This allows SPI to be entirely interrupt driven, with callbacks for
completion. It's not tested yet...

This does "something" in radio test mode, appearing to generate a
730MHz signal.

The STM32L151 has several SPI busses, and we want to use more than
one, so add a 'bus' parameter to the SPI interfaces. To avoid wasting
time on AVR and CC1111 processors which only use one SPI bus, elide
those parameters from the actual functions by wrapping them with
macros.
Configuring chip select is now all macroized so that each chip can
have its own version, allowing the STM to share the various SPI device
drivers with the cc1111 and avr processors. Note that only the M25
driver has been ported; porting the others is 'trivial', but not
necessary at this point.

This allows a single user of a DMA channel to reserve it for use
without needing to lock the mutex; this is required for DMA from the
ADC to work on megametrum as it wants to start DMA from an interrupt
handler, which cannot block on a mutex.

Some architecture specific stuff needs to use core altos code, so
create new ao_arch_funcs.h files per architecture that get pulled in
at the end of ao.h
