ce7c717900 Declare the PIX_FMT_GRAY8 pixel format as a paletted format. This is
consistent with the allocation currently done for PIX_FMT_GRAY8
pictures.

No significant slow-downs have been measured.

045b60bf9b Make SHA digest function write digest value with AV_WN32 instead of assuming
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.

34e52abb62 DECLARE_ALIGNED macro for TMS470 compiler
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.

8a24e98d50 Make DECLARE_ALIGNED macros work with external array specifiers
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.

92c6a099ba H264 DXVA2 implementation
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.
