* acinclude.m4 (GNUPG_GPG_DISABLE_ALGO): New. * configure.ac: Add --enable-gpg-* options to disable non MUS algorithms. * g10/misc.c (map_cipher_openpgp_to_gcry): Implement these options. (openpgp_pk_test_algo2): Ditto. (map_md_openpgp_to_gcry): Ditto. (openpgp_cipher_test_algo, openpgp_md_test_algo): Simplify. -- We have a similar feature in GnuPG-1. Although we don't shrink the size of the gpg binary by disabling algorithms (they are implemented in Libgcrypt), this feature may still be useful for inerop testing.
