canbusload: Add exact CAN frame length calculation (including bitstuffing)
This adds an algorithm for calculating the exact number of bits a CAN
frame occupies on the bus and uses this algorithm in canbusload. It
also moves the other methods for CAN frame length calculation, already
present in canbusload, to the new file.
The added algorithm calculates the exact number of stuffed bit in a
CAN frame. Note that in order to calculate that correctly, we must
also know the frame's CRC. Hence, the algorithm also includes CRC
calculation routine.
The correctness of the algorithm was verified on an oscilloscope for
several different SFF and EFF frames.
Currently only CAN frames are supported. For CANFD frames, a different
algorithm is needed. CANFD uses different CRC polynomials and
calculates the CRC from the staffed bit-stream (CAN calculates CRC
from de-stuffed bit-stream).

- in the long CAN frame representation use %03X/%08X instead of %3X/%8X
- introduced unified buffer size definitions for ASCII CAN frames
- updated documentation
cangen.c
- support CAN FD frames (added -f option to create CAN FD frames)
- added -m option ('mix') to create random extended / RTR / CAN FD frames
- fixed the 'fixed data' option which was zero'ing the payload by the time
