gpg: Document use of node flags in import.c and remove unused args.
* g10/import.c (NODE_GOOD_SELFSIG): New. Use instead of 1. (NODE_BAD_SELFSIG): New. Use instead of 2. (NODE_DELETION_MARK): New. Use instead of 4. (NODE_FLAG_A): New. Use to mark new nodes in merge_blocks. (chk_self_sigs): Remove unused args FNAME and PK. (import_one): Adjust call. Simplify error return because chk_self_sigs does not return an error code. (append_uid, append_key, merge_sigs, merge_keysigs): Remove unsued args FNAME and KEYID. (merge_blocks, import_one, import_secret_one) (import_revoke_cert): Remove unused arg FNAME.
