Camera2: Do not issue autofocus cancel if preview stopped

942890667aa08cc3c1305d7ba64c1340df1219db introduced the option to not
issue autofocus cancel if the preview was stopped. Extend it to the case
where the preview is stopped because the camera was called as an intent
(ie from MMS client)

Camera2: Smart scene icons w. original artwork

These are functional replacements for the smart scene indicators
created from scratch for CM, and fully owned by the project.

I'm sure the size, border weight may need some adjustment, but
they're currently identical to the burst mode indicators in:

camera: Add metadata-based ASD

 * New cameras use the metadata callback to report the
   detected scene mode. Add support for this.
 * The asdModes array must be set for this to work, which
   should contain the ordered list of possible scenes,
   corresponding to the camera_asd_values array.

camera: Histogram, ZSL burst mode, HDR-on-ZSL

 * Optional features available on newer sensors
 * Histogram needs to be made pretty

Camera: video stabilization setting - don't default enable

This partially reverts:
https://github.com/CyanogenMod/android_packages_apps_Camera2/commit/8dc898aec74fe96b9411872eef8748727166a021

Causing camcorder crash on HLTE and probably other devices.

Much safer for devices wishing this enabled by default to set this
in an overlay.
