Fix change to prevent cancel signal in unsafe places.
The bits tested to decide when to delay the return when switching
off async cancel mode were wrong. Fix that. Also close a race
condition in pthread_cancel where the bit indicating the cancellation
is unconditionally set even if the cancel type might have changed.
