  THREADING: Make CRYPTO_MUTEX and CRYPTO_CONDVAR typesafe

There was really no need for this to be void and it made bugs very easy
to introduce accidentally, especially given that the free functions
needed to be passed a pointer to the pointer.

Also fix some bugs in the QUIC code detected immediately by this change.
