[xenial] Implement Halium in Ubuntu Touch

[UniversalSuperBox]

Halium promises to unify our Android hardware compatibility layer with other GNU/Linux distributions. It provides a port-once, run-anything interface, so one developer's successful Halium port will open a device up to Ubuntu Touch, Plasma Mobile, and any other distributions that choose to use it.

In order to consider a 16.04 image for release, Halium will need to be fully implemented in Ubuntu Touch. This includes:

• Ensuring that Halium upstream is in a stable state
• Packaging Halium for Ubuntu
• Any other Ubuntu-specific implementation details

Fix Released!? For real? Nice (assuming I understood this right :) ). Where's the press release or something? I mean this is big news and it is being promoted, right?

I also assuming Halium should be released when closing this thread. I wonder too...

Current issues with Halium and our core devices:

• N5 libhybris issues for Nexus 5 (hammerhead) Halium/projectmanagement#8
• FP2 libhybris issues for Fairphone 2 (FP2) Halium/projectmanagement#10
• OPO (no tracker yet)
• M10 HD (no tracker yet)
• M10 FHD (no tracker yet)

As long as these problems are not solved, Halium cannot be considered stable enough for UBports. So, this ticket must be re-opened.

Due to the possibility to boot with upstart instead with systemd I don't see this as a blocker anymore. Opinions?

I feel that #404 is possibly a duplicate of this now. Would you agree, @Flohack74?

Another tidbit, I don't think this blocks OTA-4 in any way so it could be moved to a new milestone.
