Add support for dynamically created and destroyed mutexes. This will
be needed in some ENGINE code, and might serve elsewhere as well.
Note that it's implemented in such a way that the locking itself is
done through the same CRYPTO_lock function as the static locks.
WARNING: This is currently experimental and untested code (it will get
tested soon, though :-)).
