2450c450ab telnetd: at Alexander Kriegisch <Alexander@kriegisch.name> insistence 
add an option to close sessions as soon as child exits.
Maybe it should be a CONFIG option. OTOH, maybe it should be always on,
as it mimics, say, getty's behaviour.

10916c5c6b telnetd: document bug in remove_iacs. reinstate band-aid 
which was making it near-impossible to trigger.
remove memmove call which was happening at each network read,
and in 99%+ cases was not needed. Unfortunately, +50 bytes.

Yet another attempt on saner function names:

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).

c8717cd857 telnetd: move generic stuff into libbb. It will make it easy 
to make other server applets IPv6-aware too.

75f8d080a2 telnetd: we were having telnetd with is ONLY inetd or ONLY standalone.

67b23e6043 getopt_ulflags -> getopt32. 
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

099ed50f91 Unbreak allbareconfig a bit. (The telnetd.c fix is a perfect example of why 
applets which are a forest of #ifdefs are unmaintainable.)
