This header is used by waf to contain the generated version macros,
particularly using the git hash. For waf it's better to be in a separate
header since it then can keep track of changes on it a trigger
recompilation.
For the make build system, a dummy ap_version.h file has been added in
the missing/ folder so both implementations can co-exist.
Having the version macro in the config.h and consequently in the main
vehicle header means that whenever the version changes we need to
compiler the whole vehicle again. This would not be so bad if we weren't
also appending the git hash in the version. In this case, whenever we
commit to the repository we would need to recompile everything.
Move to a separate header that is include only by its users. Then
instead of compiling everything we will compile just a few files.

And so on.
Ideally for sizeof() which returns size_t we would use %zu, but that's not
implemented by our version of printf. So use %lu which should be ok in all of
our boards.
Fix warnings like this:

These happen because we are trying to set APM_BUILD_DIRECTORY to undefined

APM_BUILD_UNKNOWN

This rangefinder uses an spi device to send pulses and an iio driver
in buffer mode to get data
The data is then analyzed and the maximum pulse received is considered to
represent the echo of the pulses that have been sent. The distance in time
between the pulse that is sent and the pulse with the maximum amplitude
is used to calculate the altitude based on the speed of sound.
There is a dependency with libiio, and in order to build, there is a need
to provide a rootfs that includes libiio.a.
The other solution is to build dynamically after having updated the rootfs
to use on compiled with a more recent toolchain and include libiio
