* Print the performance stats every five frames, and reset

the counters, so it's not the average for the entire
   decoding time, but for the last five frames. This gives
   a more accurate picture of what's going on.
 * Added NOTE about possibly removing the SWS version of the
   colorspace conversion code unless it's used for otherwise
   unsupported conversions. David's code is about 40% faster
   in my tests (nice job!).
 * Free the sws context in NegotiateVideoFormat, if necessary.
