gpg: Extend the "sig" record in --list-mode.

Browse source 
* g10/getkey.c (get_user_id_string): Add arg R_NOUID.  Change call
callers.
(get_user_id): Add arg R_NOUID.  Change call callers.
* g10/mainproc.c (issuer_fpr_string): Make global.
* g10/keylist.c (list_keyblock_colon): Print a '?' for a missing key
also in --list-mode.  Print the "issuer fpr" field also if there is an
issuer fingerprint subpacket.
--

Scripts used to rely on the "User ID not found" string even in the
--with-colons listing.  However, that is not a good idea because that
string is subject to translations etc.  Now we have an explicit way of
telling that a key is missing.  For example:

  gpg --list-sigs --with-colons | \
    awk -F: '$1=="sig" && $2=="?" {if($13){print $13}else{print $5}}'

Prints all keyids or fingerprint of signing keys for which we do not
have the key in our local keyring.
