6a80019862 QUIC: Remove RX depacketiser tests from QRL test suite
These create significant coupling between the QRL tests and the RXDP.
Moreover, the RXDP has no state of its own and is implemented as part of
the QUIC_CHANNEL, ergo it doesn't make that much sense to test it in
isolation.

0f7b5cc9f3 QUIC RX: Refactor unsafe DCID consistency checking
Previously, we enforced the requirement that the DCIDs be the same for
all packets in a datagram by keeping a pointer to the first RXE
generated from a datagram. This is unsafe and could lead to a UAF if the
first packet is malformed, meaning that no RXE ended up being generated
from it. Keep track of the DCID directly instead, as we should enforce
this correctly even if the first packet in a datagram is malformed (but
has an intelligible header with a DCID and length).

70d45893d0 QUIC Wire Encoding: Support Retry Integrity Tag Calculation
This adds support for calculating and verifying retry integrity tags. In
order to support this, an 'unused' field is added to the QUIC packet
header structure so we can ensure that the serialization of the header
is bit-for-bit identical to what was decoded.

203b0d00e0 QUIC RX: Do not handle auto-discard of Initial EL inside the QRX
While the QUIC RFCs state that the Initial EL should be auto-discarded
when successfully processing a packet at a higher EL, doing this inside
the QRX was not a good idea as this should be handled by the CSM.
We remove this functionality and adapt tests accordingly.

6d5d5fc9a9 QUIC RX: Support refcounted packets and eliminate wrapper
Previously, the QRX filled in a OSSL_QRX_PKT structure provided by the
caller. This necessitated the caller managing reference counting itself
using a OSSL_QRX_PKT_WRAP structure. The need for this structure has
been eliminated by adding refcounting support to the QRX itself. The QRX
now outputs a pointer to an OSSL_QRX_PKT instead of filling in a
structure provided by the caller. The OSSL_QRX_PKT_WRAP structure has
been eliminated.

948c656c66 TX key update support, RX time and PN reporting, general refactoring
- Adds an RX time field to the OSSL_QRX_PKT structure.

- Adds a timekeeping argument to ossl_demux_new which is used to determine
  packet reception time.

- Adds a decoded PN field to the OSSL_QRX_PKT structure.
  This has to be decoded by the QRX anyway, and its omission was an oversight.

- Key update support for the TX side.

- Minor refactoring.
