Fix broken NO_SERIAL_LINK build

Support STATUSTEXT_LONG

On desktop (Ethernet connection), the ground unit pushes UDP directly, which makes the use of an actual "Link" not possible. Instead, I've moved all of Taisync support to a "manager" owned by QGCToolbox.
Added a Taisync settings with some basics already wired and running.

Three components for better testing

Prevent counter overflow

16 RC channels

Support parameters from multiple components

Support new ArduPilot bootloader PID/VIDs

Fixed the core MAVLink receiver. Among other things, it wasn't accounting for fragmented messages.
Fixed code that monitors messages received (and lost)
Added a section within the MAVLink panel to show the current status (for the current vehicle)
Remove some old, unused exposed interfaces

Back up further from end of file to handle more cases

ArduPilot ChibiOS support

Previously the first activeChanged signal got lost because it was not connected yet to the LinkInterface which resulted in a link incorrectly shown as inactive.
