Fix for issue #3450: serf will call handle_response multiple times for the same response if that response is not completely received. 
Fix for issue #3450: serf will call handle_response multiple
times for the same response if that response is not completely
received. 

This patch ensures that svn tries to handle authentication 
only when the complete response is received, so that
it's only done once.

* subversion/libsvn_ra_serf/util.c
  (handle_response): don't handle the authentication request
   until the complete response (which is discarded) is
   received.
