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

add braces around the single line condition

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.

VVC follows the concept that parsing of SEIs shall be independent of parameter sets

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.
