JVET-O0236 Removal of a parsing dependency

  - Add macro for code changes.

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.

Implement option B for NAL unit header syntax.
NOTE: Neither the JVET-O0129-v2 or the JVET-O2001-vEJVET-O2001-vE documents specify a nal unit type NAL_UNIT_VPS, and this nal unit type is required. In this implementation NAL_UNIT_VPS is defined to be 25.

 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.

- CVS to start with GDR

- 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

Not sure how this got here. Was it added after automated
macro removal?

If we don't even store the VPS at the decoder, at least properly delete it.

Macro: JVET_O0414_SMVD_LTRP

  - Initialize some weighted prediction and slice address variables in case they are not set during slice header parsing.
