JVET-N0741: Enable Rate Control with In-Loop Reshaping

See merge request !506

Fix the huge loss in rate control with the macro WCG_EXT enabled by In-Loop Reshaping by saving the unadjusted lambda for RD cost before encoding current CTU.
This commit has removed the macro as recommended.

- 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

JVET-N0349: decoding parameter set (DPS)

See merge request !551

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

Fix ticket #263 on invalid IBC block vector

See merge request !548

Xiang Li authored 5 years ago and Karsten Suehring committed 5 years ago

Fixed the encoder bug which leads to incorrect BVd signaling. The incorrect BVd triggers exception on valid BV checking.

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)
