The current way to know if an entry in reference picture array is free is to test if PoC = UNUSED_REF. Since UNUSED_REF is defined as '-1' that could lead to decode issue if one PoC also equal '-1'. PoC with value = '-1' exists in conformance test SLIST_B_Sony_9. Change the way unused entries are managed in reference pictures array to avoid using PoC to detect then. This patch doesn't change fluster HEVC score.
