x265: updated to 3.3

Version 3.3

New features
Adaptive frame duplication to identify and skip encoding of near-identical \ 
frames and signal the duplication info to the decoder via pic_struct SEI. \ 
frame-dup to enable frame duplication and --dup-threshold to set the threshold \ 
for frame similarity (optional).
Boundary aware quantization to cut off bits from frames following scene-cut. \ 
This leverages the inability of HVS to perceive fine details during scene \ 
changes and saves bits. --scenecut-aware-qp , --scenecut-window and \ 
--max-qp-delta to enable boundary aware frame quantization, to set window size \ 
(optional) and to set QP offset (optional).
Improved scene-cut detection using edge and chroma histograms. --hist-scenecut \ 
to enable the feature and --hist-threshold (optional) to provide threshold for \ 
determining scene cuts.

Enhancements to existing features
--hme-range to modify search range for HME levels L0, L1, and L2.
Improved performance of AQ mode 4 by reducing memory foot print.
Introduced --analysis-save-reuse-level and --analysis-load-reuse-level to \ 
de-couple reuse levels of --analysis-save and --analysis-load. Turnaround time \ 
of ABR encoding can be reduced by properly leveraging these options.

Encoder enhancements
Improved VBV lookahead to eliminate blocky artifacts in Intra frames coming \ 
towards end of the title.

API changes
New API function x265_encoder_reconfig_zone() to invoke zone reconfiguration \ 
dynamically.
Renamed --hdr to --hdr10. --hdr will be deprecated in the upcoming major release.
Renamed --hdr-opt to --hdr10-opt. --hdr-opt will be deprecated in the upcoming \ 
major release.
Additions to x265_param structure to support the newly added features and \ 
encoder enhancements.
