This avoids potential undefined behavior in debug mode while still allowing
developers which want to check for potential additional overflows to do so
by manually enabling this.

Add dxva2_pool_release_dummy() and use it in call to
av_buffer_create() in dxva2_pool_alloc().
Prior to this change, av_buffer_create() was called with NULL for the
third argument, which indicates that av_buffer_default_free() should
be used to free the buffer's data. Eventually, it gets to
buffer_pool_free() and calls buf->free() on a surface object (which is
av_buffer_default_free()).
This can result in a crash when the debug version of the C-runtime is
used on Windows. While it doesn't appear to result in a crash when
the release version of the C-runtime is used on Windows, it likely
results in memory corruption, since av_free() is being called on
memory that was allocated using
IDirectXVideoAccelerationService::CreateSurface().

This way, Doxygen is happier as aliases are now grouped together, and
it never handled #define's in an enum well in the first place.
Y400A already exists as an enum assignment.
Including this header in a C++11 program (inside extern "C") will
throw an error because it looks like a user-defined literal. Add a
space between the two tokens to avoid the problem.
memalign() is not guranteed to be compatible with free() or realloc()
and for platforms in this category we have --enable-memalign-hack
(which should be enabled automatically if such system is detected)
Trying to somehow half support systems that can free() memalign memory
but not reallocate it seems not worth the amount of work needed to
keep 2 then incompatible allocation systems and ensure their
seperation. That is unless this would affect a major platform
on which we want to avoid the memalign hack code
The warnings also cause wasted time and effort as people try
to maintain a separation that does not exist currently.
