Please name these two files cookie_util.h and cookie_util.cc,
without the 's'.  This is the convention in src/base and
src/net.

+#define NET_BASE_COOKIE_UTILS_H_
+#pragma once
+
+#include <string>
+
+class GURL;
+
+namespace net {
+namespace cookie_utils {

[wtc, 2011/11/10 19:29:29]

Same with the namespace name: please remove the 's'.

+                               const std::string& host);

+// Determine the actual cookie domain based on the domain string passed
+// (if any) and the URL from which the cookie came.

+//   -domain cookie domain (ex: ".google.com")

Based on what I see in this CL, only DomainIsHostOnly is
worth moving out of CookieMonster.  GetEffectiveDomain and
GetCookieDomainWithString are still only used in cookie_monster.cc,
so it seems that they can remain in that .cc file.
