This is mostly automated global search and replace

The deprecated aconvert filter is disabled, if it still has users
it should be updated

Samplerate and channel layouts must be set in query_formats.

They are auto-negotiated.

Also reorder some other #include when applicable.

A number of compilers, for example those from TI and IBM, choke on
these initialisers.  The current style is also quite ugly.

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

This reduces from 3 to 2 messages for the same syntax error in ffprobe,
and from 4 to 3 in filters.

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.

It will allow adding new fields to it without ABI breaks.

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.

    Add asrc_anullsrc - null audio source.

avfilter.h is a public header and the unexported audio.h header contains
only internal prototypes.

It makes more sense for a bit mask to use an unsigned type.
The change should be source and binary compatible on all
supported systems, hence micro version bump.

Fixes a few invalid shifts.

GCC 4.6.2 at least still seems to fail to put them in .rodata though,

More locally and globally consistent.

That was clumsy and confusing, only show the descriptive channel
layout string.

This is mainly useful for filters (like the sox synth), which
overwrite the content of the passed data.

The new syntax is more extensible and more user-friendly.

This breaks the previous syntax, should not be an issue as possibly
no-one is already using anullsrc.

Done to keep ABI compatible. Otherwise this is just silly

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

This also allows to remove a linking dependency of libavfilter on
libavcodec.
