[Clément Bœsch]

ffmpeg | branch: release/1.2 | Clément Bœsch <u at pkh.me> | Sun Sep  8 16:17:46 2013 +0200| [a0779a2ee504e9f38cab91296ba96fa189804f9b] | committer: Alexander Strasser

avformat/srtdec: skip initial random line breaks.

I found a bunch of (recent) SRT files in the wild with 3 to 10 line
breaks at the beginning.

(cherry picked from commit cfcd55db164e0acc0c30b2cf084e6eebe9741d34)
