* Regenerate from XML
* Write code for function headers I put in Mavlink.h (see -Message Status Codes-, I wrote one in Mavlink.c as an example). Also, functions with no ack arguments are assumed ack=NO_ACK.
* Hard code mavlink uart ID into module with #define MAVLINK_UART_ID
* Remove receive_Ack function(atlas and compas state machines will handle the packets in real time)
* Remove _resend_message (atlas and compas state machines will have acks integrated into state machines and will wait for acks before transitions, or will otherwise restart their processes if they timeout)
Added Mavlink private functions, formating changes.
