only accept 3 retries
...
While the server is allowed to perform multiple Retries, the client
should impose a limit in order to avoid being caught in an endless loop.

always use connection IDs longer than 8 bytes when sending a Retry
...
A server is allowed to perform multiple Retries. There's little to gain
from doing so, but it's something our API allows. If a server performs
multiple Retries, it must use a connection ID that's at least 8 bytes
long. Only if it doesn't perform any further Retries it is allowed to
use shorter IDs. Therefore, we're on the safe side by always using a
long connection ID.
This shouldn't have a performance impact, since the server changes the
connection ID to a short value with the first Handshake packet it sends.

use a random length destination connection ID on the Initial packet
...
The destination connection ID on the Initial packet must be at least 8
bytes long. By using all valid values, we make sure that the everything
works correctly. The server chooses a new connection ID with the Retry
or Handshake packet it sends, so the overhead of this is negligible.

use callbacks for signaling the session status
...
Instead of exposing a session.handshakeStatus() <-chan error, it's
easier to pass a callback to the session which is called when the
handshake is done.
The removeConnectionID callback is in preparation for IETF QUIC, where a
connection can have multiple connection IDs over its lifetime.
