e94db952b7 correctly handle key updates within the 3 PTO period 
We need to:
* stop the timer to drop the previous generation
* correctly log that the N-1 keys are dropped immediately when keys are
updated to N+1

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.
