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

Jonathan Taquet authored 5 years ago and Karsten Suehring committed 5 years ago

includes offline discussed replacement of tb(v) by ue(v) coding for alf_chroma_num_alt_filters_minus1

Note: in VVC draft 6 "–	If intra_bdpcm_flag[ ][ ] is equal to 1, ctxInc is set equal to 1.", which was set equal to 4 in VTM5. This integration also implements this change, to align cbf ctx with VVC draft 6.
