Add ci test to run against minimal gcc version we support

We currently support gcc 9 as a minimum compiler version.  We should run
at least one ci job against that minimal version to make sure we don't
break anything.

Most notably this will help us catch errors if we attempt to use
intrinsics that aren't supported by that compiler.

Harden digest context deserialization

The deserialization functions for SHA2 and SHA3 digest contexts did not
sufficiently validate the incoming data. Corruption in transmission or
on saved disk data could cause a out-of-bounds memory access if buffer
sizes did not match expected values.

Add sanity checks to the SHA2 and SHA3 deserialization functions to validate
buffer-related fields before they are used. The serialization format for these
digests has been changed to place these critical fields early in the stream to
enable this validation.

Additionally, add a note to the EVP_DigestInit man page to warn users that
deserialization should only be performed on trusted data. The checks we
implement are not meant to address processing of untrusted data
maliciously crafted by an attacker.

Application that need to store data or transmit it through untrusted
media SHOULD implement proper encryption and message authentication
on their own using things like CMS or other appropriate secure message
containers.

These check have been added also to quiet a bit security researchers
that try to find any way to claim CVE bounties even in completely
unlikely or invalid scenarios.

method store performance improvements

The proposed architectural change focuses on improving concurrency and
reducing contention within the method store. The fundamental concept
involves moving away from a monolithic synchronisation
mechanism—specifically, a single read-write lock (rwlock)—that
currently guards the entire method store.

Instead of this single point of contention, the strategy is to
introduce per-shard synchronisation. This means the method store will
be partitioned, or sharded, into several independent segments. Each of
these segments, or shards, will be protected by its own dedicated
read-write lock.

The data in the table below was generated by running evp_fetch twenty times per thread.

Prevent freeing of parent listener in SSL_listen_ex

Its been reported that, when using SSL_listen_ex to obtain a new
connection from a listener, that, if the listener is freed prior to the
obtained connection, we get use-after-free conditions when freeing said
obtained connections.

This occurs because SSL_listen_ex fails to take a reference on the
parent listener SSL object (in the same way that SSL_new_from_listener
does).  If the listener is freed first, then several listener resources
are freed, which the obtained connection still makes use of, hence the
use-after-free.

The fix is to do what SSL_new_from_listener does, namely:
1) Increase the reference count on the listener SSL object.
2) Ensure that the connection qc->listener points to the listener object
   so that, when the connection is freed, we call SSL_free on the
   listener object, dropping the reference count we take in
   SSL_listen_ex.

While we're at it, this PR also modifies the quicapi test for testing
the SSL_listen_ex call, freeing the listener first to ensure that the
increased refcount holds the SSL object data stable until the connection
is freed.

Thanks to Stanislav Fort at Asile Research for pointing out this issue.

Use generated param decoders in SHA provider

Refactor the SHA provider's context parameter handling in sha2_prov.c to use
the generated parameter decoder framework.

This change replaces manual parameter lookups using `OSSL_PARAM_locate` and
static `OSSL_PARAM` arrays with generated decoder functions and structs. A new
template, `sha2_prov.inc.in`, is added to create the necessary decoders during
the build.

This simplifies the code, reduces boilerplate, and improves type safety.

Add EVP_MD_CTX serialization for SHA3/SHAKE

Implement context serialization and deserialization for the SHA3, KECCAK,
SHAKE, and KMAC provider-based digests.

This is achieved by handling the `OSSL_DIGEST_SERIALIZATION` parameter in
get_ctx_params and set_ctx_params. A custom format is used to store the KECCAK
state, including a magic number and an algorithm identifier to ensure the
context is not loaded into an incompatible digest instance.

This allows an EVP_MD_CTX to be saved and restored, which is useful for
applications that need to checkpoint hashing operations. The existing EVP
serialization tests have been extended to cover these new algorithms.

Add serialization for SHA-2 digest contexts

This commit introduces the ability to serialize and deserialize the internal
state of SHA-2 digest contexts (SHA-256 and SHA-512 families).

This functionality is exposed via the new OSSL_DIGEST_SERIALIZATION parameter,
which can be used with EVP_MD_CTX_get_params() to retrieve the state and with
EVP_DigestInit_ex2() to restore it into a new context.

This allows an application to save the state of a hash operation and resume it
later, which is useful for process migration or for saving the state of long-
unning computations. A new test case has been added to verify this.

Add EVP digest context serialization

This commit introduces two new functions, EVP_MD_CTX_serialize and
EVP_MD_CTX_deserialize, to the EVP digest API.

These functions allow an application to save the state of a digest
context (EVP_MD_CTX) and restore it later. This is useful for
checkpointing long-running computations, enabling them to be paused
and resumed without starting over.

The implementation adds the OSSL_FUNC_DIGEST_SERIALIZE and
OSSL_FUNC_DIGEST_DESERIALIZE dispatch functions for providers to
supply this functionality.
