Axel Dörfler 34e92cad76 Added and implemented new system calls switch_sem() and switch_sem_etc(); even if
they are public now, they might become private later on.
It's almost the same as acquire_sem() but allows you to release another semaphore
atomically. This makes condvar implementations and the like very simple to do.
Added B_CHECK_PERMISSION flags to the user calls, although it's not honored yet.
