[FFmpeg-cvslog] avutil: add av_fopen_utf8()

[Michael Niedermayer]

ffmpeg | branch: master | Michael Niedermayer <michaelni at gmx.at> | Fri Nov  1 01:51:14 2013 +0100| [85cabf1ca98fcc502fcf5b8d6bfb6d8061c2caef] | committer: Michael Niedermayer

avutil: add av_fopen_utf8()

fopen() on windows uses UTF-16, we use UTF-8 everywhere, this
function bridges the gap by using avpriv_open()
