These macros are redundant.  All uses are replaced with the generic

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.

63826ceb32 intreadwrite: ensure arch-specific versions are always used if defined 
The per-arch headers can define any combination of B/L/N variants.
This ensures that whatever is defined in an arch header gets used
for all equivalents not defined there.  E.g. on a little-endian
machine, AV_RN and AV_RL should give the same code.

9f5ff83f2a PPC asm for AV_RL*() 
PPC is normally big endian but has special little endian load/store
instructions.  Using these avoids a separate byteswap.  This makes the
vorbis decoder about 5% faster.  Not much else uses little-endian
read/write extensively.

GCC generates horrible PPC code for the default AV_[RW]B64 (which uses
a packed struct), so we override it with a plain pointer cast.

3c55ce039d ARM asm for AV_RN*() 
ARMv6 and later support unaligned loads and stores for single
word/halfword but not double/multiple.  GCC is ignorant of this and
will always use bytewise accesses for unaligned data.  Casting to an
int32_t pointer is dangerous since a load/store double or multiple
instruction might be used (this happens with some code in FFmpeg).
Implementing the AV_[RW]* macros with inline asm using only supported
instructions gives fast and safe unaligned accesses.  ARM RVCT does
the right thing with generic code.

This gives an overall speedup of up to 10%.
