sceKernelCancelSema was a throwing stub. It now releases every thread
blocked in sceKernelWaitSema with SCE_KERNEL_ERROR_ECANCELED without
consuming tokens, sets the count to setCount (the initial count when
setCount is negative) and reports how many threads were waiting. A
setCount above the maximum returns SCE_KERNEL_ERROR_EINVAL and changes
nothing.
Waiters are counted separately from waiterCount, which is only
decremented when a waiter leaves, so two cancels in a row do not report
the same thread twice.
