* Removed core::HashQueue, using the "hashing" view and a function in

core::Manager instead.

* Added a new :rtorrent:hashing state so we can distinguish between
initial hashing and manual rehashes. The former is cleared if the
download is paused.

* Added a hash failed flag to core::Download. This is used to skip
entries in the hashing view that either failed to open or are in the
process of being erased from DownloadList.

* torrent::Bitfield::unset was incrementing, rather than decrementing,
the m_set counter.

* Replaced all torrent::internal_error's in rtorrent with
torrent::client_error.

* ^D now checks :rtorrent:state to decide whetever to stop or erase a
download. Downloads queued for hashing will now stop rather than be
deleted.
