mbselib:
The virus stream scanner can now uses IPv4 and/or IPv6 to
connect to the clamav server and can use server clusters too.
Connect smtp, pop3 and nntp upgraded to IPv4 and IPv6 use.
mbcico:
Can accept both IPv6 and IPv4 calls.
Can call IPv4 and IPv6 nodes.
mbtask:
Upgraded the ping function to newer system calls. Note that
for now I leave the interbbs chat IPv4 only.
mblogin:
Don't use gethostbyname function.
v0.95.11 14-Jan-2011 (patches by Scott Street).
