- This merge request provides the implementation for JVET_O0299, i.e., Support for user defined Scaling List Matrics in the APS.

 Added back sps_temporal_mvp_enabled_flag to align with specification text in JVET-O2001-vE. \n This also means that sps_sbtmvp_enabled_flag can be signaled in SPS as before instead of in PPS.

- create ceilLog2() function based on floorLog2
- use intrinsics for MSVC in floorLog2
- replace all ceil(log2()) calls in HLS with ceilLog2()

Implementation for JVET_N0100, proposal 1, allow signaling information about long-term reference picture POC LSB in reference picture list syntax structure.

Add compliance checks for:
sps_log2_diff_max_bt_min_qt_intra_slice_luma
sps_log2_diff_max_tt_min_qt_intra_slice_luma
sps_log2_diff_max_bt_min_qt_inter_slice
sps_log2_diff_max_tt_min_qt_inter_slice
