Add Semaphore#to_mtx returning an unchecked mutex-like facade
...
Because there is a very significant performance hit for using the
mutex implementation, which correctly checks ownership, this
implementation formalizes treating a raw semaphore as a faster,
unchecked implementation of mutex.

Fix ConditionVariable#signal to only post if semaphore has waiters
...
This fixes a bug where calls to #signal would end up "over-posting"
the semaphore, causing subsequent waits to return immediately until
the semaphore value is back down to zero.
