SSL: register OpenSSL threading callbacks when we can't access Qt's OpenSSL.

We neglected to register our own callbacks for locking and thread IDs
when we removed the restriction that we only allow one copy of OpenSSL
in the address space. (f544524d4c3289bf3341d685277de0e6a6895469)

This commit remedies that by providing our own set of callbacks for
locking and getting thread IDs to OpenSSL.

Previously, we just expected that Qt would properly initialize OpenSSL.
However, when Qt and us use separate copies of OpenSSL -- we have to do
it ourselves.
