JVET-O0594: BDOF reference sample padding using the nearest integer sample position

See merge request !727

JVET_O0594/O0252/O0506/O0615/O0624: BDOF reference sample padding using nearest integer sample positions

JVET-O1168: cu chroma QP offset

JVET-O0193/O0375: remove transform depth in cbf ctx

See merge request !724

remove INCLUDE_ISP_CFG_FLAG macro (leftover from last meeting cycle)

See merge request !725

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.

JVET-O0163/JVET-O0588: Remove switching between L0 and L1 for temporal MV

See merge request !697

1. moving the cbf signaling from transform_tree() to transform_unit()
2. using transform depth 1 for coding chroma cbfs for CUs with SBT; solving the s/w bug reported in ticket #338
