Camera: Restart preview when changing preview resolution

On Cameras that has widescreen photo support, it is necessary to
restart the preview whenever the preview resolution is changed.
The Video Camera code already does this when switching from 480p
and 720p.

Camera: Allow a device to request the focus modes at build time

By default, if a HAL supports touch-to-focus, mode selection is
disabled. Make that an option for devices where manual modes
work better without TTF (Macro, for instance)

Avoid calling the set methods when the areas are null, this causes
issues with some camera HALs

   to statics in the Util class instead.

Camera : Restart preview when the snapshot aspect ratio changes

Restarting of preview is required when user changes to a different
picture resolution whose aspect ratio is different, as the buffers
need to be released and requested again with new preview resolution.

Camera: Fix issue with preview callback buffer size mismatch.

If android.hardware.Camera.PreviewCallback  is implemented in
the application layer, then the callback buffers will be delivered
to the application. A crash was seen in switching between picture
sizes with different aspect ratios.When aspect ratio changed the
preview was restarted after some delay. This was causing intermediate
buffers size to not match with the newly selected size.
Fixed this by calling stopPreview immediately after the aspect
ratio changed. Start preview will be called at a later point.
