The pthread_addr_t type was specific only to libc_r, remove it.

pthreads: Reimplement pthread types using non polluting types.

Use __ implementation specific namespace and adjust libthread_xu.
* The pthread_addr_t type was specific only to libc_r, remove it.
* The pthread_startroutine_t typedef was never used since initial fork.
* The mutex member in struct pthread_once was for libc_r only, rename
it to __sparelibc_r void pointer to keep ABI compatibility.
* Mangle struct names using __type_s scheme to avoid collisions with
user defined types in 3rd-party software packages.
* Adjust partly publicly visible struct pthread_once members too.

libc: Make the signal name array uppercase.

This is to satisfy POSIX which requires that the string printed by
'kill -l <signal number>' shall be the name of the symbolic constant
(for example, SIGKILL) without the 'SIG' part.

This also fixes a number of sh(1) tests.

While here, sync a bit further with FreeBSD. Specifically, use
C99 designated initialization.

kernel - Add PROC_PDEATHSIG_CTL and PROC_PDEATHSIG_STATUS

* Add PROC_PDEATHSIG_CTL and PROC_PDEATHSIG_STATUS to procctl(2).

This follows the linux and freebsd semantics, however it should be noted
that since the child of a fork() clears the setting, these semantics have
a fork/exit race between an exiting parent and a child which has not
yet setup its death wish.

* Also fix a number of signal ranging checks.
