It will be useful outside of avprobe.

The separators were changed from ',' to '|' in all the filters.

Removes an arbitrary hardcoded limit on the number of filters.

The caller needs to know what valid indices can be passed to
avfilter_pad_get_name/type.

This will be useful in avtools in the following commits.
Any other caller might also want to know this information.

Drop the unused opaque parameter from its signature.

It will be useful in the following commits.

Since this function adds a standalone filter to a filter graph and we do
not support creating such filters, there is no reason for this function
to exist.

Since we do not support "standalone" filters not attached to an
AVFilterGraph, we should not have a public function to create such
filters. In addition that function is horribly named, the action it does
cannot be possibly described as "opening" a filter.

We do not support using filters without AVFilterGraph in practice
anyway, so there is no point in pretending we do.

lavfi should never modify the filter through that pointer.

It is only used for error resilience. This allows building the
h264 decoder without dsputil, if error resilience is disabled.

The non-intra-pcm branch in hl_decode_mb (simple, 8bpp) goes from 700
to 672 cycles, and the complete loop of decode_mb_cabac and hl_decode_mb
(in the decode_slice loop) goes from 1759 to 1733 cycles on the clip
tested (cathedral), i.e. almost 30 cycles per mb faster.

Put a copy of the 8bit functions only in dsputil, where they are
used for some other things (e.g. mpeg4qpel, mspel, cavsqpel).
