- create own files for HRD classes
- rename HRD to HRDParameters
- create HRD class that can hold all HRD related parameters as base for encoder/decoder specific implementations

patch-by: Tobias Hinz

- includes special handling for dps ID equal to zero (JVET-N0869)
- writing of parameter set can be enabled by parameter EnableDecodingParameterSet

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

Relying on dead function

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

keep max TU in #define for possibility of keeping the parameter

TU max/min size are constants in the VVC draft. Reflecting this in the software.

Merge functionality from HM (macro JCTVC_Y0038_PARAMS). Add an additional
configuration file parameter that allows re-sending parameter sets at every
random access point.

compositeRefEnabled is an encoder only option. It should not be stored in the SPS.
This commit is the last to remove unused parameters from SPSNext. Thus also
all comments related to SPSNext are removed.

- all elements of SPSNext are moved into SPS
- syntax elements of SPS are sorted according to draft (as far as possible)
- comments were added where software and draft diverge

 - CE9.2.1g + RefinedMV only for MC and TMVP + SAD cost
