- See ticket #1299

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.

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.

Fix #1409: Don't scale 15/16 bit sequences to lower bit depths if JVET_R0351_HIGH_BIT_DEPTH_ENABLED is not set

Even without xWriteAPS, the functionality removing non-ref APS is already supported.

all of the suggestion that is from S/W coordinator are adopted.

1. modify doc/software-manual.tex

2. replace 2D array [64][64] for this MR with vector

3. fix Bug in bitstreamExtractorApp regarding removing APS.

- Add brace after conditions or loop in order to enclose single line.

implement JVET-S0219,
in order to implement extraction process that is decided to adopt by JVET_S0219, the equation (32) in the SPEC(JVET-S2001_vG) is needed to integrate. for this, JVET-R0193 and JVET-S0141 item47 is also implemented here.
please refer below meeting note for each aspect.
[JVET-S0219] Enable removal of parameter sets (i.e., PPS and APS) in non-output layer that is not used as reference for decoding of pictures in output layers during extraction process

AHG Recommendation (cleanup): Adopt APS aspect only.

[JVET-R0193] Signal max_tid_il_ref_pics_plus1 value separately for each direct reference layer of a layer, i.e. max_tid_il_ref_pics_plus1[ i ][ j ] for each direct reference layer j less than i, instead of single  max_tid_il_ref_pics_plus1[ i ]

AHG Recommendation (cleanup): Adopt. Text was provided in the contribution, and the authors are to supply the software

[JVET-S0141 item 47] In the general sub-bitstream extraction process, specify the conditions under which an output sub-bitstream is required to be a conforming bitstream such that the value of tIdTarget is specified to be in the range of 0 to vps_ptl_max_tid[ vps_ols_ptl_idx[ targetOlsIdx ] ], inclusive (instead of 0 to 6 inclusive)? (JVET-S0158 aspect 1)
