use separate packet number spaces for sending packets
...
Packet numbers now start at 0 for every packet number spaces.
Furthermore, an ACK frame now only acknowledges packets in the packet
number space it was sent in.

don't close the session when unpacking a packet fails
...
Before a packet is successfully authenticated, we can't be sure if this
is a packet that was injected by an attacker. If any error occurs before
authenticating the packet, we should just drop it.

This way, we can handle every parsed frame directly, and avoid
allocating a slice of parsed frames.

This introduces a reference counter in the packet buffer, which will be

This variable was only used to pass the packet number an ACK was

passing the value to handleAckFrame() directly.

immediately remove sessions that were closed remotely
...
We only need to keep sessions that were closed locally, in order to
retransmit the CONNECTION_CLOSE packet. For sessions that were closed by
the peer, we don't need to wait for any more packets, and there's also
no CONNECTION_CLOSE to retransmit. The same applies for sessions that
were destroyed when receiving a Version Negotiation or a Retry packet.
