Change the meaning of counter in fibril mutex

Previously analogous to semaphore tokens, initially 1 and
counting downward into negative numbers.

Now the number of fibrils currently accessing or waiting for access
to the critical sections. Initially 0 (unlocked mutex), and counting
up. Never negative when used correctly. Also consistent with
readers/writers counts in rwlock.

This way is IMO easier to understand.
