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

This reverts commit 8e16ada0.

Use vectors and resize them if needed instead of deleting and
reallocating memory for every picture. This appears to have a
significant impact on decoder run time.

Use PLTRunMode type where appropriate instead of bool since
using vector<bool> creates a number of issues

fix CHECK on cu mode, considering palette mode

Adopt JVET-O0070 method 4-2.1a

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

Software implementation for N0278:
1. Added VPS encoding in encoder
2. Add new project StreamMergeApp to N-to-1 bitstream merge
3. Changed decoder to support only decoding the specified layer stream

Nan Hu authored 5 years ago and Karsten Suehring committed 5 years ago

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

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

There is a conflict with JVET_M0427_INLOOP_RESHAPER that is triggering a debug assertion that checks that the width is not 1.
