Introduce the ISOBUS File Server (FS) interface, compatible with ISO
11783-13. The implementation utilizes the kernel's existing CAN J1939
socket support.
For testing following setup can be used:
ip link add type vcan
ip l s dev vcan0 up
j1939acd -r 64-95 -c /tmp/1122334455667788.jacd 1122334455667788 vcan0 &
j1939acd -r 96-127 -c /tmp/1122334455667789.jacd 1122334455667789 vcan0 &
sleep 1
isobusfs-srv -i vcan0 -n 1122334455667788 -v vol1:/path/to/export/
isobusfs-cli -i vcan0 -n 0x1122334455667789 -m 0x1122334455667788 -I
Interactive mode currently support following commands:
exit - exit interactive mode
quit - exit interactive mode
help - show this help
dmesg - show log buffer
selftest - run selftest
ls - list directory
ll - list directory with long listing format
cd - change directory
pwd - print name of current/working directory
get - get file

As the tx_dl and flags struct elements are not relevant for listen-only
sockets, simplify the CAN FD command line option switch.

When sniffing CAN FD isotp traffic both listen-only sockets have to be
switched to process CAN FD frames.

If j1939spy is started with the verbose option "-v" or "--verbose", it
will print the error "j1939spy: listening: Success" and exit. Remove
this option altogether.

We don't need to block any signals, so a select() is sufficient. This
also fixes the problem that sigmask is uninitialized and may block the
sig ARLM, which make canbusload hang until a CAN frame is recieved.

If CAN_ERR_CNT is set, the snprintf_can_error_frame() bails out, as it
cannot decode CAN_ERR_CNT.

In 913311fc15 ("can-calc-bit-timing: add support to decode user
supplied bit timing parameters") support to decide user supplied bit
timing parameters was added. However, it was forgotten to add --tq to
the help text.
Add help text for the --tq paramter.

Commit 0be066bee6 ("cansequence: main(): allow to bind on "any"
interface") converted from SIOCGIFINDEX ioctl() to if_nametoindex()
and adjusted the error message, but forgot the "()" after the function
name, which is used in the rest of the error messages in this file.
Add the missing "()".
Fixes: 0be066bee6 ("cansequence: main(): allow to bind on "any" interface")
In commit 9567230494 ("cansequence: print out dropped packages by
socket counter"), the read() syscall was replaced by recvmsg(). Adjust
error message accordingly.
