+ af_alg: port to Ubuntu 22.04
+ Without this patch, maintainer builds of coreutils fail on Ubuntu
+ 22.04 with diagnostics like "./lib/gl_openssl.h:79:1: error:
+ 'MD5_Init' is deprecated: Since OpenSSL 3.0
+ [-Werror=deprecated-declarations]". From
+ <https://wiki.openssl.org/index.php/OpenSSL_1.1.0_Changes>
+ it appears that Gnulib needs to either define OPENSSL_API_COMPAT
+ to a version less than 3.0, or use a compatibility layer, or
+ assume OpenSSL 1.1.0 or later. The simplest workaround is to
+ define OPENSSL_API_COMPAT for 1.1.1, the oldest OpenSSL release
+ still supported. A better fix would be to rewrite the code to
+ assume OpenSSL 1.1.1 or later, and stop using the older API.
+ * lib/md5.h, lib/sha1.h, lib/sha256.h, lib/sha512.h, lib/sm3.h:
+ Define OPENSSL_API_COMPAT to 0x10101000L to suppress
+ the deprecation warnings on Ubuntu 22.04.
