Following what was done for pinch/swipe events, give hold gestures their
own distinct sequence as well. Without this it was NULL, which was already
distinct to other touchpad gestures.
This delaying of the cancel event was made to avoid intermediate cancellation
for >=2fg hold gestures followed by pinch/swipe gestures, and it worked as
long as everything was considered to have the same sequence.
Since each pinch/swipe pointer gesture now gets its own sequence, this no
longer applies, nor works. This results in zoom/rotate/swipe gestures being
stuck since the sequence for the touchpad events changes mid-gesture.
Sticking to this pattern of giving touchpad gestures their own sequence,
these hold events cannot be assumed to coalesce with other touchpad gestures,
it is better to let it propagate altogether so that both the hold gesture
and the incoming gesture trigger coherent begin and end/cancel phases.
In the worst case, this results in "::begin, ::cancel, ::begin , ..." before
triggering a touchpad gesture, but the extra begin/cancel ought to be a safe
no-op in widgets.

The textbuffer test is calling into a function defined by the AT-SPI
accessibility backend. As of commit 4ddf1b70 we only build and run the
test on Linux, but the function in question isn't really
accessibility-related: it's just a serialization function.
Let people know that they will need to use GTK with the Nahimic service
disabled or OpenGL disabled or put their GTK application into the Nahimic
backlist, or try to use GLES, since there is a known issue in the Windows
nVidia graphics drivers and Nahimic that causes GL operations to fail,
causing crashes in operations such as window resizes.
This will close issue #4113--sadly, there is nothing we can do within
GTK to fix the issue.
If gtk_builder_expose_object() is called twice with the same name, it will
result in a g_critical(). This improves that situation by checking for the
object before exposing additional times.
This turns out to be handy in situations where templates are expanded
multiple times, such as application-side implementations of UI merging.
C API users can keep dealing with the implicit equivalence of
GdkFileList and GSList, but language bindings have no idea that one type
is another, and none of them exposes GSList as a type anyway, so they
will need a way to construct a GdkFileList.
Instead of making GdkFileList mutable, and re-implement GSList, we only
provide a constructors pair that lets you create a GdkFileList from a
linked list or from an array.
The gnome-runtime-images have been recently migrated to Quay. This is already reflected in the template.

Sysprof has a new -Dagent=true build option which allows installing a
/usr/bin/sysprof-agent program (simimlar to sysprof-cli). It provides a
P2P D-Bus API to the process which can control subprocesses. It's used by
IDE tooling to have more control across container boundaries.
However, we do not need it for GTK CI.
Rubberband does not work when initiated past the last row

Clamp y at the max height of the widgets in the listview
Rubberband does not work when initiated past the last row
(warning is printed "Could not start rubberbanding: No item).
Clamp y at the max height of the widgets in the gridview
Fixes: #3462
The function gtk_grid_view_get_items_in_rect() erroneously calculates
columns less than 0 and greater than n_columns when the user attempts
to rubberband all the way to the left or right respectively. This
causes the rubberband to persistent and creates unexpected behavior.
Limit the rows to a minimum of 0 and maximum of n_columns - 1.

DnD under Windows needed 3 fixes to work with Gtk.DropTarget.
1. The droptarget_w32format_contentformat_map list never gets
filled so the gdk_win32_drop_read_async throws
"No compatible transfer format found".
This is an easy fix and done the same way in the win32 clipboard code.
2. After a drop no gdk_drop_emit_leave_event gets emitted.
This causes a second drop to trigger a bunch of assertion
'self->drop == drop' failed because the first drop is still active.
This is also an easy fix and done the same way by the macos backend.
3. Handling gdk_drop_status/gdk_drop_get_actions interaction.
In gtk_drop_target_do_drop the code
```gdk_drop_finish (self->drop, gdk_drop_get_actions (self->drop));```
calls the finish operation with the actions of the drop which triggers
```g_return_if_fail (gdk_drag_action_is_unique (action));```
in gdk_drop_finish. The code assumes that GdkDrop::actions gets
narrowed down by calling gdk_drop_status. This is hard to assure
because at the same time gdk_drop_get_actions is used by
gtk_drop_target_accept to figure out if a drag is accepted.
GdkDrop::actions serves a double purpose here as the supported source
actions and the currently agreed on action. Both the x11 and the
wayland backend get this wrong somewhat too. Under wayland/x11 when
a drag coming from a source that supports both MOVE and COPY is
first hovering a drop target that only supports COPY it is afterwards
no longer accepted by other drop targets only accepting MOVE.
Under x11 this is permanent for this drag but with wayland the drag
recovers when hovering other widgets. The win32 backend now sets the
supported source actions before any enter/move/drop and narrows them
down in gdk_win32_drop_status.
The patch only touches the win32 backend and fixes all three issues,
for me restoring DnD under windows.
Closes#4498
