Add "origin" field to EVP_CIPHER, EVP_MD
Add a "where did this EVP_{CIPHER,MD} come from" flag: global, via fetch, or via EVP_{CIPHER,MD}_meth_new. Update EVP_{CIPHER,MD}_free to handle all three origins. The flag is deliberately right before some function pointers, so that compile-time failures (int/pointer) will occur, as opposed to taking a bit in the existing "flags" field. The "global variable" flag is non-zero, so the default case of using OPENSSL_zalloc (for provider ciphers), will do the right thing. Ref-counting is a no-op for Make up_ref no-op for global MD and CIPHER objects Deprecate EVP_MD_CTX_md(). Added EVP_MD_CTX_get0_md() (same semantics as the deprecated function) and EVP_MD_CTX_get1_md(). Likewise, deprecate EVP_CIPHER_CTX_cipher() in favor of EVP_CIPHER_CTX_get0_cipher(), and add EVP_CIPHER_CTX_get1_CIPHER(). Refactor EVP_MD_free() and EVP_MD_meth_free() to call new common evp_md_free_int() function. Refactor EVP_CIPHER_free() and EVP_CIPHER_meth_free() to call new common evp_cipher_free_int() function. Also change some flags tests to explicit test == or != zero. E.g., if (flags & x) --> if ((flags & x) != 0) if (!(flags & x)) --> if ((flags & x) == 0) Only done for those lines where "get0_cipher" calls were made.
