495399ede6 Remove PackPacket's control frames parameter 
With this change it would theoretically be possible for outdated control frames to be sent, but this is quite unlikely in practice.

e43b91f633 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.

adc4ef464a simplify the CryptoSetup.SetDiversificationNonce interface 
Pass the diversification nonce via a channel instead of setting it
directly. That way there is no need to protect the diversificationNonce
member by a mutex. Also prevents a possible deadlock that occurred when
SetDiversificationNonce was called before maybeUpgradeCrypto returned.

0a6a9551f8 close the aeadChanged chan when the handshake completes 
This allows us to remove HandshakeComplete() from the CryptoSetup
interface. It also provides a signal to the session when the handshake
completes.

8c5e7818a0 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.

d1e3b541d3 replace streamFrameQueue with just-in-time framing of written data 
This commits replaces the stream frame queue with a framer which
requests data from the streams just when a frame is needed by the
packet packer. This simplifies a lot of things and allows some other
refactorings, see issue #83.

There are a few pending tests which will be fixed soon.
