Deprecate and mark for deletion the function guess_stream_format(),

and clone its code to ffserver_guess_format() in ffserver.c.

guess_stream_format() is hackish since it relies on some undocumented
properties of the name of the muxers (wich is currently only relevant
for the ASF muxer), and has no use outside ffserver.c.
