66fd3b5195 expose the ConnectionState in the Session 
The ConnectionState contains basic details about the QUIC connection.

a20e94ee16 use separate streamsMaps for gQUIC and IETF QUIC 
This is a lot of duplicate code for now, but it will make moving towards
the new stream ID mapping in IETF QUIC (and unidirectional streams) much
easier.

b687dd774f remove the Range method in the streamsMap 
streamsMap.Range was only used to pass the stream flow control window to
all open streams after receiving the peer's transport parameters. It's
easier to pass the transport parameters to the streamsMap directly.

8a3f807a12 immediately delete a stream when it is completed 
By introducing a callback to the stream, which the stream calls as soon
as it is completed, we can get rid of checking every single open stream
if it is completed.

99a2853e7d remove non forward-secure dialing 
This was broken for a long time, and won't be available when using the
TLS 1.3 handshake.

d9c107b034 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.

a5d3eaea61 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.

c270de3538 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.

d2e31c04ab generate the streamI mock in the quic package 
By doing so, we can mock private methods of the stream, so they cannot
be type-asserted by users of quic-go.

8e1f62f749 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.

ad22ed9d16 disable connection migration 
Connection migration is complicated: We need to verify the new path, and
reset the congestion controller. In the IETF draft, connection migration
is still work in progress.

1f644debd4 set if a stream contributes to connection flow control 
This depends on the version. In gQUIC, stream 1 and 3 don't contribute,
in IETF QUIC only stream 0 doesn't contribute.

a1a4f35096 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.
