x265: updated to 3.4

Version 3.4

New features
------------
Edge-aware quadtree partitioning to terminate CU depth recursion based on edge \ 
information. --rskip level 2 enables the feature and --rskip-edge-threshold \ 
denotes the minimum expected edge-density percentage within the CU, below which \ 
the recursion is skipped. Experimental feature.
Application-level feature --abr-ladder for automating efficient ABR ladder \ 
generation. Shows ~65% savings in the over-all turn-around time required for the \ 
generation of a typical Apple HLS ladder in Intel(R) Xeon(R) Platinum 8280 CPU @ \ 
2.70GHz over a sequential ABR-ladder generation approach that leverages \ 
save-load architecture.

Enhancements to existing features
---------------------------------
Improved efficiency in 2-pass rate-control algorithm. The savings in the bitrate \ 
is ~1.72% with visual improvement in quality in the initial 1-2 secs.

Encoder enhancements
--------------------
Faster ARM64 encodes enabled by ASM contributions from Huawei. The speed-up over \ 
no-asm version for 1080p encodes @ medium preset is ~15% in a 16 core H/W.
Strict VBV conformance in zone encoding.

Bug fixes
---------
Multi-pass encode failures with --frame-dup.
Corrupted bitstreams with --hist-scenecut when input depth and internal \ 
bit-depth differ.
Incorrect analysis propagation in multi-level save-load architecture.
Failure in detecting NUMA packages installed in non-standard directories.
