Telephony: Fix NPE while opening allowed number.

Trying to edit existing allowed number caused NPE:

mNameField and mNumberField setText caused TextWatcher afterTextChanged
event while mButton is still null. So set mButton before setTexts.

[2/3] Telephony: Incoming Call in Background

Patch ported from 4.2 which was done by our lovely HCP. A
very popular one so we bring it back and adapt it to 4.4

Allows user to set that Incoming Call UI will remain in background
if screen is on. Instead, a notification is added to StatusBar, which
can be used to bring up the Incoming Call UI. Ringtone and vibration
still occur as per system settings.

This has the same effect as apps marked as "immersive". It prevents
the incoming call from backgrounding the current activity.

PS: reorder settings a bit
