Werner Koch 67a58118ab
gpg: Prepare to pass additional context to the list functions. 
* g10/keylist.c (struct sig_stats): Rename to keylist_context and add
field check_sigs.
(keylist_context_release): New.
(list_all): Set listctx.check_sigs and call release func.
(list_one): Ditto.
(locate_one): Ditto.
(list_keyblock_print): Use .check_sigs field.  Repalce arg opaque by
listctx.
(list_keyblock): Ditto.  Make static.
(list_keyblock_direct): New.
* g10/keygen.c (do_generate_keypair): Replace list_keyblock by
list_keyblock_direct.
--

This is in preparation for the server mode and for a patch to speed up
--list-sigs.
