were changed to fputs to stderr).
Fix memory leak when doing axfr's.
Improvements to host program; most options and types fully supported.
Add (currently non-functional) -C option to host to check all SOA's
on authorative servers.  (Will require some notable changes to dighost.c
to make this a functional option.)

Issues stil needing resolution:
	IPv6 queries are not currently sent.
	Memory leak on ^C while waiting for UDP recv or TCP connect.
	A few more dig options need supporting.
	Support IXFR under dig (and maybe host).
	Support signatures (TSIG) under dig (and maybe host).
