This issue was discoevered while I was testing SSL_new_from_listener()
using a newly created unit test. It has turned out the QUIC stack
at few places contain pattern as follows:
foo(QUIC_WHATEVER *q, BIO_ADDR *a)
{
q->a = *a;
}
The problem is that derefencning a that way is risky. If the address `a`
comes from BIO_lookup_ex() it may actually be shorter than sizeof(BIO_ADDR).
Using BIO_ADDR_copy() is the right thing to do here.

It was noticed recently that the enum for QUIC encryption levels doesn't
match the ordering that is outlined in the RFC. RFC 9000 s. 12.2 and
RFC 9002 s 14.4.1 indicate that encryption level ordering is
INITIAL/0RTT/HANDSHAKE/1RTT, but our enum is in the order
INITAL/HANDSHAKE/0RTT/1RTT.
Our enum isn't a direct wire translation, so as long as the wire->enum
mapping done in ossl_quic_pkt_type_to_enc_level is done consistently it
ideally wouldn't matter, but because we do coalescing in
ossl_quic_tx_packetiser_generate by iterating through all the values in
the enum, its possible we may coalesce in the wrong order when we do
start implementing 0RTT support.
Fix it by adjusting the enum properly to match the RFC order. This also
necessitates and adjustment to the archetypes array, which is a two
dimensional array indexed by encryption level and frame archetype
(PROBE/NORMAL/ACK ONLY). Moving the 0RTT enc level to index 1 requires
moving the (formerly) index 2 0RTT array row to be at index 1.

If a single packet contains data from multiple streams we need to keep track
of the cummulative connection level credit consumed across all of the

txp_generate_stream_frames() plans chunks of data to send via the
function txp_plan_stream_chunk(). That function may clamp the amount in
the chunk due to flow control, even though there is more available to send.
We should take this into account when deciding whether or not to try
serializing the next chunk.
