includes these changes:
add header to quadruped.lua example
quadruped.lua loses unnecessary pwm array
minor formatting fix
correct quadruped comments re servo connections
quadruped.lua replaces /2 with x0.5
quadruped.lua loses servo_estimate arguments
with multiple airspeed sensors and airspeed affinity in EKF3,
it is possible to have switched over to a lane not using the
primary airspeed sensor, so AHRS should know which airspeed
sensor to use, i.e, the one being used by the primary lane.
this allows the EKF core index to be used to select a GPS/baro/mag
instance. This is an alternative to GPS blending that allows EKF lane
switching to be used to select the right combination of GPS and IMU
add logging to XKFS message
TODO : Port lane switching logic from EKF3 to make use of these terms
Since both share the same NKF3 log structure, needed to do this.
Just log 0 as of.
`strndupa` is only available when using the GNU GCC suite.
With this definition is possible to use the MUSL compiler.

musl implements `sched_*` following the posix standard,
where `sched_setschedule` is used for process scheduling.
Linux implementation defines `sched_*` functions based in
the thread scheduler and not with the process.
Using `pthread_*` should be used to follow such standard.

This can be fixed by using `pthread_setschedparam` and requesting the current
thread id via `pthread_self`.
