Accordint to the new UAPI version, bind() with PGN set, should not be used

Currently if we send lots of bytes, test1939 output will get unreadable.
Make it easier to read by splitting output dump.
New format will looks as following example:
root@DistroKit:~ testj1939 can0:0x90 -r
80 12300: 01 23 45 67 89 ab cd ef

Currently if we set size which is more then 128 byte
will silently ignore provided value and send only maximal
supported size.
