csjp 17aca298fa Add much needed descriptions for a number of the IPC related sysctl OIDs. 
This information will be very useful for people who are tuning applications
which have a dependence on IPC mechanisms.

The following OIDs were documented:

Message queues:
 kern.ipc.msgmax
 kern.ipc.msgmni
 kern.ipc.msgmnb
 kern.ipc.msgtlq
 kern.ipc.msgssz
 kern.ipc.msgseg

Semaphores:
 kern.ipc.semmap
 kern.ipc.semmni
 kern.ipc.semmns
 kern.ipc.semmnu
 kern.ipc.semmsl
 kern.ipc.semopm
 kern.ipc.semume
 kern.ipc.semusz
 kern.ipc.semvmx
 kern.ipc.semaem

Shared memory:
 kern.ipc.shmmax
 kern.ipc.shmmin
 kern.ipc.shmmni
 kern.ipc.shmseg
 kern.ipc.shmall
 kern.ipc.shm_use_phys
 kern.ipc.shm_allow_removed
 kern.ipc.shmsegs

These new descriptions can be viewed using sysctl -d
