CMakeLists: don't always optimize for size
...
Going forward the optimization flags should be set for a platform,
rather than for each individual module.

ekf_helper.cpp: remove unused includes
...
This fixes a compile error with GCC 5.2.0 and cross-compilation:
/usr/arm-none-eabi/include/c++/5.2.0/arm-none-eabi/armv7e-m/fpu/bits/error_constants.h:122:27: error: 'ENOTSUP' was not declared in this scope
not_supported = ENOTSUP,
The problem was that the #include <iomanip> was taken from the host system,
which conflicts with includes from NuttX (NuttX has only basic C++ STL
support)

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.
