JVET-O0236 Removal of a parsing dependency

Replacing num_brick_rows_minus1 with num_brick_rows_minus2

  - Add macro for code changes.

The fix was confirmed as part of the specification.

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.

When no RPL are parsed, RPL0, RPL1 and NumRefIdx shall be reset in the slice, else the decoder crash in checkCRA function

- 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.
