Remove <sys/semaphore.h> so that we have <semaphore.h> only.

There is no point for us to go through the kernel for getting at
SEM_VALUE_MAX from sysconf(3), so return it directly and remove
the associated p1003_1b.sem_value_max sysctl.

Beyond that, the kernel didn't need this header. I've found no
ports that need it, either.

For safety, bump __DragonFly_version anyway.

sysconf(3): Fix _SC_GET{GR,PW}_R_SIZE_MAX.

The standard allows to return -1 if there is no hard limit on the size
of the buffers.

<unistd.h>: Add _POSIX_THREAD_ROBUST_PRIO_{INHERIT,PROTECT} definitions.

Also adjust sysconf(3) and getconf(1) accordingly.

libc/sysconf: Simplify sysconf(_SC_XOPEN_SHM) a bit.

We never had sysv_shm as a module like FreeBSD, only as a kernel
option (SYSVSHM), which was made a no-op when we started to compile
it into our kernels by default over a year ago (see 10ceb70237a5).

The sysctl check in the sysconf(3) code was only there to check if
it was compiled into the kernel or (in FreeBSD's case) if it was
loaded as a module, when it was still optional.

So the worst thing that could happen after this commit is a wrong
return value for sysconf(_SC_XOPEN_SHM) if someone was running a
kernel without "options SYSVSHM" from earlier than July 29, 2014
in combination with a current world. This all looks quite unlikely,
so remove the check.

Also, return the right variable from <unistd.h>.

mqueues: Let the world know we support them.

There are two ways to determine whether we support the message
passing interface, as described in POSIX 1003.1B standard.

The standard way is to use sysconf(3) and the DragonFly-specific
way is to check the value of p1003_1b.message_passing sysctl.

We make sure that both return consistent results with respect to
each other.

Add _SC_NPROCESSORS_CONF and _SC_NPROCESSORS_ONLN variables to the
sysconf(3). These are nonstandard, but implemented in many systems.

Cleanup:

- Add $DragonFly$.
- Ansify function definitions.
- Remove (void) casts for discarded return values.
- In function definitions, move the type on a line of its own.
- Remove __P.

Define IOV_MAX for userland too and make it available via sysctl and
getconf/sysconf. This is kind of a hack, but too much code wants it.

Add the DragonFly cvs id and perform general cleanups on cvs/rcs/sccs ids. Most
ids have been removed from !lint sections and moved into comment sections.
