Fixes CID732166.

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).

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.

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.

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

Also add the public interface libavfilter/buffersink.h.

Based on a commit by Stefano Sabatini.

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
of bgra.

The preset files have been renamed some time ago.

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.

The sample aspect ratio is a per-frame property, so it makes sense to
define it in AVFrame rather than in the codec/stream context.
Simplify application-level sample aspect ratio information extraction,
and allow further simplifications.

This fixes build errors in some environments.

This symbol name clashes with a symbol in gnutls, if linking
statically to that library.
