The EOC EXTI interrupt configuration was incorrectly
pointing at GPIOG pin 8 rather than GPIOC pin 15.
This was preventing the EOC interrupt from working
properly.

I2C bus errors are now recoverable. The bus is properly reset
and an error indication is now provided to the caller whenever
a bus error occurs during processing of the transaction list.
For now, the users of the I2C layer just retry infinitely on
failure. The BMP085 and HMC5843 code should be changed to
report errors to its callers to allow a more sensible retry
strategy.

AUTO transitions in the FSM are now handled immediately
after processing each newly injected event rather than only
at the end of the EV ISR.
This consolidation allows the upcoming addition of event
injection from both the EV and ER ISR contexts.

Occasionally, the I2C driver races with the STM32 I2C peripheral
at the end of a bus cycle. This leaves the bus in an errored
state and the stop condition is not properly asserted on the bus.
The polling for the stopped condition was previously implemented
in ISR context since it was expected to be nearly instananeous.
In the error condition, however, the stop condition will never
happen. The polling for this case is now done by the initiating
task (or mainloop on the AHRS) to prevent the timeout condition
from triggering the watchdog.

The info field in the pios_i2c_txn list can now be used
to provide a const string which describes the context
for this transaction.
This is very helpful when diagnosing an error that occurs
somewhere in the middle of the I2C FSM since the FSM runs
primarily in the ISR where the original context for the
transactions is no longer available in the traceback.

This makes the AHRS continually process SPI messages
while waiting for new samples to be ready. This has
the side effect of making the CPU utilization on the
AHRS pin at 99-100% (ie. we make use of all of our
otherwise idle time).

Change from using vTaskDelay to using vTaskDelayUntil to
ensure that we're trying to stay periodic rather than
just waiting a fixed amount of time after each loop of

in. Also change the velocity variance in indoor mode to lower to make it get a better attitude estimate (primarily faster convergence - probably will tweak this in the future dynamically). Finally decreased barometer variance - in scope it's actually quite reasonable, normally within +/- .5 m.

The resultant error could range from -360º -> +360º
Since this is only used for Helicopters / multi rotors, and the aircraft can rotate in any direction, I added the modulo logic so that it is now from -180º -> +180º this should now take quickest path to correct the error.

This creates a new UAVObject called GPSSatellites to hold
information about which satellites the GPS receiver can see
and the quality of their signals.
NMEA GSV sentences are now parsed. The full set of GSV data
may be split across multiple GSV sentences, each containing
info for at most 4 satellites. Once an entire set of GSV
records has been collected, the GPSSatellites UAVObject is
updated.

GPS module now updates GPSPosition UAVObject
rather than the PositionActual object. The
GPSPosition object is intended to be consumed
only by the AHRS. The AHRS will use this (and
other inputs) to compute a filtered version of
the position in the PositionActual object.
This commit will cause temporary breakage of the
GPS functionality in the GCS until the PositionActual
object is properly updated by the AHRS. Most of the
GCS should continue to use PositionActual. The only
exception to this might be any tool for specifically
visualizing the raw GPS state.
GPS.c is now only responsible for receiving a
complete NMEA sentence from the COM interface.
NMEA parsing is now factored out into NMEA.[ch]
which is where GPSPosition is now updated based
on the complete NMEA sentences obtained from the
GPS.
Latitude and Longitude are now encoded in a
fixed-point notation in units of degrees x 10^-7
to prevent truncation of precision due to encoding
into a float.

1. Added reenumeration function and call it on USB init (device will appear after reprogramming now)
2. Moved buffer.c to general flight/Libraries location
3. Removed the 62 byte transmission limitation by adding a transmission buffer
4. Sped up USB communication by increasing endpoint polling frequency
Note, that the nonblocking and blocking USB send functions are not blocking entirely correcting. The blocking calls the nonblocking, and the nonblocking blocks until the last chunk has started tranmission if it's a big transmission. The buffering I added would generalize to non-blocking nicely, but would require using the EP1(IN) callback to handle most of the tranmission. This creates a lot of issues if one function is pushing data onto the buffer and the interrupt is sending.
