Change order of operands as gcc uses a hardcoded register per operand it seems
even for static functions
thus reducing unneeded moved (now functions try to pass the same argument in
the same spot).
Change signed int to unsigned int for array indexes as signed requires signed
extension while unsigned is free.
move the +52 up and merge it where it will end as a lea instruction, gcc always
splits the 52 out there turning the free +52 into an expensive one otherwise.
The changed code becomes a little faster.

This should be faster (couldnt meassue a difference), and its less picky
on slightly out of spec dquant.

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.

The various avcodec_thread_init() functions are updated to return
immediately after setting avctx->thread_count.  This allows -threads 0
to pass through to codecs.  It also simplifies the usage for apps
using libavcodec.

 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 option limits the CPU time used by ffmpeg to the number of seconds
specified.  After this time, the OS sends a SIGXCPU signal, which we
handle and attempt to exit cleanly.  If the process is stuck, the OS
will deliver a SIGKILL one second later, forcibly terminating the
process.

This functionality is useful in automated setups where a runaway ffmpeg
process would otherwise go undetected.
