    USB rewrite


 you should be able to find that via a google search on the git commit
hash.  kuldeep is actively working with the stm32f072 and has made
significant enhancements and improvements to libopencm3 which,
unfortunately, the core developers do not trust.  they are on what can
only best be described as a "can't-cope-so-we-must-have-unit-tests"
binge, which has hugely stalled development.  my understanding is that
they feel solely and exclusively responsible for ensuring that the
ever-expanding codebase remains "stable", but have not made a push to
invite other developers to take responsibility for ensuring that
contributions remain current for a particular embedded controller.

 my advice to you therefore is to use kuldeep's work because he is
*actively* working with the stm32f072 right now, and to *not* move
from this particular git commit unless it is absolutely, absolutely
and i mean absolute 100% essential to do so.

if you need I2C i have added to stm32/f0/i2c.h some additional
#defines that enable the i2c code to compile and operate.
