Update ecl library reference.
Update default parameters

As a current workaround we need to wait some time after publishing a
mavlink log message in order for it to arrive in QGC.

Without this wait, we end up saving the old parameters on Snapdragon.

This fixes the clock used for pthread_cond_timedwait properly.

It's enough to have the check_submodules.sh script. The rest needs to
go.

This fixes a bug that the mainapp on Snapdragon uses 100% CPU.
