Also fixes some trace strings according to spec

The value of tile_column_width_minus1[i] shall be in the range of 0 to PicWidthInCtbY-1, inclusive;
The value of tile_row_height_minus1[i] shall be in the range of 0 to PicHeightInCtbY-1, inclusive;

  - Delta POC MSB needs to be coded relative to previous value.  See draft text equation (151).
  - Delta POC MSB is not used correctly in constructRefPicList( ).
  - Delta POC MSB is not used at all in several other places.

to align coding style

Fix #851 : fix rpl_sps_flag[1] and rpl_idx[1] inference in case rpl1_idx_present_flag = 0 (in both SH and PH).

Also use correct default values for JVET_Q0819_PH_CHANGES related flags in Slice.cpp

- don't use SPS in PPS parsing/writing
- create a function for decoder parameter set consistency checks
- fix bug with JVET-Q0413 subpicture parsing changes
- may contain traces of coding style fixes
