34f0af25cc AP_TECS : Improvements and bug fixes to feed-forward throttle demand 
This fixes a bug in the feed-forward throttle that prevented the bank to throttle compensation from working properly during descents.
It also adds bank to throttle compensation to the non-airspeed sensor throttle algorithm.

0f72eae216 AP_Camera: removed 3 camera trigger types that do not work 
the trigger by wp distance, trigger with throttle off and trigger a
transistor all don't work, and are not structured correctly, plus are
dangerous.

The existing relay support can (correctly!) handle the resistor case
without hard-wiring a pin. The "turn off throttle to trigger" idea is
badly broken, it would crash a copter if it worked. We can make it
work properly on planes if there is demand. As it was it didn't work
anyway. 

The triggger by wp distance method was broken, and had no way to
initiate a trigger anyway

21859f9364 RC_Channel: fixed dead_zone for range channels 
The dead_zone was being used inconsistently, used in PWM space in one
place, and in control output space in another.

The fix required us to move the index number of the RC channel eeprom
value for RCn_DZ, as users will have a throttle deadzone of 3 set in
their eeprom due to a bug that Randy just fixed that caused the value
to always be saved to eeprom. In plane we then need to fix the
deadzone for the throttle to be 30

this fixes issue #303

Thanks to Soren Kuula for spotting this!

9959f6b2df AP_Camera: removed incorrect mavlink sends 
these sends did nothing, as MAVLINK_COMM_3 is not connected to

the serial port was non-blocking it would corrupt the packet.

If we needed something like this it would have to use the MAVLink
packet queueing logic we use elsewhere

d3ea88e8c7 AP_HAL: resolved -Woverloaded-virtual warning 
the function:
virtual size_t AP_HAL::Print::write(const uint8_t *buffer, size_t size);

was hidden in all derived classes by their
virtual size_t write(uint8_t) = 0; implementations.

To solve this, a non-virtual write(const uint8_t *, size_t) that calls a
virtual write_implementation was added.

This isn't necessary atm, because the derived classes don't call
write(const uint8_t *, size_t), BUT this decreases the apm2-quad Program
size by 40 bytes :D and removes warnings.

26b7de668a AP_Param: fixed parameter save bug 
This bug affected parameters where the defaults are overridden in the
object constructor. For example, a PID object may have a default value
for PID_D of 0.0, but have a constructor based default of 0.2. If the
user tries to set the value to exactly 0.0, then the set wouldn't happen,
as the value matches the value in the object default var_info[]
table. 

This change ensures we force a save to eeprom if the value is changing
from the current value, regardless of the var_info[] default.

Thanks to Tom Coyle for finding this bug!

opposite direction.

10ecffce01 APM_Control: ROLL and PITCH controllers 
These changes reduce height variation in turns and improve
robustness. the specific changes are:

1) Linked roll and pitch integrator protection to the final output
value so that if final output is on upper limit, the integrator is
prevented from increasing and vice-versa. This improves wind-up
protection.

2) Modified rate feedback in roll and pitch controllers to use body
rates rather than Euler or earth rates.

3) Changed the roll to pitch compensation to use measured roll angle
and estimated airspeed to calculate the component of turn rate
(assuming a level coordinated turn) around the pitch axis. This a
mathematically correct calculation and will work over a range of bank
angles and aircraft with minimal (if any) tuning required.

4) The integrator in the roll and pitch loop is clamped when the
estimated speed is below the minimum FBW speed

5) The noise filter in the pitch and roll loop has been changed to use
a FOH discretisation. This gives improved noise rejection and less
phase loss when compared to the previous filter that used a ZOH or
equivalent discretisation.

This has been flown on the rascal in the SITL and on a X-8 with
limited flight testing. Initial results have been encouraging with
reduced height variation in turns.  Compare to standard PIDS, the
revised pitch and roll controllers allow the use of rate feedback
(effectively the same as the old D term) without beating the servos to
death.  The bank angle compensation in the pitch loop works
effectively over a much larger range of bank angles and requires
minimal tuning compared to the old calculation.

YAW CONTROLLER

Currently testing the a 3-loop acceleration autopilot topology for the
yaw loop with feed forward yaw rate for turn compensation. This 3-loop
topology is commonly used in tactical skid to to turn missiles and is
easy to tune. The following block diagram shows the general signal
flow

Note that the acceleration measurement has to pass through an
integrator before it gets to the actuator. This is a important feature
as it eliminates problems of high frequency noise and potential
coupling with structural modes associated with direct feedback of
measured acceleration to actuator.

The high pass filter has been inserted to compensate for airspeed and
bank angle measurement errors which will cause steady state errors in
the calculation of the turn yaw rate.

The yaw controller flies SITL well, but hasn't been flight tested
yet. It can be configured either as a simple yaw damper, or the
acceleration and integral term can be turned on to allow feedback
control of lateral acceleration/sideslip.

TO DO:

Need to reduce number of tuning parameters and provide consistent
naming Need to provide guidance on tuning these loops with definitions
for all the gain terms.  Need to check signs and units into and out of
lateral loops.

DESIGN DECISIONS PENDING:

1) Can we remove the noise filters? Provided the mpu6k noise filter is
running they are of limited benefit given the 25Hz Nyquist frequency

2) If we do remove them and rely on the mpu6k noise filter, what is
the apprporiate default cutoff frequency for plane use. 20Hz is
probably OK for most setups, but some noisy/high vibration setups
would require as low as 10Hz

3) The inverted flight logic looks like a crash waiting to
happen. It's problematic to test and even if implemented correctly
would still crash a plane with poor inverted flight capability. We
should either implement it properly and fully tested or delete it.

205397d030 APM_Control: Modified calculation of bank compensation rate offset to prevent climb if speed > max fbw speed

bank compensation rate offset between the min and max fbw speeds. This
