gpgv: New option --print-notation.

* g10/keylist.c (print_matching_notations): New.
* g10/mainproc.c (check_sig_and_print): Call this.
* g10/options.h (opt): Add field print_notations.
* g10/gpgv.c (oPrintNotation): New.
(opts): Add "print-notation".
(main): Implement.

I had the code floating around but can't remember what triggered me to
write this.  But it might eventually be useful, so better apply it.
