 Camera: Remove AF UI when faces are detected in photo ui

 AF window does not go away when faces are detected while
 capturing the images.This is because AF is not cleared
 when faces are detected in photo ui.

 The fix is to clear AF window by calling AF succeed
 when faces are detected in photo ui.

Camcorder: Switch video torch when preview focused

- Currently, video torch switching is not determined
  properly. When user enables and disables flash mode
  checkbox, nothing happens. Also, if video torch
  is enabled and switching to Camera and back to
  Camcorder mode, torch doesn't lights up.

- Adding a local variable mPreviewFocused to track
  the preview window focus state should fix the issue.

Camera: Don't do cancel_af till all CBs are received in burst shot

Doing cancel_af in the first jpeg CB while
burst shot is going on, is changing the
camera state to IDLE and allowing next
takePicture() which is resulting in crash
as this call reaches HAL when camera is in
picture taking state.

Camera2 : Reset mSnapshotInProgress if recording stopped.

If recording stops while snapshot is in progress, we might not get
jpeg callback because cameraservice will disable picture related
messages. Hence reset mSnapshotInProgress flag so that we can take
liveshots in the next recording session.

Camera: Dont reset camera state while capture is in progress.

While capture is in progress and if we get autofocus event,
currently we reset the camera state to IDLE blindly. This is
resulting in app exception because it will trigger another
takepicture and lower layers will return error.

Camera2: Check mCameradevice before setting skinToneEnhancement

Null pointer exception in app is observed when we open camera

mCameradevice will be null by the time handler thread gets a

Update settings pref values when BSM is not auto.

When BSM mode is set to a value other than auto, flash mode, white
balance and few more settings will not be based on user preferred
settings. So mParameter object will have default values. Updating
those values in the list will over write the preferences.
To preserve settings from preferences, we need to pass the same
values.

- This reverts change If4047860.

- Simply using preview size instead of picture size

  avoiding tricky overwriting aspect ratio.

  is calculated based sometimes on preview size
  ratio and sometimes on picture size ratio.
