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

use m_pcEncCfg->getUseAffineAmvrEncOpt() to control the effect of m_pcEncCfg->getIntraPeriod() != ( uint32_t ) -1, i.e., low delay setting.

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

- Previous name: Reduced Secondary Transform (RST)
- The parameter, LFNST, should be added in cfg file for enabing LFNST, i.e. LFNST = 1

- Harmonize coefficient group sizes of chroma TBs to those used in luma TBs
- For 2x4/4x2 chroma TBs, retain 2x2 CG size.

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

Obsolete code relying on dead code like g_aiT64 array.

Use a single array with elements that comprise scan x position, y
position, and index into block instead of separate arrays.

Simplify array initialization code
