Remove AutoLoad support

Cherry pick virtual joystick fix from Stable

Added a transmitOnly flag to UDP config. When enabled, the socket receive buffer is set to zero such that no data is ever received. Also updated the MavlinkSettings page such that new config settings respect the setting visibility.

Updated mavlink forwarding implementation to forward all mavlink messages received on all channels onto a single UDP port. A new mavlink forwarding UDP link is created if forwarding is enabled. The mavlink settings page now has a Fact checkbox for enabling forwarding and a fact text field for specifying the host name.

Added mavlink forwarding as an option to UDP connections. Enabling this setting will cause every mavlink packet received by QGC to be forwarded on the link, with the exception of packets originating from said link.
