allowing it in recent mode cited in the comment just above the

Closes#2178
Replace the gdk_surface_move_to_rect() API with a new GdkSurface
method called gdk_surface_present_popup() taking a new GdkPopupLayout
object describing how they should be laid out on screen.
The layout properties provided are the same as the ones used with
gdk_surface_move_to_rect(), except they are now set up using
GdkPopupLayout.
Calling gdk_surface_present_popup() will either show the popup at the
position described using the popup layout object and a new unconstrained
size, or reposition it accordingly.
In some situations, such as when a popup is set to autohide, presenting
may immediately fail, in case the grab was not granted by the display
server.
After a successful present, the result of the layout can be queried
using the following methods:
* gdk_surface_get_position() - to get the position relative to its
parent
* gdk_surface_get_width() - to get the current width
* gdk_surface_get_height() - to get the current height
* gdk_surface_get_rect_anchor() - to get the anchor point on the anchor
rectangle the popup was effectively positioned against given
constraints defined by the environment and the layout rules provided
via GdkPopupLayout.
* gdk_surface_get_surface_anchor() - the same as the one above but for
the surface anchor.
A new signal replaces the old "moved-to-rect" one -
"popup-layout-changed". However, it is only intended to be emitted when
the layout changes implicitly by the windowing system, for example if
the monitor resolution changed, or the parent window moved.
Changing the autohide property means the popover needs to be remapped.
Remapping may need user interaction, so lets just unrealize the popover
if the property changes, forcing the application to remap it should it
be shown again.
Add properties, and use string arrays instead of lists.
Among other things, this renames gtk_icon_theme_list_icons
to gtk_icon_theme_get_icon_names.

By running it in the capture phase, it will not be starved for events by
the button's click source and make drags actually start a color drag
operation.
Actually use GValues for the DND operation instead of sending GBytes of
pointer addresses through pipes.
This is a bit complicated because we need to special-case rootwindow
drops, because they're handled on the source side, so we need a custom
ContentProvider.
Enter the Emoji inseration in the undo history.
Also, stop stashing away the selection when we
pop up the Emoji chooser, and use the selection
as-is when we insert the Emoji.
The old code did mimetype checks everywhere when type compatibility has
since been moved to the GtkDropTarget::accept signal.
So the code can now just assume a compatible mime type exists.
Content providers are meant to be immutable, apart from very special
cases, but in those cases they need to emit
gdk_content_provider_content_changed().
Having a constructor that just uses a get_func invites abuse of this
by not making developers aware of those requirments.
In fact, all users in GTK failed to do this.
Instead, code should use the GtkDragSource::prepare signal to create
content providers when needed.
The same problem exists with gdk_content_provider_new_with_formats(),
but this commit doesn't touch that.
In Vala and JS at least, gtk_widget_get_css_name() and
gtk_widget_class_get_css_name() are resolved to
GtkWidget.get_css_name().
To avoid this problem, we rename the class version.
Accessors like these are weird to have and we can add widgets to the
content area via gtk_container_add() as well as add widgets to the
action area via gtk_info_bar_add_action_widget().
