These are not really used. differential_pressure is just copied from the
topic with the same name.

for sdlog2 we assume no one needs the diff pressure fields and set it to 0.
We plan to switch to the new logger soon anyway.

* Reduces wasted FLASH by > 4K

* Removed PX4_IMPLEMENT_PX4_LOG_MODULENAME

* Moved implamentation of px4_log_modulename to px4_log.c

Drawbacks of the previous method: when writing to the SD card, there are
high delays in the write() call of several 100ms, every now and then. The
frequency and length of these events depend on:
- SD card
- used logger bandwidth
- bandwidth of gps data (RTCM)
Since the whole gps thread was blocked during this period, it lead to
gps timeouts and lost module.

What we do now is: publish an orb topic with queuing. This makes it async
and the logger takes care of buffering. This means it's best to:
- use high logger rate
- use large logger buffer
- reduce logger bandwith by disabling unused topics

* Updated matrix lib to 1.0.0.

* Bump matrix version.

* SF10a driver added

* Remove Sf10a driver

* Set lower range boundary to 0.01m for LPE

This was horribly wrong. Matrix is first cast into a matrix of size NxM (which is supposed to be the size of the result - NOT the starting point) so the transpose result becomes garbage. Instead make "Me" an MxN matrix as the original. Took me a whole evening to figure out this problem. Now my Kalman filter finally returns good results.

- do not exit sensors app if sensor init failed
- do not spam console if we fail over first/second gyro

For Navio2, make posix_navio2_release and use navio2.config.
