camera: Add support for ZSL on new Samsung devices

 * The camera driver on new Samsung devices requires that we send a
   magic command to the hardware in order to get ZSL behavior with
   continuous preview. On previous devices, this worked as long as the
   "cam_mode" parameter was zero (instead of null) and "camera-mode" is
   set to 1. On JF, we need to do all of these things.
 * The command we need to send is 1508, but I do not know what this
   value actually corresponds to. It was discovered by reverse
   engineering.

Camera: Fix for stretched preview in front camera

Stretched preview is observed due to front camera's mount angle.
This patch resizes preview frame using aspect ratios so preview is not
stretched when using the front camera in still and camcorder mode.

Camera: Fixes stretched preview in camera application

- The preview screen nail is getting set with the
  preview frame layout size, which depending on the
  preview resolution might lead to aspect ratio
  mismatches.

Camera: Updates preview screen nail correctly

- Querying the width and height of the screen nail
  currently will return the render width and height
  which in turn depend on the preview frame layout
  size. In cases where both sizes match the screen
  nail will not get updated properly. Instead of
  using the render width and height this change
  uses the actual size of the nail itself.
  This way changes to the resolutions are
  recognized properly and the nail is updated.
- This patch also removes 'updateCameraScreenNailSize()'
  and extends the functionality of 'startPreview()'
  in order to update the screen nail for the cases
  where the preview and the nail size don't match.

Fix preview state machine after it's restarted due to ratio changes

The camera state was being set to PREVIEW_STOPPED by the restart,
and the lack of a completion message was leaving it in that state,
breaking other checks down the line (changing scene/balance modes,
for instance, failed miserably)
