QSslSocket (OpenSSL) improve alert messages handling
1. Add a new verification callback. This gives an option to report errors directly from this callback (by emitting handshakeInterruptedOnError()). This allows an application to explain to its peer why the handshake was interrupted (by sending a corresponding alert message). 2. This also means we want to notice such alerts (in Qt, from the application's point of view, they are mostly informational only, no interaction is required). So we also introduce a new 'info callback', that can notice alert messages read or written. We also introduce two new enums describing the level and type of an alert message. QSslSocket gets three new signals (for incoming/outgoing alerts and verification errors found early). 3. In case we requested a certificate, but the peer provided none, we would previously abruptly close the connection without a proper alert message (and such a situation is not handled by any verification callbacks, since there is no certificate(s) to verify essentially). So we now introduce a new verification option that maps to what OpenSSL calls 'SSL_VERIFY_FAIL_IF_NO_PEER_CERT'. This way, the proper alert will be generated.
