[FFmpeg-cvslog] extend log line buffer sizes

[Wolfram Gloger]

ffmpeg | branch: master | Wolfram Gloger <wmglo at dent.med.uni-muenchen.de> | Fri Jun 22 18:15:09 2012 +0200| [258dfff8394d383beaa639d19912b3f068f67e16] | committer: Michael Niedermayer

extend log line buffer sizes

The string passed to av_vlog() from libx264's X264_log overflows the 512
byte part_size, truncating x264 parameter output.  Double this size
and put it in a #define so it only needs to be changed in one place.
