* Deal with missing parameters on Solo

* Fix trigger set

During tests, if the airframe was configured to be an 'X' type
we showed just 'X' on the airframe type. It's correct but a
single letter - specially an X - made users think that it was
a error code, not the airframe name. So, because of that, also
show the vehicle type - a wrong value, but elucidative for users.

This mechanism automatically queues data into the correct thread where necessary, otherwise the method is invoked directly with low overhead.

At the same time remove the UDP socket event workaround. It is not a problem.

This way we don't need macro-magic to deal with
different operating systems and compilers.
