Replace most instances of ws_debug_printf() except in
epan/dissectors and dissector plugins.
Some replacements use printf(), some use ws_debug(), and
some were removed because they were dead or judged to be
temporary.
Only CAN protocol is supported. Extra information available in J1939
entries is ignored since the J1939 wireshark dissector works with
raw CAN frames and makes no use of this extra information.
The log format may also encapsulate LIN messages which are not
supported by wireshark and thus are ignored.
The only limitation is that relative timestamp format is not
supported. If a file defines relative format of timestamps, packets
are extracted, but timestamps are omitted, since random access deems
impossible without reparsing the whole file up to the packet of
interest. In order to support relative timestamps we need to parse
the whole file at once on open and either dump into a temporary
PCAP file or keep messages in a private list and provide access
to them on read()/seek_read().
The change also creates a separate header for CAN frame structure
definitions which are used by several file readers (candump and
busmaster for now).
