ba37e87dab Add UserBufferManagementInit() 
Used to reset any state required in UserBufferManagement(). Weak default
implementation provided, which does nothing.

Also tidied up weak default implementation of UserBufferManagement(),
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.

dde838c940 Update I2S input buffering to support downsampling scheme 
Also:

- Replace defines added for I2S downsampling with existing defines.

- Remove downsampledI2S[] buffer until DS3 API is finalised.
  Samples from samplesIn[] are output instead for now.

020cf2dad7 Add DS3 to I2S input 
- I2S downsampling is disabled by default.

- I2S rate is always scaled up:
  The host may not issue a SET_SAMPLE_FREQ command so always scale up,
  and back down where the value may be a another command.
