Prior to this commit, non-persistent pointers were being used to store sessions. When a WOLFSSL object was then freed, that freed the session it owned, and thus invalidated the pointer held in curl's cache. This commit makes it so we get a persistent (deep copied) session pointer that we then add to the cache. Accordingly, wolfssl_session_free, which was previously a no-op, now needs to actually call SSL_SESSION_free. This bug was discovered by a wolfSSL customer.
