JVET-R0483 Comb 4: R0049 + R0271, only R0049 method 3 aspect (Skip signaling sh_ts_residual_coding_disabled_flag when sps_transform_skip_enabled_flag = 0, also proposed in R0068, R0097, R0142, R0153) as R0271 has its own macro

Fix parsing dependencies in the VUI syntax by moving the
general_progressive_source_flag and general_interlaced_source_flag to
the VUI

JVET-R0113: Conditional signaling of loop_filter_across_tiles_enabled_flag and the 6 PPS PH/SH location flags

Condition presence of sps_inter_layer_ref_pics_present_flag on
sps_video_parameter_set_id

JVET-R0225: Use two separate flags (one for Cb, one for Cr) to replace ph_alf_chroma_idc in PH and sh_alf_chroma_idc in SH
