Fixes CID732166.

The lists are sorted first by type (video first)
and then alphabetically by name.

Fix ticket #1669.

Filters now use null pointers to indicate having no input/output pads,
rather than empty lists of pads. We can't assume pad is non-null
anymore.

Fixes bug 352.

func2_arg is the same as func_arg, except it has one additional
parameter. Change all func_arg callbacks to take that parameter (and
ignore it).

Extract of the output:

| Individual channels:
| NAME        DESCRIPTION
| FL          front left
| FR          front right
| <snip>
| SDR         surround direct right
|
| Standard channel layouts:
| NAME        DECOMPOSITION
| mono        FC
| stereo      FL+FR
| <snip>
| octagonal   FL+FR+FC+BL+BR+BC+SL+SR
| downmix     DL+DR

Currently it takes a mask and value, such that options for which
(flags & mask) == value.

Change it to take required flags and forbidden flags instead. This is
shorter and simpler to understand.

Don't require every caller to supply them.

show_foo() functions are declared as void show_foo(void), but called as
int show_foo(const char*, const char*).

Make it print a list of AVCodecDescriptors.

Add new -decoders and -encoders options that print lists of decoders and
encoders respectively.

Avoid to print a pointless name of the context followed by an empty list.

The new function is called avformat_match_stream_specifier()
and does not include logging the error message.

This provides a more precise identification of the compiler used.

This is required for CommandLineToArgvW. Normally, shellapi.h is included
implicitly by windows.h, but if we define WIN32_LEAN_AND_MEAN (or some of
the other earlier headers have included windows.h with that option),
windows.h doesn't include this one.

Thus explicitly include the headers we really need, for clarity and
compatibility.

Allow to show different supported multi-threading methods for an
encoder/decoder pair.

This allows passing the right options to encoders when there's more
than one encoder for a certain codec id.

It will be used by avplay.

This reverts 78da04384a6c22820518706d84631006d31a85ea; 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.

The stream can be specified as "#129" or "#0x81".
It is especially useful for VOBs dumped from a DVD,
where the language-id mapping is available externally
and the probing can find the streams in a random order.

This fixes the warning:
cmdutils.c:897: warning: ‘type’ may be used uninitialized in this function

Also add the public interface libavfilter/buffersink.h.

This way we don't require a clearly defined corresponding input stream.

The result for the xwd test changes because rgb24 is now chosen instead

The preset files have been renamed some time ago.

Note, this doesnt break compatibility with libav, as libav
has implemented a incompatible and more limited system under the same
-cpuflags command line option we used since some time.

The differences to libav for example are we can do things like
ffmpeg -cpuflags -sse+mmx -cpuflags +3dnow
Its also possible in our system to force flags that have not been
detected as available
And our -cpuflags works with all tools not just 1

Useful for testing.

Fixes listing encoders.

This library does not fit into Libav as a whole and its code is just a
maintenance burden.  Furthermore it is now available as an external project,
which completely obviates any reason to keep it around.

This allows globally forcing specific cpuflags (or lack thereof)
Useful for debugging and benchmarking
