This reverts 78da0438; it is not
required anymore since the previous commit (these extended checks were
for the -timecode option in both muxers and encoders), and reduces the
diff with the fork.

Some demuxers set a timecode in the format or streams metadata. The
muxers now make use of this metadata instead of a duplicated private
option.

This makes possible transparent copy of the timecode when transmuxing
and transcoding.

-timecode option for MPEG1/2 codec is also renamed to -gop_timecode. The
global ffmpeg -timecode option will set it anyway so no option change
visible for the user.

avfilter_default_filter_name() is supposed to access an AVFilterContext
struct, if used with a private struct it will cause a crash since it will
access fields which are non defined in the private struct.

Helps debuggability.

The function is modelled after av_default_item_name(), and will print the
name of the instance filter if defined, otherwise the name of the filter.

This allows to show the instance name in the log, which is useful when
debugging complex filter graphs.

The test program is useful for checking which raw formats are currently
identified by a codec tag.

icodec can be NULL if there is no input stream
clearly associated with the output stream.
