(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

JVET-S0066: gci_three_minus_max_log2_ctu_size_constraint_idc and gci_no_luma_transform_size_64_constraint_flag

Also fixes #738

- 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

Align software with specification fix #1247

Move the signalling of aps_params_type to an earlier position and change the signalling of aps_adaptation_parameter_set_id

AHG Recommendation (cleanup): Just change the order to put the type before the ID.

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

JVET-S0183 VPS information signalling modification: signal num_output_layer_sets_minus1 as num_output_layer_sets_minus2

- fix two typos
- avoid global constant VCL_ASSOCIATED_SEI_LIST_SIZE

Made changes to constraints for chroma format and bit depth, according
to meeting notes on JVET-S0094.
Also added encoder and decoder side checks.

JVET-S0181: Reference picture list information signalling cleanup - signal ltrp_in_slice_header_flag[listIdx][rplsIdx] only when num_ref_entries[listIdx][rplsIdx] is greater than 0 in addition to other conditions.

JVET-S0185_PROPOSAL1: SEI picture timing cleanup, put syntax element pt_cpb_removal_delay_minus1[] first, followed by similar information for sub-layers, followed by pt_dpb_output_delay.

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.

Fix for Visual Studio compiler warnings and errors when JVET_R0351_HIGH_BIT_DEPTH_ENABLED is enabled
