Summary: Fixes for libwrap

Initial Comment:
When compiled with tcp_wrappers support, net-snmp
5.0.pre3 doesn't work. The wrong argument was passed to
hosts_ctl(), and no checking was done to see if the
request was coming from a network family that
tcp_wrappers supports (namely, TCP/IP[v6], UDP/IP[v6]).
The patches included here fix both of those problems,
and also accomodate the address formatting routines in
snmpTCPIPv6Domain.c and snmpUDPIPv6Domain.c to conform
to what appears to be the standard. While i was at it,
i changed the cached addresses to really be the
addresses and not the (nearly) entire socket
information. To me, it doesn't make sense to key off of
source port and network family.

One possible problem with the patch is that i don't
know exactly what a non-IPv6-enabled tcp_wrappers would
do with an IPv6 address. Probably just reject it, and
one would have to be foolish to use a non-IPv6-enabled
tcp_wrappers on a network where one expects queries
from IPv6 addresses. I mention the problem for
completeness. :)

As for testing. The best i can say is that it seems to
work for me. I don't have net-snmp completely working
yet anyway (but i hope that's just a configuration
problem), so more thorough testing is impossible for me
at the moment.

(Lastly, sorry if i do a crummy job generating patches.
I'm really new to that aspect.)
