As Hakan Engblom pointed out a CAN 2.0B RTR frame can contain a non-zero DLC
value which was not addressed by parse_canframe() and sprint_canframe().
This patch adds support for non-zero DLC values in a way that legacy logfiles
are still usable as the DLC can optionally be added.

A configured inverse filter e.g.
cangw -A -s can0 -d can1 -e -f 123~7FF
has been displayed with 'cangw -L' like this:
cangw -A -s can0 -d can1 -e -f 20000123:7FF # 0 handled 0 dropped 0 deleted
While 0x20000000 was the value of CAN_INV_FILTER.
This patch fixes the output to the expected display:
cangw -A -s can0 -d can1 -e -f 123~7FF # 0 handled 0 dropped 0 deleted

Added new option '-i' for can-gw rules to allow to route CAN frames back to the
originating/incoming CAN interface (which is disabled by default).
CAN frames that are deleted due to the violation of the max_hops limit are now
printed when displaying the configured rules with 'cangw -L'.

nbytes is used after writing the CAN frame to check for an additional command
in the string buffer. Therefore using nbytes while writing the CAN frame is
wrong. Replace it with 'tmp' which can be used here without problems.

This is a major upgrade of the basic tools to handle CAN FD frames.
The library to parse and print CAN frames and logfiles has been extended.
In detail:
asc2log.c | 5 +
candump.c | 24 ++++---
cangen.c | 172 +++++++++++++++++++++++++++++++++------------------
canlogserver.c | 28 +++++---
canplayer.c | 25 ++++---
cansend.c | 55 ++++++++++++----
lib.c | 189 ++++++++++++++++++++++++++++++++++++++-------------------
lib.h | 109 ++++++++++++++++++++++++--------
log2asc.c | 8 +-
log2long.c | 26 ++++++-
10 files changed, 440 insertions(+), 201 deletions(-)
asc2log.c / log2asc.c
- updates for new lib functions
- still can only handle CAN2.0 frames (no new info about ASC file layout)
log2long.c / canlogserver.c / canplayer.c
- updates for new lib functions to handle CAN FD
lib.h / lib.c
- reworked lib functions to handle CAN FD
- parse_canframe() now returns CAN_MTU and CANFD_MTU on success, 0 at failure
- added can_dlc2len() and can_len2dlc() helpers
- moved hexstring2candata to hexstring2data to support simple byte buffers
- 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
- updated help text
candump.c
- support CAN FD frames (print, bridge, log)
- distinguish frame types by length info: [0] = CAN2.0 [00] = CAN FD frame

Prior to this commit, do_get_nl_link assumed there would only be a single
reply for a dump request. On my system with multiple can interfaces, this
would cause only half of them to be listed in the dump reply. This change
checks for NLMSG_DONE dump terminator and stops receiving messages once
received.

This way a user can specify a gap below 1ms. This is somehwat similar
to setting the gap to 0, but the ENOBUFS are greatly reduced, so a given
amount of CAN messages by -n is still usefull and useable.

When using libsocketcan on git://git.pengutronix.de/git/tools/libsocketcan.git,
I kind of missed a method to fetch the can device statistics.
This patch adds that functionality.
I think this is the proper library to put such function.
