Merge lp:~mterry/telephony-service/greeter-contacts into lp:telephony-service

[Michael Terry]

Share current call contact info with the greeter.

Share current call contact info with the greeter.

When we split the unity8 greeter out into a separate process, it will no longer be able to see the user's contact database. So it will need to query the active session for the information.

Here's how this branch does that:
* Adds a custom DBus property to AccountsService that can only be read by the greeter and set by the user.
* When a call comes in and telephony-service notifies the user, it also sets the AccountsService property.
* The greeter sees the call, notifies the user and watches the currently selected user's AccountsService property for updates. If contact information is set for the current incoming phone number, it will update the notification.
* One interesting issue is that the contact photo can't be read by the greeter because ~/.local/share/evolution is not openable by the lightdm user. So when we are updating AccountsService, we also copy the relevant contact photo to ~/.telephony-service-contact-image. There are two problems with this: (1) it is readable by the world (though to be fair, the world can see it on the screen when a call is happening) and (2) if the user's directory is encrypted, it won't be accessible. The proper fix for both of these is for LightDM to provide a /run/user-style space for persistent data sharing between sessions and the greeter. But that's a separate bug, and I'm looking into it. For now, the photo in the home dir is good enough, since Touch doesn't support encrypted home dirs yet.

I added tests and manually tested on the device (which is kinda tricky, since you need several other branches to get the split greeter to be in effect -- if interested, can provide info).

This branch shouldn't hurt anything to land now, before the split greeter happens. It will just be updating the DBus field without anyone to read it. No big deal.

** Checklist **

Are there any related MPs required for this MP to build/function as expected? Please list.
- No (note that this branch is not really helpful before the split greeter lands; but it does its job fine without other branches)
Is your branch in sync with latest trunk (e.g. bzr pull lp:trunk -> no changes)
- Yes
Did you perform an exploratory manual test run of your code change and any related functionality on device or emulator?
- Yes, with split branches installed
Did you successfully run all tests found in your component's Test Plan (https://wiki.ubuntu.com/Process/Merges/TestPlan/<package-name>) on device or emulator?
- Yeah
If you changed the UI, was the change specified/approved by design?
- N/A
If you changed the packaging (debian), did you subscribe a core-dev to this MP?
- I am core-dev

[Michael Terry (mterry)]

As discussed, this strategy is back to being useful, since we'll run a telephony stack in the greeter. Please review!

[Gustavo Pichorim Boiko (boiko)]

Code looks good and after testing no regressions were found.
