Add experimental support for process descriptors
A "process descriptor" file descriptor is used to manage processes without using the PID namespace. This is required for Capsicum's Capability Mode, where the PID namespace is unavailable.
New system calls pdfork(2) and pdkill(2) offer the functional equivalents of fork(2) and kill(2). pdgetpid(2) allows querying the PID of the remote process for debugging purposes. The currently-unimplemented pdwait(2) will, in the future, allow querying rusage/exit status. In the interim, poll(2) may be used to check (and wait for) process termination.
When a process is referenced by a process descriptor, it does not issue SIGCHLD to the parent, making it suitable for use in libraries---a common scenario when using library compartmentalisation from within large applications (such as web browsers). Some observers may note a similarity to Mach task ports; process descriptors provide a subset of this behaviour, but in a UNIX style.
This feature is enabled by "options PROCDESC", but as with several other Capsicum kernel features, is not enabled by default in GENERIC 9.0.

Document why HOST_NAME_MAX (and hopefully other similar constants in the future) is not defined.
Define in <sys/unistd.h> all 1003.1-2001 option and option group constants which did not meet the standard for inclusion in <unistd.h>. Delete from <sys/unistd.h> all sysconf(3) constants and those option constants which were moved to <unistd.h>. pathconf(3) keys remain here as pathconf() is implemented directly as a system call. Add a comment noting brokenness in some .1e additions here. Fix whitespace in definition of constants for rfork().

Major update to the way synchronization is done in the kernel. Highlights include:
* Mutual exclusion is used instead of spl*(). See mutex(9). (Note: The alpha port is still in transition and currently uses both.)
* Per-CPU idle processes.
* Interrupts are run in their own separate kernel threads and can be preempted (i386 only).

Move POSIX feature constants from pthread.h to unistd.h, as required by 1003.1c-1995.
Undefine _POSIX_THREAD_SAFE_FUNCTIONS, since we do not implement all of the necessary interfaces. At least getgrgid_r(), getrnam_r(), getpwuid_r(), getpwnam_r(), getc_unlocked(), getchar_unlocked(), putc_unlocked(), and putchar_unlocked() are missing. Due to a likely typo in 1003.1c-1995, we are not technically allowed to define _POSIX_THREADS without defining _POSIX_THREAD_SAFE_FUNCTIONS, but either way we're non-compliant, so I'm leaving _POSIX_THREADS defined.

Changes to the LINUX_THREADS support to only allocate extra memory for shared signal handling when there is shared signal handling being used.
This removes the main objection to making the shared signal handling a standard ability in rfork() and friends and 'unconditionalising' this code. (i.e. the allocation of an extra 328 bytes per process).
Signal handling information remains in the U area until such a time as it's reference count would be incremented to > 1. At that point a new struct is malloc'd and maintained in KVM so that it can be shared between the processes (threads) using it.
A function to check the reference count and move the struct back to the U area when it drops back to 1 is also supplied. Signal information is therefore now swapable for all processes that are not sharing that information with other processes. THis should addres the concerns raised by Garrett and others.

Changes to support building with _POSIX_SOURCE set to 199309L:
1. Add sys/_posix.h to handle those preprocessor defs that POSIX says have effects when defined before including any header files;
2. Change POSIX4_VISIBLE back to _POSIX4_VISIBLE
3. Add _POSIX4_VISIBLE_HISTORICALLY for pre-existing BSD features now defined in POSIX. These show up when:
_POSIX_SOURCE and _POSIX_C_SOURCE are not set or _POSIX_C_SOURCE is set >= 199309L
and vanish when:
_POSIX_SOURCE is set or _POSIX_C_SOURCE is < 199309L.
4. Explain these in man 9 posix4;
