* using MOVQ_WONE/MOVQ_BFE as two instruction instead of static memory value access
as its always faster
* PAVGB_MMX macro is using now mm6 -> mm7 is unmodified
* replaced original pixels_xy2_mmx with new faster and equal implementation
* replaced usage of mm7 for other then ZERO contstant in _rnd & _avg file with mm6

* Change to dynamically allocated buffers. Should reduce memory footprint significantly
as well as eliminate a call to av_abort!
* Better version of WMP rate switching infrastructure. Currently turned off till
the PTS fixes are in.
* Added a Redirect type feature. This allows URLs served by ffserver to just
redirect to somewhere else. You might want to do this. Really this needs to
be enhanced -- say to handle all 404 pages.
* Add mechanism to automatically fire up ffmpeg on ffserver start. This is turned
on by adding the Launch keyword to the <feed> definition.
* Add logic to take care of non-wmp user agents requesting .asf files. They now get
a [reference] file with an appropriate mime type. This fixes the mplayer problem.
* Make sure that we have a large buffer for the stats page.
* Add a FaviconURL keyword to the status stream definition. If set, then it
generates the appropriate HTML so that IE and Mozilla will display the favicon
as appropriate. OK -- this is a pretty random feature.
* If the ffmpeg is running as a child of ffserver, then report it's CPU usage
on the status page. [This is linux only -- maybe somebody could do the work for
another OS. The tricky thing is getting the 'ps' command right.]

returns EOF -- e.g. it is connected to /dev/null
* Make the 1MB video buffer only allocated once rather than on each frame.
The allocation and deallocation causes significant performance loss as the
kernel remaps the address space each time.

as its functionality is used even in those parts which are being
compiled without this flag

requests. The current state is that at startup, WMP will get the
best stream that it can handle. However, subsequent rate switching
only puts a message in the log saying what the new stream ought to
be. Solving this will be tricky. I guess that we would have to wait for
key frames to appear in the new stream, and then switch over to it.
Some care would be needed to deal with the PTS of the new stream
versus the old stream.
