keyboxd: Implement multiple search descriptions.
* kbx/kbx-client-util.c (kbx_client_data_simple): New. * kbx/backend-sqlite.c (struct be_sqlite_local_s): Add field descidx. (be_sqlite_search): Use that. * g10/call-keyboxd.c (keydb_search): Implement multi mode.
With that change the keyboxd is at par with the keybox code.
