Ignore LL-HLS requests for segments that have already expired

[HyeockJinKim]

If an LL-HLS request comes in for a segment that has already expired, it will always wait until the session is terminated.
If the segment is already in an inaccessible state, it is handled so that it does not wait any longer.

Can I get a review? @aler9

Hello, this seems ok to me, fix the lint errors and the patch will get merged.

Tests are ok, although i usually write them by using public methods only ("black box approach") in order to assess the visibility of the tested feature from the outside and also to avoid to directly use private members or methods, since these can change over time. Therefore, instead of mockSegmentMP4 i would have used WriteH26x() multiple times in order to generate those mock segments. But this is just a detail, not mandatory in any way.

I fixed lint error in testcode.
