gpg: Remove PGP-2 related cruft.
* g10/armor.c (parse_hash_header,carmor_filter): Ignore MD5 in hash header. (fake_packet): Remove pgp-2 workaround for white space stripping. * g10/filter.h (armor_filter_context_t): Remove field pgp2mode. * g10/options.h (opt): Remove field pgp2_workarounds. * g10/gpg.c (main): Do not set this field. * g10/gpgv.c (main): Ditto. * g10/mainproc.c (proc_encrypted): Use SHA-1 as fallback s2k hash algo. Using MD5 here is useless. (proc_plaintext): Remove PGP-2 related woraround (proc_tree): Remove another workaround but keep the one for PGP-5.
The removed code was either not anymore used or its use would have
caused an error message later anyway.
