We recently removed reference counting for EVP objects, but kept the refcounting when we build with no-cached-fetch. There is a corner case in which providers in builds that do caching may still request non-caching by setting *no_cache = 1 in their query operations. OQS tripped over this here: https://github.com/open-quantum-safe/oqs-provider/pull/787 When a provider requests no caching, we need to treat those algorithms as though we are running in a no-cached-fetch build and still do ref counting on them. Teach our algorithms implementation to understand when a provider is requesting non-caching, mark them as such and ref count only those.
