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.

It is an exact duplicate of memsetw() in h263.c.

It is used by both encoders and decoders and should not be below

It is just a logical OR of several decoder definitions, all of which depend on
CONFIG_H263_DECODER. So it can just be replaced by the latter.
