This patch adds two new flags to the callback function -- did_connect and did_timeout -- that are calculated inside of web.c using information from libcurl. This allows the announcer to detect timeouts more accurately and also to distinguish between unresponsive peers (which get the preexisting "Tracker did not respond" error message) and unconnectable peers (which get a new error message, "Could not connect to tracker").
make sure to call gtk_list_store_set() on rows matching torrents whose tr_stat.recheckProgress value has changed, triggering a row change event that causes the verify progress change to be displayed.
Clearing the model on shutdown generated a warning because it used the wrong cast. Rather than fixing the cast, add tr_core_clear() for symmetry with tr_core_load().
Long description in #3970. Split tr_core's torrent GtkTreeModel into two models: one low-level unsorted one, and one proxy sorted one. That way we don't have to disable sorting before walking through the low-level one to sync the table's attributes with the tr_torrent and tr_stat.
The main window called gtk_tree_model_filter_refilter() once per second to refresh the torrent list's filtering. This is not an efficient approach: gtk_tree_model_filter_refilter() emits a "row changed" event for every row, causing unnecessary re-rendering.
I've removed the call to gtk_tree_model_filter_refilter() and expanded the model to includes all the fields necessary for filtering. That way we only fire "row changed" events for rows that actually change.
By reducing the number of renders in steady state, this might ameliorate https://bugs.launchpad.net/ubuntu/+source/transmission/+bug/655024
However it will *not* help the related "CPU spikes to 100% on scrolling" ticket at https://trac.transmissionbt.com/ticket/3887 because rendering paused torrents is still exceptionally expensive in the murrine theme.
The Berne Convention says that the copyright year is moot, so instead of adding another year to each file as in previous years, I've removed the year altogether from the source code comments in libtransmission, gtk, qt, utils, daemon, and cli.
Juliusz's copyright notice in tr-dht and Johannes' copyright notice in tr-lpd have been left alone; it didn't seem appropriate to modify them.
1. remove tr_sessionGetActiveTorrentCount()
2. make tr_sessionCountTorrents() package-visible instead of public.
3. make tr_torrentGetActivity() private instead of public.
