Do not leak the expressions.

This is shorter and consistent across filters.

With the introduction of AVFilterContext->is_disabled, we can simplify
the custom passthrough mode in filters.

This commit is technically a small compat break, but the timeline was
introduced very recently.

Flag added in a few simple filters. A bunch of other filters can likely
use the feature as well.

Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it
and use AVFrame instead.

Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

This allows the iteration callbacks to discover the internal class and
options, and show them when required.

This is due to the design of components iteration through AVClass
child_class_next() callback, which requires that two components cannot
share the same class.

It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.

The macro can be used to define consistently the internal class of a
filter, save some typing and factorize.

While here:
    - add missing .version and .category,
    - make .class_name consistent across filters,
    - align declarations.

They are only useful inside filters and we don't allow user filters for
now.

It is only useful inside filters and we don't allow user filters for

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.

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.
