Andrew Tridgell 8a2f1fdb3d AP_Airspeed: fixed airspeed filtering issue 
this fixes an issue where an airspeed sensor that becomes unhealthy
can have an undue effect after the sensor becomes healthy again.

In a recent flight log the MS4525 airspeed sensor went unhealthy for a
few seconds, and at the same time gave a reading of 12m/s. The plane
was flying at 24m/s. While the sensor was unhealthy the code correctly
switched to the airspeed estimate, which was fine.

When the airspeed sensor become healthy again the IIR filter in
AP_Airspeed meant that the speed read at 12m/s initially, then came up
to 24m/s over a couple of seconds. This caused the VTOL motors to come
on for a few seconds.

Staroselskii Georgii 3feade792a AP_Airspeed: changed default pin for Navio boards

make sense on these boards.

Lucas De Marchi cc4504e613 AP_Airspeed: fix coding style 
- replace tabs with spaces
  - remove C-style void from function arguments
  - use pragma once
  - fix pointer alignement
  - remove unused header: AP_Airspeed_I2C_PX4 - we actually use
    AP_Airspeed_PX4

Lucas De Marchi 2591261af6 Global: rename min and max macros to uppercase 
The problem with using min() and max() is that they conflict with some
C++ headers. Name the macros in uppercase instead. We may go case by
case later converting them to be typesafe.

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.

Lucas De Marchi 2c38e31c93 Remove use of PSTR 
The PSTR is already define as a NOP for all supported platforms. It's
only needed for AVR so here we remove all the uses throughout the
codebase.

This was automated with a simple python script so it also converts
places which spans to multiple lines, removing the matching parentheses.

AVR-specific places were not changed.

Gustavo Jose de Sousa d42b132507 AP_Airspeed: 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.
