md5, sha1, sha256, sha512: support mandating use of openssl * m4/gl-openssl.m4 (gl_CRYPTO_CHECK): Adjust the --with-openssl description, to list the now 3 separate options. Also don't mention the default=no, since this is implicit given the option is described as --with-openssl rather than --without-openssl. If projects change the default they're free to document that. With --with-openssl[=yes] we now error out when the specified hash algorithm is not available in libcrypto.
