telephony: Remove "managed roaming" feature

 * This feature shows a popup to ask the user if they want to scan for
   mobile networks if the current network is unavailable. It's confusing
   and overly aggressive, and there are other indicators when this
   happens anyway. Kill it.

Revert "Do not show roaming dialog if network scan is in progress."

This reverts commit 7935b65a4ecccf42004fbef389c58133d17704ca.

Revert "Phone(MSIM): Managed Roaming support for multisim"

[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
