Beat Küng 25cb400da9 EKF: remove Ekf::KHP and move KHP to the methods where it's used
Everywhere where KHP is used, it is first completely reset, thus making
it unnecessary to keep it as a class member.

This saves 2.3KB RAM.

Stack sizes don't need changing, since there is already a function
Ekf::predictCovariance(), which needs around 3KB of stack and is called
close to where the fuse* functions are called.

Roman c5f750dcca ekf reset: more granular reset / timeout strategy for gps fusion
- if both gps position and velocity measurements are rejected for 7 seconds
do a reset
- if only gps position measurements are rejected then wait for 14 seconds
as we still have velocity measurements to constrain the drift in position
- introduced ecl internal parameter for the timeout

Roman 238d947239 proper handling of position and velocity reset
- position reset method was returning before the actual delta values
were written and applied to the output buffer
- apply reset delta also to the output sample which was already taken out
from the output buffer, otherwise the complementary filter solution is
offset from the ekf solution

Beat Küng 73b8ac954d 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)

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.

Perform the innovation consistency check on all axes first and exit if any axis fails. Reduces the likelihood of bad magnetometer data corrupting the attitude estimates.
