Move private function out of the AT-SPI a11y backend
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.

running.md: Mention about issue with Nahimic on Windows
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.
gtkbuilder: check for existing object before extending template
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.
build: configure subproject sysprof with -Dagent=false
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.

gridview: Limit rectangle to gridview columns
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.
mountoperation: Free user_widgets list upon dialog destruction
There's a list user_widgets that contains all of the entries and
selections during authentication. This is only freed upon
finalizing the GtkMountOperation. It's possible (and true for the
GVFS SMB implementation) that a MountOperation can have the
gtk_mount_operation_ask_password_do_gtk () function called multiple
times (i.e. bad password). The user_widgets list grows with now
invalid pointers to old widgets (causing unexpected behavior and
seg faults).
Free the user_widgets list upon dialog destruction, we don't need it
anymore.
mountoperation: Select "Anonymous" check button by default
It is already explicitly assumed that anonymous authentication will
be used when available, but it is not clear to the user since neither
of the check buttons are selected. Select the Anonymous check button
by default.
When computing a transform value, there is nothing
to do, but we still need to copy the matrix from
src to dest, since it depends on the other transforms
in the array whether we are using the src or the
dest in the end.
This fixes cases like
-gtk-icon-transform: perspective(100px) matrix(1,2,...);
which would otherwise end up with a zero matrix.

gdk/wayland: Use last implicit grab serial for DnD start requests
This serial should be that from a button press/touch down/etc, use
the last implicit grab here, which will presumably be from the same
device that triggered the event.

tree/iconview: Use a unique drag action in drag_enter/motion callbacks
Functions already exist for providing a unique drag action for gdk_drop_finish().
Reuse these functions in the drag_enter/motion callbacks, since they require
a unique action as the return value.
The XDND suggested action is a relic from when the source would control
the action for a drop. With the new GtkDropTarget the target decides
the action (not the source). That means the all of the returned
results from the ::enter and ::motion handlers will be unexpectely
ignored. Prefer to use the preferred action over the x11 suggested action.
gdk_x11_drop_update_actions() sets actions to
drop_x11->suggested_action when !drop_x11->xdnd_have_actions
and then sets it again to drop_x11->suggested_action if it is.
If xdnd_have_actions is true use xdnd_actions.

popover: Correctly substract arrow height when measuring popover widget
For default popover arrow position and default height-for-width layout mode,
natural_width is calculated first with for_size=-1 and orientation=HORIZONTAL,
at the end of gtk_popover_measure() natural_width won't be added with tail_height.
Then to measure with for_size=natural_width and orientation=VERTICAL, obviously
for_size shouldn't be substract with tail_height.
The wrong logic will force content in popover gets less width and then text labels
in popover may get wrapped unnecessarily.
