This mostly entails passing around a provider pointer, and handling queries that includes a pointer to a provider, where NULL means "any". This also means that there's a need to pass the provider pointer, not just down to the cache functions, but also be able to get it from ossl_method_store_fetch(). To this end, that function's OSSL_PROVIDER pointer argument is modified to be a pointer reference, so the function can answer back what provider the method comes from. Test added. Fixes #16614 Reviewed-by: Tomas Mraz <tomas@openssl.org> Reviewed-by: Matt Caswell <matt@openssl.org> (Merged from https://github.com/openssl/openssl/pull/16725)
