Set SPS::m_numRPL0/1 equal to num_ref_pic_lists_in_sps instead of num_ref_pic_lists_in_sps + 1.
This allow to align the parsing of slice_header with specification when
getNumRPL0() or getNumRPL1() are called (correspond to the condition on
num_ref_pic_lists_in_sps in the specfication).

- Fix the entry points
- Put some validation for rectangular slice
- Bug fix for N0124 signalling for number of bits to signal bottomrightidx

Align with specification the coding of pps_virtual_boundaries_pos_x and pps_virtual_boundaries_pos_y

Software implementation for N0278:
1. Added VPS encoding in encoder
2. Add new project StreamMergeApp to N-to-1 bitstream merge
3. Changed decoder to support only decoding the specified layer stream

Philip Cowan authored 5 years ago and Karsten Suehring committed 5 years ago

Implement N0124, proposal 1, an inference rule for when single_tile_per_tile_group_flag is not present.

According to specification, alf_luma_coeff_delta_sign = 1 means that filtCoeff is negative. Idem with alf_chroma_coeff_delta_sign and AlfCoeffC.

According to specification, alf_ctb_flag is parsed for Cb when (slice_alf_chroma_idc = 1 or slice_alf_chroma_idc = 3), and for Cr when (slice_alf_chroma_idc = 2 or slice_alf_chroma_idc = 3).

- create own files for HRD classes
- rename HRD to HRDParameters
- create HRD class that can hold all HRD related parameters as base for encoder/decoder specific implementations

- includes special handling for dps ID equal to zero (JVET-N0869)
- writing of parameter set can be enabled by parameter EnableDecodingParameterSet

implements:
- splitting tiles into bricks
- raster-scan tiles
- uniform and non-uniform splits
- all tiles/bricks in one slice
- each brick one slice
- PPS syntax

missing:
- rectangular tiles
- slice header syntax

further todo:
- rework slice mode 2 to use multiple tiles for byte size matching
- lots of renaming (tile->brick)
