1) Added nack counter monitoring
2) Made timeout for getting semaphore in I2C user space code use the one from
driver and record timeouts. This does not influence timeouts in the non
FreeRTOS case
3) Remove case block from the error handler so that all bus errors reset the
i2c interface

projects which messed up a timer on OP and serial on PipX. Now this is only
changed for AHRS. Ideally wouldn't even change for that but then ADC runs too
fast and we get a lot more CRC errors for dealing with all that data.

ActuatorSettings although for PWM aircrafts it should be done exactly as before
Actuator: Store the update times and maximum update time
OP-14 I2C: Start tracking short history of events and states in driver for
logging
OP-237 Flight/Actuator: Support for I2C based ESCs
OP-237 MK_ESC: Send all four motors as one atomic transfer
OP-237 Flight/Actuator: Allow channels to be mapped to MK I2C interface. Currently
mixer channels are either PWM or MK but in the future this will change to
support more than 8 channels.
OP-16 PiOS/I2C: Further work to try and make I2C more stable, mstly special case
handline in IRQ
OP-237 I2C ESC: Support for Astect 4 channel ESCs
OP-237: When the I2C Actuator write update fails track this
OP-237 Actuator Settings: Change the way motor types are selected to keep that
information more appropriately within ActuatorSettings instead of MixerSettings
Also make motors stay at or above neutral when armed and throttle > 0

tasks directly update a flag for each module (which they register) and when all
flags set clear the watchdog then.

priority preempts) and adjusting the priorities around to be more sensible.

but not having telemetry causes a reset. If the buffer got full enough it
would never start to transmit again.
Note: also making Telemetry non-blocking

before because if transmission got NAK then sending would stop. Now the next
time data is added to the buffer a new send will be attempted.
fifoBuf: in clearData just set the read pointer to the write pointer. This is
safer for multiple people accessing it assuming the reader will be clearing it.

required for longer sequences, Need to deal with when it happens
inappropriately better.

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

and starting transmission again. This should address the bootloader locking up
on verify.

configuration structures are const which keeps them in flash instead of ram.
However the library needs to declare them const for the compiler to work.
