DMA-based ADC input (microphone, analog sensor) (#1101 )

Mimics the I2S/PWMAudio/Stream interface for ease of use.

* Fix non-32b DMA size transfer calculation in ABM
* Rename wasHolding to isHolding in the I2S/PWM
  It is the **current** number of bits left, not the past number.
* Add commented microphone example
* Add docs
