Camera: Don't try to set focus/metering areas when none exist

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

Extend RESET_TOUCH_FOCUS_DELAY to 15 seconds from 3 seconds

AOSP camera resets touch focus after only 3 seconds making it an unpleasant
experience trying to focus and then reframe the picture. This patch extends the
focus reset delay to 15 seconds so users will have time to reframe before the
locked focus is dropped.

Camera: prevent camera from running away with itself when taking multiple pictures.

The problem arises when mSnapshotOnIdle gets set to true but never gets reset back to false.
The scenario this would happen would be when attempting to take another picture while a picture is being taken.

Thanks to TheUnkn0wn (XDA).

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.
