merges r32222 from trunk into ruby_1_9_2.

--
* lib/webrick/httprequest.rb (setup_forwarded_info): Parsing request 
  header failed when the request is from 2 or more Apache reverse 
  proxies. It's said that all X-Forwarded-* headers will contain more
  than one (comma-separated) value if the original request already
  contained one of these headers.  Since we could use these values as
  Host header, we choose the initial(first) value. See #4922.

* test/webrick/test_httprequest.rb (test_forwarded): Test it.
