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 e925820d90 PID: 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.

Andrew Tridgell ba83950fc4 libraries: replace constrain() with constrain_float()
this makes the type much more obvious. Thanks to Tobias for the
suggestion.

Andrew Tridgell 6123ea2dac PID: added get_pid_4500()
this is a version of get_pid() that returns an int16_t constrained to
-4500 to 4500. This will prevent overflow errors for large PID gains
in ArduPlane and Rover

Andrew Tridgell fe964fcda0 PID: change to float input/output
this makes the PID library a bit more flexible for smaller range
numbers. Note that this library is used on ArduPlane and Rover, not

James Bielman 5631f865b2 Update floating point calculations to use floats instead of doubles.
- Allows use of hardware floating point on the Cortex-M4.
- Added "f" suffix to floating point literals.
- Call floating point versions of stdlib math functions.

Andrew Tridgell 816fe9d35a PID: use NAN to flag a D reset
this saves a byte per PID for a flag, and gives us a safe way to
reset_I() without causing a spike in D

Andrew Tridgell f6fce1e238 PID: don't reset _last_error on reset_I()
resetting _last_error when you have a non-zero D term causes the D
contribution to the next call to be massively amplified. This can
cause crazy behaviour on auto takeoff in ArduPlane if you have a
non-zero D term for the roll or picth controllers

Thanks to Chris Miser for providing the tlog that allowed this bug to
be found.

Andrew Tridgell d13d117e61 APM: removed reset_I() and instead auto-reset integrator in PID library
this prevents us resetting key integrators on waypoint change, while
still preventing old integrators being used when a PID starts to be
used again

jasonshort 4ec8805216 Reverted to older PID. Restored the older filter, and removed PI command. I am no longer using PID for the quad and have switched to PIPI loops which perform much better. The D term in this class is not that great.

jasonshort 5a22080484 I am Adding A "PI" loop to the mix. This is a need for AC2. We can optimize the internals later, but I basically duped the get_PID and removed the D term internals.
