9106107a50 Make unix (local) sockets work without IPv6 enabled
The xsocket_type() function had an optional "family" argument
that was enabled only if IPv6 is enabled. In the case of the
function was called with a valid AF_UNIX argument, and IPv6 is
disabled, this argument was silently ignored.

This patch makes the "family" argument mandatory, while keeping
the old behavior i.e., if AF_UNSPEC is passed, we try first IPv6
(if it's enabled) and fallback to IPv4.

Also I changed all callers of xsocket_type() to reflect its new
interface.

0ef64bdb40 *: make GNU licensing statement forms more regular
This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).

b9a279ba94 Unify ping and ping6. ping has -4 and -6 which force
name resolution into IP or IPv6 only, otherwise
we take address family returned by host2sockaddr()
in lsa->sa.sa_family. IOW: "ping ::1" with do IPv6 ping,
"ping 127.0.0.1" will do IPv4 ping.
ping6 is aliased to "ping -6".

prototypes (heresy!), add spaces in places like "flags&NETSTAT_CONNECTED",
removed unused #defines, #ifdef -> #if, use uint32_t for ipv4 addrs.

9de420c27c Improve generic ipv4+ipv6 support in libbb.
Convert telnet to it. Now this works:
telnetd -b [::1]:1234 - bind to IPv6 non-standard port
telnet [::1]:1234 - connect to IPv6 non-standard port
telnet ::1 1234 - same
This does not require ANY ipv6-specific code in applets
(no struct sockaddr_in6. In fact, no sockaddr_in, too).
