Log Message:
Update squid package to squid-2.5.4nb3.
Apply two offcial patches.

* FQDN lookups sometimes returns garbage

	synopsis	FQDN lookups sometimes give garbage after the result.
			This can be seen as junk in access.log when using
			log_fqdn or false access control results when using
			dstdomain acl type and the user requests a URL by IP
			address.
	severity	Minor
	date		2003-12-04 10:04
	bugzilla	#846, #834, #433
	versions	Squid-2.5 and earlier
	platforms	All
	workaround	Don't use log_fqdn or alternatively compile Squid with
			--disable-internal-dns

* Cleanup of connect & dns timeouts etc

	synopsis	Several minor errors related to how Squid finds a
			connection where to forward requests. This patch

			o Adds a new configuration parameter "forward_timeout"
			  to control how long Squid tries to find a method to
			  find a path where to forward the request before
			  giving up.  Defaults to 2 minutes.
			o The default connect_timeout tuned down from 2 minutes
			  to 1 minute to allow for two attempts to find a
			  suitable path within the forward_timeout
			o fqdncache/ipcache restructured to allow for DNS code
			  to allow the queried name to be logged in cache.log
			  on errors.
			o negative_dns_ttl now overloaded to also specify the
			  minimum ttl used when caching DNS responses, and
			  tuned down from 5 minutes to 1 minute.
			o default dns_timeout tuned down from 5 minutes to
			  2 minutes
			o some minor compilation warnings on
			  --disable-internal-dns corrected
			o properly report DNS timeouts as timeouts and not just
			  "No DNS records"
