@OrenMe This PR together with #5264, in Tizen 3.0 with a HLS playlist of 8000 segments, the parsing time goes from 250ms to 70ms. It is a great improvement.

@avelad this is amazing, thanks for that!
For live playback on that version each time we get a live ma first refresh for a long dvr window stream we see GC goes crazy.
We tested the previous PR and so small change but we will now test with this one as well.
When is this due? We are waiting for both in 4.4.0

Related to #5261

This PR delays the creation of the final urls of the segments so that
they are not calculated in each media playlist parsing.
