Add xtables.c and xtables.h
In order to support the compilation of third-party utils, we encounter some
situations where the macro is not defined, refer to the common implementation
of other systems, add relevant definitions and empty function.

Socket binded to INADDR_ANY is not intended to receive unicast traffic before being fully configured, at least dhclient configured with socket-only won't do so on Linux and BSDs (https://github.com/isc-projects/dhcp/blob/v4_4_3/common/socket.c#L1201).
We can sometimes receive unicast traffic before being fully configured, it's good, but not always, so we need to set the broadcast flag under some situations.

In dns_add_nameserver, the dns_check_nameserver is comparing addresses
with addrlen = sizeof(struct sockaddr_in) for IPv4 addresses, so the
trailing sin_zero field should be 0, otherwise it may fail to figure out
same nameserver address.

The flag '-Wno-maybe-uninitialized' is not known by clang, so a
workaround substitutes it for '-Wno-uninitialized' when clang is
being used as C compiler.
Usage:
iperf -s --rpmsg <name>
iperf -c <cpu> --rpmsg <name>
Note:
RPMsg with SOCK_DGRAM (`-u`) doesn't have server mode (bind) yet, iperf
may not work in this case before rpsock is enhanced.

Usage:
iperf -s --local <path>
iperf -c <path> --local || iperf -c <whatever> --local <path>
Can combine with other options, e.g. '-u' will result in local
UDP (DGRAM).

We'll add local/rpmsg sockets later, they're mainly different in
sockaddr, we can reuse other current logic.

Argtable's builtin glossary can produce same output and we do not need
to maintain two sets of help string. Then we're easier to add more
options to iperf.

The timer is for connect timeout, but is not cancelled on connect error,
then it may be triggered after ftpc quit and cause heap-use-after-free.
