Andrew Tridgell 8a2f1fdb3d AP_Airspeed: fixed airspeed filtering issue 
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.

Andrew Tridgell 8c1cf9affe AP_Airspeed: removed create() method for objects 
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

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

Lucas De Marchi f6a4a4dbe8 AP_Airspeed: MS5525: use common macros to deal with endianness 
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.

Lucas De Marchi ae53920e5b build: don't build examples with old build system 
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.
