Merge upstream 3.0.1 into Feature/websocket reborn

[relyt29]

Notes:

I have this working, tested in the usual way.

SIGNAL PHONE CALLS SHOULD AND OUGHT NOT TO WORK!!

texting messaging via data channel does work

I disabled redphone server registration. If someone else wants to work on figuring out how to make redphone registration work when you don't have a gcmId to give the redphone server, be my guest. My priority is making sure texting still works and that the codebase doesn't fall so far behind upstream that its no longer maintainable. Check out src/org/thoughtcrime/securesms/service/RegistrationService.java that's probably where you'll want to start.

Closes #37

If this is merged I think it will make sense to make a separate issue tracking progress getting redphone to work without GCM

Could you make it that way, that everything (even RedPhone server registration) still works if you have GCM and WebSocket is only used on devices without Google Play Services? That way we wouldn't need to maintain two separate builds and can have universal builds useful for both people with/without Google Play Services. But it would need option to force WebSocket in preferences (even if one have GCM on the phone).

@xmikos: Good point! Such a hack would be useful! Thank you f41c0r for the work. Hope this gets merged soon!

@xmikos That should be doable, I'm too busy atm, but perhaps next weekend.

Btw @f41c0r, Signal phone calls do work, only registration is stripped from the code. That means, if you are already registered with your phone number through legacy RedPhone app, I successfully called other Signal users. RedPhone allowed registration and call initiation without GCM, but it was not possible to receive calls (same here now).

@art1fa Do you mean that if i registered via PhoneLibre i should be able to make calls from the LibreSignal (websocket version) app? I ask because that does not work in my case (no gapps installed).

@thrillfall Calling to "Appstore Signal-users" works for me with the websocket Signal from f-droid. I didn't register for Redphone just for normal Textsecure.

@thrillfall From what I have tried, it seems that it will work if you have previously registered with RedPhone/Signal server with GCM. Then you can make calls even from websocket-fork, but receiving calls will still not work.
