Title: Simplify encoder interface--remove EncoderFrame2 function 

simplify encoder interface configure
1. remove EncoderFrame2 from interface function.
2. take a SSourcePicture instead of an unsigned char* in EncodeFrame and PauseFrame function
3. only one source data as input.if the user sets multiple spacial layers, VP will do down-sampling
