LibreSSL 3.5.0 fails to compile with these shims. We could have just removed the LibreSSL check from the pre-processor condition, but it seems that these shims are no longer needed because all the supported versions of OpenSSL and LibreSSL have those functions. According to EVP_ENCRYPTINIT(3) manual page in LibreSSL, EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() first appeared in OpenSSL 0.9.8b, and have been available since OpenBSD 4.5.
