Final stm32_pin_info design candidate; ADC3 support on Native.

Added an adc_dev to struct stm32_pin_info.  This was necessary to add
support for the channels on the Native which are only connected to
ADC3, but it does add a bunch of NULLs to the PIN_MAPs.

I don't think any other peripherals need representation on a per-pin
basis.  Each peripheral library will be responsible for keeping track
of related GPIO ports and bits, and we can throw #defines in to
boards/*.h for other things (e.g. BOARD_SPI1_MISO_PIN).

Fleshed out the ADC refactor and brought it more in keeping with the
new design as it evolves.

A couple of other tweaks.  Notably: waitForButtonPress() now takes a
default argument meaning "wait forever".

Removed Maple-specific documentation from core functions in io.h; this
information will need to go into the individual board docs files.
