Dr.-Ing. Amilcar Do Carmo Lucas 188dfb6936 AC_AttitudeControl: Use SI units conventions in parameter units 
Follow the rules from:
http://physics.nist.gov/cuu/Units/units.html
http://physics.nist.gov/cuu/Units/outside.html
and
http://physics.nist.gov/cuu/Units/checklist.html
one further constrain is that only printable (7bit) ASCII characters are allowed

Randy Mackay 67097c8d59 AC_AttitudeControl: use gyro_latest 
This allows moving the attitude control before the ahrs/ekf update

We continue to use ahrs.get_gyro for the non-time-critical heli
passthrough functions.  We should avoid using get_gyro_latest() unless we know there is a direct benefit because it could lead to inconsistent gyro values vs what the EKF is using.

Lucas De Marchi 831d8acca5 Remove use of PROGMEM 
Now variables don't have to be declared with PROGMEM anymore, so remove
them. This was automated with:

    git grep -l -z PROGMEM | xargs -0 sed -i 's/ PROGMEM / /g'
    git grep -l -z PROGMEM | xargs -0 sed -i 's/PROGMEM//g'

The 2 commands were done so we don't leave behind spurious spaces.

AVR-specific places were not changed.

Gustavo Jose de Sousa d49f10d2e5 AC_AttitudeControl: standardize inclusion of libaries headers 
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

lthall 1bdde31f6b Copter: Fix zero throttle flip issue Stabilize 
The problem is that the init_targets is intended to ensure the
controller doesn't build up the I term when the throttle is low. Because
it is poorly named (or used) it have been written to do something else.
Here I change it to do what the code is trying to use it to do.
