As this changes UAVObjects both flight and GCS software will need to be recompiled to stay in sync.

what they would be on a real board. Also fixed a typo in stabilization.c which made me lose time when trying to understand the code...

sometimes thrown, and made errors not lock it up by default. It works for me,
but since this has historically been associated with lots of lock ups please
check your systems carefully.
PiOS/I2C: Make the bus by default try to recover from errors instead of locking
up
PiOS/I2C: After a bus error and clocking all previous data create a STOP
condition to make sure bus is released (note, this also requires creating a
START condition first)
PiOS/I2C: If the same event hits the I2C bus twice in a row then disregard
second one, there is no situation where we should get the same event multiple
times that matters and this gets us out really quickly to catch the real
events. I was seeing this with repeated 0x70084 which means byte transmitted.
This is related to STM32 bugs in the IRQ timings I believe.
PiOS/I2C: 1) Mask out some bits we don't care about in the event flags
2) Don't lock up if the give semaphore fails, although why it does is strange
3) Recover from bus failure through the "auto" state path instead of just
coding state
PiOS/I2C: Change the reset bus code to follow
http://www.analog.com/static/imported-files/application_notes/54305147357414AN686_0.pdf
(thanks for the reference Neontangerine). Although this may actually NOT clear
the bus the first time through, subsequent bus errors should eventually clock
it out. The up side is it is less likely to clock a bunch of 1s into an ESC
and make it run up.
PiOS/I2C: Some cleaned up code for getting a snippet of the history when
something strange happens
PiOS/I2C: Export logging information from I2C through a UAV object
PiOS/I2C: Improve the diagnostic information
PiOS/I2C: Need to handle the event 0x30084. This seems to happen between a
byte transmitted and new byte started
PiOS/I2C: Handle the NACK condition by simply going to the stopping state.
PiOS/I2C: Add a new NACK state to handle sending the STOP signal after a NACK
following the STM documentation. Other error conditions still are not dealt
with.
PiOS/I2C: Should handle the NACK condition from all the write cases. Need to
think about read cases

Changes in ahrs.c for new initialization and to fix issues with outdoor algorithm. The changes in ahrs.c are pretty messy, but committed mostly to get the code to Peabody for more extensive restructuring of ahrs.c.

to fix compile errors.

Flight: Create PositionDesired (the active waypoint) UAVObject and make the FlightSituationActual no update since it not used.
Flight: New velocity desired object that passes information between the look computing the desired velocity and the PID loop to get it (updated at different rates)
UAVObjects/PositionActual: Remove unused GPS fields
UAVObjects/PositionActual VelocityActual: Split the velocity into a separate object. ALso make sure all the information telemetered around is in cm to avoid using floats.
UAVObject/GuidanceSettings: New guidance settings object for the guidance module
Flight/Posix: Add the new objects to the Posix sim
Flight/Guidance: Computes a desired velocity based on position error than runs a PID loop to control roll and pitch to achieve that velocity. All distances are in cm, and updated the PositionActual fields to reflect this and use int32.

Removing some Experimental and Incomplete Modules and their UAVObjects not suited for 1.0
- they will be moved into an experimental branch:
Navigation : experimental code only
FlightSituation: experimental code only
Guidance : preliminary draft - possibly to be replaced by peabody124 position hold code if finished in time.

Creating GuidanceModule together with PositionDesired UAVObject (as discussed),
so dschin and me can work on it :-)
Will compile and (on sim_posix) execute, but PID logic is yet untested and preliminary.

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.

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.

This object is not yet populated or used. This
will soon hold the raw position data from the GPS
receiver. PositionActual will be converted to
hold the computed position from the AHRS.
Contents of this object are still subject to change.

This is to align the object names to matches the UAVObject
architecture doc. No functional changes.

The modules were disabled for some reason in r1172.
This just turns them back on for the real targets.
