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.

5e7dfb7de1 Move COPY3_IF_LT to lavc/mathops.h 
This obscure macro is only used in motion_est.c so having it in lavc
makes more sense.  See discussion here:

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%.

be449fca79 Convert asm keyword into __asm__. 
Neither the asm() nor the __asm__() keyword is part of the C99
standard, but while GCC accepts the former in C89 syntax, it is not
accepted in C99 unless GNU extensions are turned on (with -fasm). The
latter form is accepted in any syntax as an extension (without
requiring further command-line options).

Sun Studio C99 compiler also does not accept asm() while accepting
__asm__(), albeit reporting warnings that it's not valid C99 syntax.

80a61f08d2 Remove AltiVec vector declaration compiler compatibility macros. 
The original problem was that FSF and Apple gcc used a different syntax
for vector declarations, i.e. {} vs. (). Nowadays Apple gcc versions support
the standard {} syntax and versions that support {} are available on all
relevant Mac OS X versions. Thus the greater compatibility is no longer
worth cluttering the code with macros.

0871ae1a93 Make av_fifo*_read() ignore the available amount of data. 
This is more efficient as in practice the check is redundant most of the
time. Callers which do not know if enough data is available have to check
it with av_fifo_size(). Doing the check in *read() means the caller has
no choice to skip the check when its known to be redundant.
Also the return value was never documented in a public header so
changing it should not break the API. Besides this fixes the case where
read() failed on a 100% full fifo.
