I noticed the doco on the Rover discourse page for LOG_BITMASK was
incorrect so I have fixed up a number of doco/comments so they
auto-generate the doco correctly for the wiki. There is no actual
code changes in this commit.
The EKF's getPosNED returns a vertical position relative to the EKF origin but previously this function was using it as if it was relative to ahrs's home
this adds non-turbulent wind support for the built-in simulators. I
added it primarily for quadplane testing, but it should also be useful
for multicopter navigation testing.
In several places we use functions like asprintf() that are only
available in libc when _GNU_SOURCE is defined. Always define _GNU_SOURCE
since we always want to use them.
This fixes the build on Windows using cygwin.
