Waiman Long 8c81ddd2ac ipc: IPCMNI limit check for semmni
For SysV semaphores, the semmni value is the last part of the 4-element
sem number array.  To make semmni behave in a similar way to msgmni and
shmmni, we can't directly use the _minmax handler.  Instead, a special sem
specific handler is added to check the last argument to make sure that it
is limited to the [0, IPCMNI] range.  An error will be returned if this is
not the case.
