make sure that at least every 20th ACK is retransmittable
...
This is important because we need to make sure that we can remove old
ACK ranges from the received packet history. The logic we implemented
before was not correct, since we only made sure that every 20th packet
would be retransmittable, but we didn't have any guarantee that this
packet would also contain an ACK frame.

introduce a queue of active streams in the streamFramer
...
The queue holds all streams that have data to send. When stream.Write or
stream.Close are called, a stream is added to this queue. It is removed
from the queue when all available (at that moment) data was sent.
This way, we don't need the round robin scheduling (which, for every
packet sent, asked every single open stream if it had data) any more.

This callback also takes the stream ID, which will later be used to
create a queue of streams that have data for writing available.

when forcing a retransmittable packet, bundle the PING with other frames
...
We're sending a retransmittable packet every 20 packets (if there are no
other frames to send). To make a packet retransmittable, we add a PING
frame. We should bundle this PING with an ACK.

No functional change expected.
The error was only non-nil if some required values for the STOP_WAITING
frame were not set. It should be sufficient to throw an error when
attempting to write an invalid STOP_WAITING frame.

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.
