gtk_show_uri_on_window() will pass enough information for Portal helpers
to allow dialogue parenting in Flatpak, gtk_show_uri() won't, so
deprecate it.

Update the autotools scripts to support Visual Studio 2017 builds by
copying the Visual Studio 2013 projects and updateing the items as
necessary to obtain the Visual Studio 2017 projects.
Note that the format of the toolset string changed, so allow one to
pass in and thus use a custom toolset string, otherwise the default
toolset string will be generated as it was before.
Note also the Visual Studio 2017 aims to be compatible with Visual
Studio 2015 on the CRT level, so binaries built with 2017 should
work without problems with the binaries built with 2015.
We can't pass the same string to two different snapshot states since
removing one of them will free the passed string, so just create another
one for the second state.
Clamping the anchor values as introduced in commit 9a5ffcd to fix bug
777176 breaks menu positioning.
By keeping the anchors rectangle size greater than zero, we end up
deducting some positive value from the original position, so there is no
need to clamp() actually, keeping the values positive is enough and
avoids the issue with menu positioning on the menubar.
An additional benefit is to make the code a lot simpler.

Since GtkTreeMenu became a private class only used by GtkComboBox, all
this test actually did was to show a ComboBox constructed with a custom
CellArea. Now that the latter is no longer possible, the test just shows
a handful of settings that do nothing. Just test GtkComboBox directly.
Currently hiding destroys the wl_surface and all related interfaces,
(including the gtk_surface1) so the next time the GdkWindow is mapped,
we don't bother to set the DBus properties. Toggle the check off so
it's actually issued again after the GdkWindow gets a gtk_surface1.
