Andrew Tridgell 39de7be71f AP_UAVCAN: added CAN_Dx_UC_ESC_OF parameter 
this allows for an offset in ESC numbering for much more efficient CAN
bandwidth usage.

For example, on a coaxial OctoQuad quadplane the ESCs are typically
setup as outputs 5 to 12. An ideal setup is to split these over 2 CAN
buses, with one CAN bus for the top layer and the one bus for the
bottom layer (allowing for VTOL flight with one bus failed).

Without this offset parameter you would be sending RawCommand messages
like this:

bus1: [ 0, 0, 0, 0, ESC1, ESC2, ESC3, ESC4 ]
bus2: [ 0, 0, 0, 0, 0, 0, 0, 0, ESC1, ESC2, ESC3, ESC4 ]

this is very wasteful of bus bandwidth, with bus1 using 3x the
bandwidth it should and bus2 using 4x the bandwidth it should (the
above will take 3 can frames for bus1, and 4 can frames for bus 2)

With this patch you can set:

CAN_D1_UC_ESC_OF = 4
CAN_D2_UC_ESC_OF = 8

and you will get this on the bus:

bus1: [ ESC1, ESC2, ESC3, ESC4 ]
bus2: [ ESC1, ESC2, ESC3, ESC4 ]

that takes just 1 can frame per send on each bus

ArduPilot is the most advanced, full-featured, and reliable open source autopilot software available. It has been under development since 2010 by a diverse team of professional engineers, computer scientists, and community contributors. Our autopilot software is capable of controlling almost any vehicle system imaginable, from conventional airplanes, quad planes, multi-rotors, and helicopters to rovers, boats, balance bots, and even submarines. It is continually being expanded to provide support for new emerging vehicle types.

The ArduPilot project is made up of:
