JVET-Q0630: Parsing dependency fix for subpicture level info SEI

See merge request jvet/VVCSoftware_VTM!1474

Fix #978: HRD

See merge request jvet/VVCSoftware_VTM!1471

JVET-Q0399: Allow inference of scaling window from conformance window

See merge request jvet/VVCSoftware_VTM!1472

Note: The encoder automatically sets scaling and conformance windows and signalls them without specific config parameters. Thus also no config file option was added for the inference.

JVET-Q0237: STSA with TID Zero in Dependent Layer

See merge request jvet/VVCSoftware_VTM!1468

JVET-Q0219: Signal separate set of alternative buffering delay parameters

JVET-Q0218 (Proposal 3): Fix missing inference rule for single_slice_per_subpic_flag

See merge request jvet/VVCSoftware_VTM!1465

JVET-Q0257: Constraint expression to limit actual scaling ratios rather than the picture sizes

See merge request jvet/VVCSoftware_VTM!1463

Check that VPS is available in bitstream before accessing VPS
information in DecLib::checkSEIInAccessUnit

Encoder bug fix for HRD, whereby the CPB removal delay delta indexes for
temporal sublayers are disabled for the last GOP of the picture if it is
not a full GOP

JVET-Q0751: Constraints and properties of mixed nal unit types

See merge request jvet/VVCSoftware_VTM!1462

JVET-Q0218 Proposal1 : conditionally signal tile_idx_delta_present_flag in slice signalling

JVET-Q0346 aspect 2: scaling list used in sh

See merge request jvet/VVCSoftware_VTM!1457

JVET-Q0222: Modifications to subpicture information signalling

See merge request jvet/VVCSoftware_VTM!1455

JVET-O0397: Subpicture extraction process

See merge request jvet/VVCSoftware_VTM!1470

Functional stage: allows extraction of subpicture bitstreams that can be decoded. This includes:
- rewriting of tile structure
- rewriting of slice structure
- rewriting of picture dimensions

HRD related parts are not included yet

Update cfg files to support the parameter name change

Fix Ticket #924: Add encoder configuration checks for MinQTChromaISlice

See merge request jvet/VVCSoftware_VTM!1435

Fix #857: Mismatch for filter length derivation of sub-block motion edges.

See merge request jvet/VVCSoftware_VTM!1466

Fix Ticket #966: Incorrect mv clipping for subpictures in clipMv function

See merge request jvet/VVCSoftware_VTM!1464

  - Add missing "xEdge is equal to 1" and "yEdge is equal to 1" conditions related to eq. 1255 and 1267 in text.
