pixdesc.c, which are now not anymore marked as static inline.

Fix the inclusion of the private header intreadwrite.h in the public
header pixdesc.h.

that output may be written as uint32_t since output buffer may not be aligned
(and it's silly to force alignment on it) and it does not work in that case
properly on some architectures.

system default one.

This compiler supports gcc-style alignment attributes for struct,
but not for global variables.  For the latter, alignment can be
specified with a pragma, which does not work for struct members or
local variables.  By using both pragma and attribute, one or the
other will always take effect.

Unfortunately, no means exists for aligning stack variables.

The seemingly equivalent _Pragma(AV_STRINGIFY(x)) is not accepted
by some compilers.

The macro implementation might need the name of the variable being
declared for compiler-specific syntax.  Moving array specifiers outside
the macro invocation allows this to work.

It allows VLD H264 decoding using DXVA2 (GPU assisted decoding API under
VISTA and Windows 7).
 It is implemented by using AVHWAccel API. It has been tested successfully
for some time in VLC using an nvidia card on Windows 7.

 To compile it, you need to have the system header dxva2api.h (either from
microsoft or using http://downloads.videolan.org/pub/videolan/testing/contrib/dxva2api.h)
 The generated libavcodec.dll does not depend directly on any new lib as
the necessary objects are given by the application using FFmpeg.

This obscure macro is only used in motion_est.c so having it in lavc
makes more sense.  See discussion here:
