- Code cleanup.

  - Incorrect clipping at picture border and insufficient picture buffer margin.

Consistently subtract one compared to old code.

JVET-O0236 Removal of a parsing dependency

Replacing num_brick_rows_minus1 with num_brick_rows_minus2

 The following fixes has been made:

   - Removed prefixes like 'i' for new variables

   - Adding braces also for if-clauses with a single statement

   - Removed some trailing spaces

   - Changed variable precedingDRAP in Picture from int to bool

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.

 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.

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

The sanitizer reports that a call to getBrickIdxBsMap() tries
to access an out-of-bounds element. The size of the array
brickIdxBsMap[] is thus increased by 1 and its last element is
initialized to some large value

initial commit of JVET_O0119_BASE_PALETTE_444: palette in HEVC and palette mode coding in JVET-N0258

removes the last remains of HEVC related code

JVET-N0805: APS for LMCS (using different APS types)

See merge request !577

implements:
- splitting tiles into bricks
- raster-scan tiles
- uniform and non-uniform splits
- all tiles/bricks in one slice
- each brick one slice
- PPS syntax

missing:
- rectangular tiles
- slice header syntax

further todo:
- rework slice mode 2 to use multiple tiles for byte size matching
- lots of renaming (tile->brick)

move m_fixedFilterNum to CommonDef.h, rename bRdo and bRedo to isRdo and isRedo, remove redundant stat derivation.

- tiles are in the VVC spec for 3 meeting cycles now
- cleanup helps with adaptation for tiles to current draft

includes:
- rename flag HandleCraAsBlaFlag to HandleCraAsCvsStartFlag
- changes of NAL unit types (reduced number)
- profile_tier_level and general_constraint_info structures

- remove duplicate ALF parameters from Slice
- add activation (to avoide overwriting when a new APS arrives)
- rename macro
