The register function now specifies that the user callback should
leave things in the same state that it found them on failure but
that failure to destroy is ignored by the library.  The register
function is now explicit about its behavior on failure
(it unregisters the previous callback and destroys all mutex).

This function provides an explicit VDPAU device and VDPAU driver to
libavcodec, so that the application is relieved from codec specifics
and VdpDevice life cycle management.

A stub flags parameter is added for future extension. For instance, it
could be used to ignore codec level capabilities (if someone feels
dangerous).

This is necessary to recreate the decoder with the correct parameters,
as not all codecs invoke get_format() in this case.

Using the not so new init and uninit callbacks, avcodec can now take
care of creating and destroying the VDPAU decoder instance.

The application is still responsible for creating the VDPAU device
and allocating video surfaces - this is necessary to keep video
surfaces on the GPU all the way to the output. But the application
will no longer needs to care about any codec-specific aspects.

If a seek is requested before the decoding start there is no
current picture.

This allows the application to fall back on another hwaccel or,
more likely, software decoding.

This is actually defined in the A/52 specification.

Some encoders already use this value even
though it's reserved in the A/52 specification.

This is more portable and avoids warnings with compilers that do not
properly support av_unused.

This avoids an unused variable warning with hardcoded tables.

This avoids a trillion warnings from MSVC.

This reduces inter-library dependencies.

These are the only WMA bits shared with binkaudio. Splitting them off
reduces the binnkaudio dependency on general WMA code.

These function pointers already existed in the ARM code. Adding them globally
allows calls to the function pointers to access arch-optimized versions of the
functions transparently.

The HAVE_ prefix is reserved for macros set by configure.

Only set a value if _WIN32_WINNT is undefined or smaller than 0x0600. This is
cleaner than unconditional definition and avoids a number of redefinition
warnings. Also only define a value in one of the two dxva2 headers.

This avoids related incompatible pointer type warnings.
