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.

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

queue stream window updates directly from stream.Read
...
By queueing receive window updates directly from stream.Read, it is no
longer necessary to ask every stream for window updates when sending a
packet.

By doing so, we can mock private methods of the stream, so they cannot
be type-asserted by users of quic-go.

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.

Connection migration is complicated: We need to verify the new path, and

send initial version in the CHLO, not the current version
...
This commit fixes two bugs:
1. In the CHLO, we need to send the initial QUIC version. It will differ
from the current version if version negotiation was performed.
2. The session setup was using the wrong version (current version, and
not the initial version), such that we would have sent the wrong version
in the TLS handshake as well.
