In hash.h, we use these platform_ variables to set up the function pointers for, e.g., the_hash_algo->init_fn(), etc. But while these header files have a header-specific macro that prevents them declaring their structs / functions multiple times, they unconditionally define the platform variables, making it impossible to load multiple SHA-1 implementations at once. As a prerequisite for loading a separate SHA-1 implementation for non-cryptographic uses, only define the platform_ variables if they have not already been defined.

Use the newer EVP_* API with OpenSSL 3+ (only) despite being more error-prone and less efficient due to heap allocations.
