* Add compat operator* for RefPtr
* Rename `*_tree_view_*` button handling helpers to `*_item_view_*`
* Move torrent item colors to CSS
* Switch to list view for torrents list (GTK 4)
* Bump Fedora image to 39 (current rawhide) for GTK 4.11
Enable deprecations as there're lots of them in 4.11 and I'm not keen on
fixing them all right now. Disable warnings as errors due to
-Warray-bounds issue somewhere in libfmt.
* Automatically (re)order include directives (GTK client)
Include our headers first to ease IWYU enforcement.
* Fix includes missing from headers (GTK client)
* Fix build on Mac after includes reordering
* Use `Gio::List{Model,Store}` for torrents
Switch from `Gtk::{TreeModel,ListStore}` in preparation for cell
renderers deprecation in GTK 4.10. That will require switching to the
new view classes (`Gtk::{Column,List}View`) which only work with `Gio`
models. Implement an adapter to support GTK+ 3 where the old view class
(`Gtk::TreeView`) only works with `Gtk` models; it is effective enough
but requires a signal connection per item to notify on row changes.
Refactor filtering and sorting (which now happen over the new model) to
use compatible `Gtk::Filter` and `Gtk::Sorter` classes. Although these
classes are only present in GTK 4, the abstraction is suitable for GTK+
3 as well so make our subclasses work for both versions.
Since items (of `Torrent` class) of the new model provide only a very
limited (by design) layer of compatibility with GTK+ 3 way of doing
things, refactor selection handling to do it the new way. Move selection
helpers into `MainWindow` to abstract them away since new view classes
handle it differently.
* Improve session load performance based on profiling results
