c9bfde9ac0 fix handling of multiple handshake messages in the case of errors 
When receiving a handshake message after another handshake messages that
doesn't cause any action from the TLS stack (i.e. Certificate and
CertificateVerify), the handshake would run into a deadlock if the first
of these handshake messages caused an error in the TLS stack.

We need to make sure that we wait until a message has been fully
processed before proceeding with the handshake.

The RTTStats are used by the logging package. In order to instrument the
congestion package, the RTTStats can't be part of that package any more
(to avoid an import loop).
