* Switch the order rak::advance_bidirectional iterates.

* When testing for mincore, cast the address pointer to (char*).

* Failure during syncing causes the download to stop, unless
flag_ignore_error is set.

* Trigger storage error signal for HashTorrent in
DownloadWrapper::receive_initial_hash.
