POSIX Semaphores

[Paul Goyette <paul%whooppee.com@localhost>]

According to the man page sem(4), one needs to include "options 
P1003_1B_SEMAPHORE" in the kernel config file in order to support this 
feature.  Yet, the file kern/uipc_sem.c is included unconditionally in 
all kernels, and there appears to be nothing in NetBSD anywhere that 
depends on P1003_1B_SEMAPHORE.

Most of the MODULAR-ization work has already been done (with only the 
actual building of the loadable module left), so I would like to propose 
that this feature be made conditional, as described in sem(4).

Any comments?  Is P1003_1B_SEMAPHORE the best name for the kernel 
option, or would POSIX_SEMAPHORES be better, or some other option name? 
Should the module be made auto-loadable?

On a related topic, since sem is not actually a device driver, it does 
not seem appropriate that its man page belongs in section 4.  Wouldn't 
it be more correct for this man page to reside in section 7?
