The DRDY signal from the magnetometer is connected to PB8

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

the side effect of making the CPU utilization on the

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.

and the quality of their signals.
NMEA GSV sentences are now parsed. The full set of GSV data

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.

The transition from the ADDR state to the read state
was broken for non-final reads. The FSM diagram was
also wrong for this transition.
Since reads are always the last transaction in a sequence
in our current usage, this doesn't actually fix any known
bugs.

Since the i2c bus is bidirectional, there are certain
states (eg. part way through a read) where the slave
device is in control of driving the SDA line.
On a cold start (power on), the slave devices are all
quiescent and will not drive the bus. However, on a warm
start (eg. watchdog or jtag restart), it is possible that as
the CPU boots, the slave device may be holding the SDA line
low. This is a bus busy condition and will prevent the I2C
bus master in the CPU from being able to seize the bus during
init.
The fix for this is to clock the i2c bus sufficiently to ensure
that the the slave device finishes its transaction and releases
the bus.
Once the slave has released the bus, the bus master can properly
initialize and assert a STOP condition on the bus.

The STM32 I2C block has a number of errata associated with it.
These errata are primarily related to timing sensitivities between
the peripheral and the interrupt handler. In particular, the
correct generation of the stop bit relies on the I2C IRQ running
immediately and not being held off for any reason.
NOTE: The I2C interrupts must be the highest priority IRQs in the
system to ensure correct operation.
I2C protocol is now implemented as a formal state machine.
See: stm32_i2c_fsm.{dot,jpg} for FSM description.
I2C init is now expressed by const initializers in pios_board.c
for both OP and AHRS boards.
I2C device drivers (ie. bmp085/hmc5843) now pass in const arrays
of an unlimited number of bus transfers to be done atomically.
The I2C adapter driver now handles all bus-level locking across the
list of transactions. Generation of start/restart/stop conditions
are handled automatically over the list of transactions.
Timeouts have been removed from the API for now. May be added
back later.
This driver has run error free on both the OP and AHRS boards for
up to 48hrs but it still sometimes fails earlier than that on the OP
board. There is another possible set of improvements to the driver
that could employ the DMA engine for transfers of >= 2bytes. This
change would reduce the timing sensitivities between the peripheral
and the driver but unfortunately, both the SPI and I2C interfaces
share the DMA1 engine. That means only one of these two peripherals
can use the DMA engine and right now, SPI between OP and AHRS is
already using it.
Failures are currently fatal and will lock up the CPU. This allows
useful information to be obtained in the failure cases.
