17d9860db6 declare the handshake confirmed when receiving an ACK for a 1-RTT packet 
... on the client side. Both the receipt of HANDSHAKE_DONE and the
receipt of an ACK for a 1-RTT packet are sufficient for declaring
confirmation of the handshake.

91629cd979 only start PMTUD after handshake confirmation 
Our PMTUD packets are never coalesced packets. Since we try packing
coalesced packets until the handshake is confirmed, it makes sense to start
PMTUD then.

162cb16b31 cache the serialized OOB in the conn, not in the packet info 
We're allocating a lot of packetInfo structs during the lifetime of a
connection. It's better to keep that struct as small as possible.

eb6bdfdfc1 Use the correct source IP when binding multiple IPs 
When the server is listening on multiple interfaces or interfaces with
multiple IPs, the outgoing datagrams are sometime delivered with the
wrong source IP address.

In order to fix that, each quic connection needs to extract the
destination IP (and optionally interface id) of the received datagrams,
and set it as source IP (and interface) on the sent datagrams.

On most platforms, this can be done using ancillary data with recvmsg()
and sendmsg(). Some of the machinery for this is already there for ECN,
this change extends it to read the destination IP info and write it to
the outgoing packets.

Fix #1736

1-RTT packets.

53270dde9e only read multiple packets at a time after handshake completion 
It's more important that acknowledge packets in a timely manner before
handshake completion. On the server side, we should send out the HANDSHAKE_DONE
frame as soon as possible.

2c2b758dee allow sending of ACKs when pacing limited 
An endpoint that is only receiving data won't have an accurate estimate
of the congestion window, and therefore derive a very low pacing
frequency.
In this situation it still needs to be able to send frequent ACKs to the
peer in order to allow full utilization of the bandwidth. We therefore
need to allow ACKs even when pacing-limited.
