Bug#1016180: transition: gnome-desktop 43

[Jeremy Bicha <jeremy.bicha@canonical.com>]

Control: tags -1 -moreinfo

gnome-books has been removed from Testing so can be ignored. now.
budgie-control-center is fixed in experimental and will be uploaded to
Unstable promptly once the transition begins.
chatty has a merge proposal in Salsa. [1]
And I'll do a Nautilus upload once the transition begins.

The gnome-desktop library has a fairly strict dependency on
gnome-desktop3-data. This means that it won't be able to smoothly
migrate; everything needs to migrate at the same time.

This transition is basically complete in Ubuntu. We got stuck because
some packages depend on libx11 which is stuck in kinetic-proposed
because of an autopkgtest issue which isn't affecting Debian.
