Artem Smorodin 0a108a37e1 avformat/hlsenc: limit segments count to search duplicated segments filenames ...

This linear search has a complexity of O(n). When ffmpeg attempts to parse a playlist containing approximately 100,000 segments, it effectively causes a hang for several minutes.

This patch limits the allowed size for duplicate searches to a reasonable value. Now it takes between 0.5 and a few seconds (tested on different devices) instead of several minutes.
