Camera: Disable Camera Launcher when both Front and Back sensors are not detected

Instead of checking only back sensor, this change checks both Front and Back sensors
at the time of first time boot up and then if no sensors are present, disable all
camera activities/CameraLauncher.

Camera: Cleanup hardware key handling

* Fix power shutter behaviour in camcorder mode
* Disable volume change while in panorama mode, volume buttons should only
handle camera operations while in the camera
* Add camera/power/volume key shutter handling in panorama mode

On devices with a hardware camera key:
* Disable power & volume shutter features
* Volume buttons control the zoom

On devices without a hardware camera key:
* When power shutter is disabled, volume buttons control the shutter (like AOSP)
* When power shutter is enabled, volume buttons control the zoom

Camera: fix crash on screen off-on on preview screen

Some Camera HALs don't like stopPreview being called with
setPreviewTexture set to null.

Problem occurs on:
 - Acer A700 (Tegra 3) - always
 - Samsung I9082 (Broadcom) - sometimes

Camera2: actually fix ArrayAdapter on MoreSettingsPopup

Like CAF already discovered googles attempt to handle the
ArrayAdapter listview does not work as expected if the scroll view
is larger then the screen. CAF tried to fix it with this commit on landscape
view

https://github.com/SlimRoms/packages_apps_Camera2/commit/c5b0bfcf2340f02ca65ad3d8c08b5c7d74776ea1

which is only a dirty workaround fix for the actual root cause and only works
on landscape partly and if the complete layout is loaded new completly not.

Whatever to fix it we need to override and set getItemViewType(int)
and getViewTypeCount() to actually allow to handle propper two row
layouts like it is needed in MoreSettingsPopup (either checkbox layout
or menu layout). The actual detection which type of preference
we need is handled in getItemViewType.

Camera2: fix possible NPE on configurationchange

Step to reproduce:
- open camera from lockscreen
- during it opens turn your phone
- result: crash

Due that the camera is in middle of the initialization mParameters
is null at this point. Just check against null to prevend the crash.
The correct resizing happens so or so during the ongoing initialization

Thanks TJKV from xda for the report

Camera2: add option to prevend autofocus cancel if preview stopped

There are camera HALs which cannot handle the autofocus cancel call if the preview
stopped in startPreview(). Add an option for this HAL's to do not cancel autofocus in this cases.
