this fixes an issue where an airspeed sensor that becomes unhealthy
can have an undue effect after the sensor becomes healthy again.
In a recent flight log the MS4525 airspeed sensor went unhealthy for a
few seconds, and at the same time gave a reading of 12m/s. The plane
was flying at 24m/s. While the sensor was unhealthy the code correctly
switched to the airspeed estimate, which was fine.
When the airspeed sensor become healthy again the IIR filter in
AP_Airspeed meant that the speed read at 12m/s initially, then came up
to 24m/s over a couple of seconds. This caused the VTOL motors to come
on for a few seconds.

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach
Thanks to assistance from Lucas, Peter and Francisco
Instead of calling a special method in the device, just use be16toh()
which is implemented for all platforms in our special sparse-endian.h
file. It has the advantage of using a special type for different
endianness and makes no assumption we are running on LE.

We currently check examples are buildable with waf which doesn't need
the libraries to be specified in a make.inc file. Having the makefiles
there is misleading since people try to build and realize the build is
broken.
