RADL and RASL constraints

[abe.kiyo]

In "3 Definitions", RADL and RASL constraints should be removed according to JVET-O0147 and JVET-O0226.

3.101 random access decodable leading (RADL) picture: A coded picture for which each VCL NAL unit has nal_unit_type equal to RADL_NUT.

NOTE – All RADL pictures are leading pictures. RADL pictures are not used as reference pictures for the decoding process of trailing pictures of the same associated IRAP picture. When present, all RADL pictures precede, in decoding order, all trailing pictures of the same associated IRAP picture.

3.103 random access skipped leading (RASL) picture: A coded picture for which each VCL NAL unit has nal_unit_type equal to RASL_NUT.

NOTE – All RASL pictures are leading pictures of an associated CRA picture. When the associated CRA picture has NoIncorrectPicOutputFlag equal to 1, the RASL picture is not output and may not be correctly decodable, as the RASL picture may contain references to pictures that are not present in the bitstream. RASL pictures are not used as reference pictures for the decoding process of non-RASL pictures. When present, all RASL pictures precede, in decoding order, all trailing pictures of the same associated CRA picture.

Good catch! Thanks! Those should indeed be removed or updated.
