Instead of requiring that the whole set of returned values fit
precisely in the ring, allow for wrap-around so that we can fetch an
odd number of ADC values. The previous version required that the fetch
amount always be a factor of the ADC buffer size.

altos/stmf0: Allocate USB buffers at startup2015-03-01T00:10:10+00:00Keith Packardkeithp@keithp.com2015-03-01T00:00:45+00:00urn:sha1:476c5b87ea0901f70fe98b581ecca9afaf957607
This lets the extra allocations used from ao_usb_alloc_buffers be
allocated before the first USB connection happens.

This was configuring the hardware wrong, and wasn't keeping the output
ring full.

altos/stmf0: Support PA11/PA12 remapping2015-02-01T15:44:52+00:00Keith Packardkeithp@keithp.com2015-02-01T15:44:52+00:00urn:sha1:8f9e192e9d1c6fab9843939ff9117f6bb3725943
Small pin-count versions of the STMF0 can remap PA11/PA12 on the same
pins as PA9/PA10. These are used by USB, so have the USB driver deal
with remapping them.

altos/stmf0: Re-implement fast ADC code for stmf02015-01-28T04:41:15+00:00Keith Packardkeithp@keithp.com2015-01-28T04:41:15+00:00urn:sha1:8ca1f234586225caea1040bc229b63491dadc1cb
This creates a ring buffer for ADC data so that ADC fetching can run
in parallel with other activities.

Sets up the stm32f0 CRC hardware, exposing inline functions to access
it. DMA access is possible, but usbtrng can't use that.

altos/stmf0: Remove remaining stm32l bits from stm32f0 code2015-01-27T17:36:19+00:00Keith Packardkeithp@keithp.com2015-01-27T17:36:19+00:00urn:sha1:79f3434013650fe4e3d76e5eb56a10000ee34249
These were left over from the stm32f0 initial implementation work; now
it's more useful to list only the bits which are valid.
