Lucas De Marchi 2240eb6b4f Move __STDC_FORMAT_MACROS to build system (#174) 
__STDC_FORMAT_MACROS changes the behavior of inttypes.h to allow
defining format macros for printf-like functions. It needs to be defined
before any include is done, otherwise due to include chains and header
guards it may not take effect.

Instead of defining it everywhere it is used, let the PX4 build system
to deal with it.

This allows the filter to adapt to variations in GPs quality.
The range of adjustment in observation noise is limited to the range between a lower limit set by the GPS observation noise parameter and an upper limit set by the no-aiding observation noise.
