Now direct tracker connection for transporting retrieved
parts of data is used, instead of D-Bus. This should result better
performance for PBAP requests.
Each part of results is now fetched from tracker asynchronously
and getting more results can be stopped in any moment -
GCancellable stored in phonebook_data is used for that purpose.
If processing of data has finished (or it was cancelled) then cleanup
of pending_reply is done in last invocation of
async_query_cursor_next_cb.
