(1) move frame_only_constraint_flag and single_layer_constraint_flag outside the GCI syntax structure into the PTL syntax structure
(2) rename single_layer_constraint_flag to multi_layer_enabled_flag
(3) change ptl_alignment_zero_bit to ptl_reserved_zero_bit

- Rename members of WPScalingParam to conform to guidelines
- Avoid casts from const to non-const types
- Modify getWpScaling function to handle case where the reference
  index is negative (see #733)
- Add helper function isWeighted to determine whether weighting
  parameters are present for any colour component
- Fix some indentation issues

JVET-S0123: Invoke the generation of unavailable reference picture for an IDR picture that has RPLs. Change the process for deriving empty RPLs when sps_idr_rpl_present_flag is equal to 0 and nal_unit_type is equal to IDR_W_RADL or IDR_N_LP to involve pps_rpl_info_in_ph_flag.

JVET-S0124: Add TemporalId, ph_non_ref_pic_flag, and ph_pic_parameter_set_id for generating unavailable reference pictures

Move no_output_of_prior_pics_flag from PH to SH

number of tile in an AU, and a picture might have more than
NUM_TILE_ROWS tile rows.

VUI modifications including VUI length, moving two flags from GCI to
VUI, reordering VUI variables to follow syntax elements

Constraint that no subpicture can be outside the conformance cropping
window + rewrite the conformance cropping window when extracting a
subpicture

JVET-S0160 aspect 1 and aspect 9: inference of pps_loop_filter_across_tiles_enabled_flag and constraint on ph_poc_msb_cycle_present_flag
