Implementation of the Dependent RAP indication SEI message. Pictures are marked as DRAP pictures using the encoder config parameter DRAPPeriod, which sets DRAP pictures periodically. Conformance checks are performed at the decoder side to verify that the DRAP pictures follow the constraints in the VVC specification.

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.

Simplify code and rename variables to conform to guidelines.
Code simplification should result in fewer calls to
CodingStructure::getCURestricted().

- 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 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.

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

- add option to completely disable
- add iparameter to software manual

  - Remove additional unused variable.
