JVET-S0096 aspect 1:  a RPL constraint

JVET-T0065: Add level 6.3

JVET-S0084 and JVET-S0110: Specify RPL constraint on RADL picture

JVET-R0266 proposal 5: no_gdr_constraint_flag semantics

Fix out of bounds access after merging !1875 (JVET-S0163: On target OLS and sublayers for decoding)

See merge request jvet/VVCSoftware_VTM!1931

Change default of gci_present_flag

See merge request jvet/VVCSoftware_VTM!1929

fix placement of JVET_S0078_NOOUTPUTPRIORPICFLAG macro

See merge request jvet/VVCSoftware_VTM!1930

GCI is not initialized in VPS or DCI. This leads to sending lots of flags with "no constraint" values. Setting gci_present_flag to 0 has the same semantic meaning.

JVET-S0078-Rebased: Handling NoOutputOfPriorPicFlag

See merge request jvet/VVCSoftware_VTM!1927

JVET-S0163: On target OLS and sublayers for decoding (Operating Point Information OPI NAL Unit)

Fix: set the default for MaxTidILRefPicsPlus1 to 7

See merge request jvet/VVCSoftware_VTM!1926

This results in setting max_tid_ref_present_flag to 0 and not sending the syntax element.

The previous default of -1 would try to send (uint32_t)-1 in three bits.
