[FFmpeg-cvslog] Change all uses of restrict to use av_restrict instead.

[Ronald S. Bultje]

ffmpeg | branch: master | Ronald S. Bultje <rsbultje at gmail.com> | Fri Jun 15 15:52:05 2012 -0700| [17fad33f81c7e9787fcdc17934fc1eee6c6aa4bf] | committer: Michael Niedermayer

Change all uses of restrict to use av_restrict instead.

Defining restrict results - for some compilers - in changing other
uses of the restrict keyword also, e.g. __declspec(restrict) gets
changed to __declspec(__restrict) on MSVC. This causes compilation
failures. Therefore, using a private namespace macro instead is
more reliable and robust.
