never use a 6 byte packet number
...
According to the IETF draft, the only packet number lengths are 1, 2 and
4 bytes. With the given formula for the packet number derivation, we
would have only sent a 6 byte packet number if the difference between
the largest unacked and the current packet number exceeded 2^31, so this
would never have happened anyway.

Fix encryption of stream data
...
This commit splits up handling of the crypto stream and the other streams in the framer, crypto setup, and the packer.
- Crypto stream data is handled separately and should never be sent unencrypted or FW-secure. Fixes #544 .
- Non-crypto stream data is only sent with FW encryption on the server and only with non-FW or FW encryption on the client. Fixes #611 .
The crypto stream is current excluded from flow control (#657 ), but that shouldn't be an issue in practice for now.

retransmit the diversification nonce in the packet carrying the SHLO
...
The packet containing the SHLO is the only packet that is sent with
initial encryption. If it is lost, we need to make sure that the
diversification nonce is included in the PublicHeader, otherwise the
client will not be able to derive the keys for the forward-secure
encryption.
