Subject: [PATCH 1/2] wayland/wl-shell: Make sure created window has a proper
size
The wl_shell_window construction is a bit messy, and was not properly
resizing when a window was created after a buffer was attached. This,
when the window was the dummy window in wl-paste, caused a SIGFPE as the
window was incorrectly assumed to be 0x0, i.e. size being 0.

Subject: [PATCH 2/5] display: Also set window cgroup on cgroup creation
We'd register the cgroup for a window twice, because the firs time
didn't update the MetaWindow::cgroup pointer. This meant the cgroups
were never removed.

Subject: [PATCH 5/5] cgroup: Get app info from gnome-shell when possible
Using cgroups alone for getting the app-id is flawed, as there are many
situations where the cgroup isn't set up properly, e.g. opening via
xdg-open or equivalent. gnome-shell already has a system for associating
windows with apps, so reuse this for the cgroup app info.
