InCallUI not dismissing after end call is clicked.

In MT InCallScreen, the customMessage dialog
which appears when user tries to reject a call
with message, is not set to null when user
cancels the dialog.
InCallUIActvity is not finished if there is any
pending dialog which is not null and hence this
issue is seen.

Set the dialog variable to null once the dialog
is cancelled by the user.

IMS-VT: Peer Resolution feature and split screen fix

-Implement Peer resolution feature. Change far end size
 based on peer resolution

-When VideoCallPanel's size changes, its children need
 to update their size accordingly. This enables the farend
 view ie.video_view to resize correctly after background call
 is dropped, in multiple call scenarios
