Build the CAN frame ASCII output inside a single (big) buffer as
preparation for CAN XL support.
This unifies different output modes (fprintf/sprintf/printf) at
the time of the CAN frame text generation.

Replace maxdlen parameter and use CANFD_FDF flags instead.
Since the CANFD_FDF flag has been introduced in can.h the struct canfd_frame
can be used for CAN CC and CAN FD frames as a dual-use data structure.
Remove the extra maxdlen parameter in library calls and only use the
CANFD_FDF flag to differentiate the two CAN CC/FD frames.

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

Use the correct flag MSG_CONFIRM to detect frames generated on this
socket.
Fixes: c35ed80b3d ("canfdtest: use struct msghdr::msg_flags to detect own frames")
