Reland r91815, "Clean up RegisterProtocolFactory calls."

It had broken the mac canaries with the warning:
cc1plus: warnings being treated as errors
/b/build/slave/Webkit_Mac10_5__dbg__2_/build/src/webkit/appcache/appcache_update_job_unittest.cc:556:
warning: 'appcache::AppCacheUpdateJobTest' has a field
'appcache::AppCacheUpdateJobTest::io_thread_' whose type uses the anonymous
namespace

This is the old gcc bug. I think the problem is Mac 10.5 vs 10.6. I'm working around by removing the anonymous namespace.
