When calling pcPicCurr->finalInit() pointers to LMCS APS or Scalining List APS
can be zero. Dereferencing those is undefined. It's also not necessary, because
the arguments passed as reference are later converted to pointers again.

Move chroma qp offset from PPS extension to PPS

- rpls_poc_lsb_lt shall be parsed when !ltrp_in_slice_header_flag
- When ltrp_in_slice_header_flag = 0, the value of st_ref_pic_flag are
needed to parse slice_poc_lsb_lt. Add the update RefPicIdentifier in
this case.
- Using two separate index ii and j might cause the overwriting of short term
information by long term one as the RefPicIdentifier array are common.
Remove j.

read/write slice sao and alf syntax, dep_quant_enabled_flag, sign_data_hiding_enabled_flag before deblocking_filter_override_flag

read/write mvd_l1_zero_flag, cabac_init_flag, collocated_from_l0_flag and WP table after slice_temporal_mvp_enabled_flag

read/write num_ref_idx_active_override_flag, num_ref_idx_l0_active_minus1 and num_ref_idx_l1_active_minus1 after delta_poc_msb_cycle_lt

Replaces 2-dimensional arrays for storing reference samples in
intra prediction with two 1-dimensional arrays. This reduces memory
usage for these buffers from 792KB to 6KB.

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

Remove unused parameters and remove default parameter values

 Added back the TMVPModeId config parameter. \n m_PPSTemporalMVPEnabledIdc is now set based on both TMVPModeId and PPSorSliceMode.

 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.

This reverts commit 8e16ada0.
