Readers share the lock while no writer holds it and a writer waits until it is free. Destroying a held or waited-on lock and destroying the waiting-queue pool of a lock a thread waits on return ULT_ERROR_BUSY, and sceUltFinalize wakes waiters with ULT_ERROR_STATE, as for the mutex.
Forwards _sceUltWaitingQueueResourcePoolCreate and _sceUltSemaphoreCreate to the existing calls, like the other underscore Ult exports. Declares sceNetShowIfconfig, sceNpWebApi2GetMemoryPoolStats, Json::Value::setNullAccessCallBack, kqueue, kevent and one pad call of unknown name without an implementation.

sceUltFinalize cleared gUlthreads directly, dropping the last
shared_ptr to an UltUlthreadState while its worker thread still held
the raw pointer passed to scePthreadCreate. Finalize now returns
ULT_ERROR_BUSY when an ulthread is still registered, before any global
state is torn down, following the BUSY convention of the queue,
semaphore and queue data pool destroy paths. Joining the ulthread
remains the caller's responsibility, as sceUltUlthreadJoin already
keeps the state alive across scePthreadJoin and erases it afterwards.
