By passing the events during a (midal-ish) drag operation to the main loop,
we're able to keep up with what's happening. This allows the internal
drag state (GtkDragSource) to be updated and be done when the drag is
done.
The Drag data should pass through the macos pasteboard system.
We need to provide some pasteboard type. Let's make it a "URL",
which is a pretty generic type anyway.
The handling is done similar to drag targets.
Note that dragging is a modal action on macos: no events
are sent to the main window. This could cause trouble when
we finish the drag, and not finish the gesture in GTK.
This will make it easier to reuse from drag integration so that we don't
require clipboards for everything.
We will need to subclass the pasteboard provider twice, however, both
for clipboard and dragging.
When transitioning from internal to malloc, the strings were placed in
the wrong order to g_strconcat(). This fixes an issue with undo where
if you hit the boundary in just the right way, your undo stack will do
unexpected things.
Fixes#5506
When the model button just has a text label and accel text,
the button fills and the accel label is implicitly aigned to end.
When there's also a icon, even though it's not shown (because
icons are only shown if there's no text), the button doesn't fill
and the accel ends up not aligned (assuming one of the other buttons
is longer). Ensure that the accel label is aligned to the end.

Use the fallback logic to generate the base path for the GtkAtSpiRoot
if the GApplication has no DBus object path to guarantee that
the base path will not stay NULL.
`gtk_at_spi_cache_add_context()` checks if the GtkAtSpiContext's path
is NULL before inserting the context object into the hash table.
Do the same in `gtk_at_spi_cache_remove_context()` to avoid a NULL
pointer dereference in `g_str_hash()` during the hash table lookup
if a context with NULL path is removed. That can happen when the
GtkAtSpiRoot::base_path is NULL, which, in turn, can happen if
`g_application_get_dbus_object_path()` returns NULL.
