Matt Caswell e595f6cd32 Make sure we use the correct SSL object when making a callback
When processing a callback within libssl that applies to TLS the original
SSL object may have been created for TLS directly, or for QUIC. When making
the callback we must make sure that we use the correct SSL object. In the
case of QUIC we must not use the internal only SSL object.

Fixes #25788

erbsland-dev c026101be0 Correct Alert Handling for Missing Compression Methods
Fixes #7940: Updated the compression check logic to improve protocol compliance. The code now returns `SSL_AD_DECODE_ERROR` when no compression method is provided in the ClientHello message. It returns `SSL_AD_ILLEGAL_PARAMETER` if the “null” compression method (0x00) is missing.

Additionally, refactored the related test code for enhanced readability and maintainability.

Matt Caswell 7984fa683e Fix unconstrained session cache growth in TLSv1.3
In TLSv1.3 we create a new session object for each ticket that we send.
We do this by duplicating the original session. If SSL_OP_NO_TICKET is in
use then the new session will be added to the session cache. However, if
early data is not in use (and therefore anti-replay protection is being
used), then multiple threads could be resuming from the same session
simultaneously. If this happens and a problem occurs on one of the threads,
then the original session object could be marked as not_resumable. When we
duplicate the session object this not_resumable status gets copied into the
new session object. The new session object is then added to the session
cache even though it is not_resumable.

Subsequently, another bug means that the session_id_length is set to 0 for
sessions that are marked as not_resumable - even though that session is
still in the cache. Once this happens the session can never be removed from
the cache. When that object gets to be the session cache tail object the
cache never shrinks again and grows indefinitely.

Richard Levitte e077455e9e Stop raising ERR_R_MALLOC_FAILURE in most places
Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and
at least handle the file name and line number they are called from,
there's no need to report ERR_R_MALLOC_FAILURE where they are called
directly, or when SSLfatal() and RLAYERfatal() is used, the reason
`ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`.

There were a number of places where `ERR_R_MALLOC_FAILURE` was reported
even though it was a function from a different sub-system that was
called.  Those places are changed to report ERR_R_{lib}_LIB, where
{lib} is the name of that sub-system.
Some of them are tricky to get right, as we have a lot of functions
that belong in the ASN1 sub-system, and all the `sk_` calls or from
the CRYPTO sub-system.

Some extra adaptation was necessary where there were custom OPENSSL_malloc()
wrappers, and some bugs are fixed alongside these changes.
