The default static buffer sizes are too small to handle the 8 entries returned

The default static buffer sizes are too small to handle the 8 entries returned
by 'nslookup www.yahoo.com' and 'nslookup mail.hotmail.com', and thus we
currently return ERANGE when trying to lookup some of the most popular hosts on
the planet.  Whether these sites deserve to be popular is a question I'll leave
for someone else to worry about.

This change makes certain we have enough static buffer space to handle about 21
IPv4 IP address replies per DNS query.  Far more than enough to handle common
cases such as www.yahoo.com and mail.hotmail.com.
