Modifications to VPS syntax (signal PTL for single layer OLSs)
PTL part only (HRD part to be implemented by Sharp)

Bug fix for loop filter initialization when min CU size is not 4; changed intra chroma minQT size in software to luma unit

Checking condition is substituted by helper function isLumaScalingList(). Also the constants are ZZmodified into the
exsiting macro.

Implementation of JVET-Q0468 support of min Luma coding block size, and JVET-Q0469 for Intra Chroma Min QT bug fix

Modified SAO for 12 bit coding.
Also removed SAO offset from the HEVC RExt PPS extension.
The HEVC RExt PPS extension and the associated
cross-component-prediction should be removed in the future

Bugfix of JVETQ0172 (Disallow differing chroma format and different bit depths for cross-layer prediction) and bugfix of setting inter_layer_ref_pics_present_flag and constraint (When vps_independent_layer_flag[ GeneralLayerIdx[ nuh_layer_id ] ] is equal to 1, the value of inter_layer_ref_pics_present_flag shall be equal to 0.)

Printing a warning at the beginning in case that picture sizes and the scaling window are defined that could potentially exceed the constraint

xInitScalingLists()

Slice-level switch between TS residual coding and regular residual coding for lossless coding as in JVET-Q0089.
One SPS flag that controls both luma and chroma BDPCM simultaneously as under JVET-Q0089 (meeting notes) - removed chroma BDPCM flag.
Modified the .cfg files to reflect high-level chroma BDPCM changes.
Fix: Disabled CCALF in lossless.cfg (necessary) CCALF cannot be used if ALF is disabled (disabled in lossless.cfg)
