75cf014e5d Add crypto method to get salted names for package data and APKs
This will only hide installed apps from naive attackers as the APKs are still not encrypted and even then other attacks would be possible.

However, it allows us to simplify our storage plugin API.

0f241f7d25 Ensure that we have the main key for v1 crypto
We ask the user to generate a new key, because actively asking for the old one is training bad security habits, but technically verifying the old key will also work.

38f01765ec Allow launching restore through a dialer code
* We don't show Restore in menu by default since it's
  not the best idea to restore a running system
* However, at the same time, it's good to have a way to do
  that for those who'd like to restore anyway, and the only
  current way is adb, which is not ideal
* Dialing "*#*#RESTORE#*#*" will launch the restore activity

d2a748c34a Prevent screenshots of recovery code
This is may be inconvenient for some people, but it is way more secure as screenshots can be accessed by malicious apps that look our for BIP39 codes. Better to store the code on paper.

6e838978e3 Ask for system authentication before storing a new recovery code
This will help to prevent data extraction via seedvault when somebody gets hold of an unlocked phone. However, it will not help against someone able to force you to provide fingerprints or other device secrets.
