The changes over HM-16.7+SCM-5.4 are:
 
•	JCTVC-V0034  : Palette encoder improvement for 4:2:0.
•	JCTVC-V0040  : Enable by default the method in JCTVC-U0095 on fast encoder for ACT and intra mode.
•	JCTVC-V0041  : Constrain the range of escape values.
•	JCTVC-V0042  : Allow zero size palette in PPS.
•	JCTVC-V0043  : Restriction for maximum palette predictor size.
•	JCTVC-V0048  : Relax 8x8 bi-bred restriction based on mv's and temporal referencing.
•	JCTVC-V0049  : Round merge MVs when ref picture is curr pic.
•	JCTVC-V0056  : Relax 8x8 bi-bred restriction based on the value of TwoVersionsOfCurrDecPicFlag. 
•	JCTVC-V0065  : Modified formula for computing PaletteMaxRun considering copy_above_indices_for_final_run_flag.
•	JCTVC-V0066  : Remove special treatments of IBC as different from inter in the case of CIP.
•	Misc. – Bug fix for delta QP for palette mode. 

SCC: disable the macro of SCM_V0057_STORAGE_BOTH_VERSIONS_CURR_DEC_PIC as it depends on SCM_U0181_STORAGE_BOTH_VERSIONS_CURR_DEC_PIC.

SCC: disable SCM_U0181_STORAGE_BOTH_VERSIONS_CURR_DEC_PIC macro, as it breaks the decoding of conformance bitstreams.

SCC: Integration of JCTVC-V0057: DPB considerations when current picture is a reference picture. Patch from: Xiaozhong Xu <xiaozhong.xu@mediatek.com>.

SCC: Fix the integration of JCTVC-U0181: storage of both versions of the current decoded picture into the DPB, treating pictures with in-loop filtering on/off differently, and increase the value of maxDpbPicBuf equal to 7 for profiles supporting IBC. Original patch from: Xiaozhong Xu <xiaozhong.xu@mediatek.com>.

SCC: Integration of JCTVC-V0034: take into account whether pixel's chroma matters. Patch from: GISQUET Christophe <Christophe.Gisquet@crf.canon.fr>.
