gpg: Prepare for signatures with ISSUER_FPR but without ISSUER.

* g10/getkey.c (get_pubkey_for_sig): New.
(get_pubkeyblock_for_sig): New.
* g10/mainproc.c (issuer_fpr_raw): Give global scope.
(check_sig_and_print): Use get_pubkeyblock_for_sig.
* g10/pkclist.c (check_signatures_trust): Use get_pubkey_for_sig.
* g10/sig-check.c (check_signature2): Ditto.
(check_signature_over_key_or_uid): Ditto.

GnuPG-bug-id: 4046

The whole getkey stuff is still a mess with way to much duplication
and missing caching of already fetched data.
