The hwcomposer module for Android doesn't support multi-monitor well
enough for our use case yet so we give Android a large enough primary
display. This may have negative effects performance wise for the until
we disabled all non freeform stack and wallpaper related rendering on
the Android side so that only visible windows are drawn to not waste
any GPU cycles on things we don't render anyway.

Remove unused bubblewrap source

Implement simple application view

Build and load binder/ashmem kernel modules on service start

As both kernel modules are not part of the standard Ubuntu kernel we
need to build and load them at runtime. We bundle this together with
the container manager start and reuse the classic snap scripts to do
the actual build in a proper environment.

Get rid of test for the Android platform service

Network connectivity

Mount /cache and /data properly and stop bridge correctly.

Bind mount cache/data on startup from writable space

Map /dev/fuse to make Android volume manager happy

Handle window movement/resize/close on our side and not in Android

This leads to much better performance and user interaction. Resizing
still has some flickering but that is a different area of problems.

Rework kmod sym access

Improve snap pkg

If we run the management process with the AppArmor profile loaded
from snap-confine various ashmem/binder operations are failing with
permission denied errors. To workaround this until this problem
is fixed we simply unload the AppArmor profile and continue to
execute completely without any profile loaded.

LXC doesn't start the container when the configured network interface
(the bridge in this case) is not available.
