Add emptty and relevant configs to replace weston-init. This is a modified
version of the proposal I made to oe-core to get around a sequencing bug that's
been around for a while, but has recently become an issue for us.

As it stands weston-init has no idea what drm devices it should wait on or bind
to. We could introduce a udev rule to track tidss and pvrsrvkm registered
devices and introduce systemd dependencies around those new .device units, or we
could add a proper display manager that's already capable of waiting for drm
devices and has the potential to handle hotplug events in the future.

I'm preferable to the second option instead of making rules and modifications to
the service file for multiple platform configs.

This series adds emptty as a display manager and converts our bbappend for
weston-init to a stand alone version of weston-init named weston-init-arago.
This package has the required config files for emptty to automatically login the
weston user like weston-init does.

This does remove the weston systemd unit and global weston socket. This was
probably for the best as it was not really standard behavior. It just made it
"easy" to run arbitrary GUI applications as root, which is never advised.

Randolph Sapp (2):
  emptty: add version 0.13.0
  weston-init: weston-init -> weston-init-arago
