* commit '48a5adab':
  lavfi: add avfilter_init_str() to replace avfilter_init_filter().

avfilter_graph_create_filter() opaque is still passed to avfilter_init_filter()
which continues to pass it to init_opaque as its still used in the buffer sinks
the sinks should be changed and the opaque passing removed

Using the first names of authors sounds somewhat unprofessional
and might be considered offensive which is not intended.
The new names use the initials of the authors due to simplicity
and the possibility to apply it consistently without the need
to find political correct names for each future case where
alternative codecs might exist. Also its shorter ...

If someone has a better idea, like maybe 2 random letters
and people prefer it then iam happy to switch to that ...

In particular, show h value in degrees.

This also drops support for "flat syntax" and "reinit" command.

"reinit" command is not very robust and complicates the logic more than
necessary, since requires to reset all the options in the command.

*This is a syntax break*.

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.
