This patch includes: 1. Save http trailers in the header array in chunk decoder. 2. Take trailers from chunk decoder in OnStopRequest(). 3. Add serverTiming attribute in nsITimedChannel. 4. Parse server timing header when GetServerTiming() is called. --HG-- extra : rebase_source : 77c92b8a31d3d7eebb33aea266888f944af33327
