Several log messages used format specifiers which did not match the
types of the provided arguments (e.g. %d or %i for size_t/ssize_t,
%ld for int64_t/time_t and size_t for the '.*' precision). On 64 bit
hosts (and for int64_t/time_t on 32 bit hosts) this leads to wrong
output or undefined behaviour when the log level is enabled.
Additionally the seek response position was compared to the requested
offset without le32toh() conversion which fails on big endian hosts.
Fix the format specifiers and add the missing le32toh() conversion.

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
