ba37e87dab Add UserBufferManagementInit() 
Used to reset any state required in UserBufferManagement(). Weak default

and added a header file to define both function protypes.

1bd7dcf168 Add I2S resync to LRCLK logic when CODEC_MASTER=1 
In CODEC master mode, the I/O loop assumes L/RCLK = 32bit clocks.
Check this every iteration and resync if we get a bclk glitch.
