[x264-devel] Windows x64 support

[BugMaster]

I think I finished patch (in some places it is not very optimal or
looks unpleasant, but this I think you can fix).
Here is patch:
http://stashbox.org/328941/x264_win64_support.01.r1057.diff
And here is other stuff maid during patching:
http://stashbox.org/328939/misc.rar
It contains project files for MSVC 2008 for compiling Win64 builds and
modified pthreads library (sources and binaries) for Win64 (based on
current CVS trunk).
