Runtime issues resolved, quick application startup and good runtime stats: 0.3% load in idle mode, 15% load showing map and UAS list. Map has a zooming issue, but should be resolvable

Fixed a bug where non-auto hold in the debug console induced 100% CPU load even when the widget was hidden

Working WP manager -> map waypoint updates. List reordering does not work yet. Next steps: List reordering, map -> WP manager updates, better waypoint graphs

Cleaned up serial port libs, activated mav visualization on map (still debugging), fixed standalone MAVLink generator

The MAVLINK_MESSAGE_LENGTHS macro can be used to detect mavlink
messages that don't have the expected length. It is done as a macro so
that projects that don't want to pay the cost of a 256 byte overhead
can avoid the check
