Inline the pre-13273237a65d46186b6bea0b51aec90670d4598a versions of EVP_CIPHER_CTX_iv(), EVP_CIPHER_CTX_original_iv(), and EVP_CIPHER_CTX_iv_noconst() in evp.h. These macros are internal-only, used to implement legacy libcrypto EVP ciphers, with no real provider involvement. Accordingly, just use the EVP_CIPHER_CTX storage directly and don't try to reach into a provider-side context. This does necessitate including evp_local.h in several more files.
