Other drivers could be tested if available. Flags are +kept independent for linux, where this feature has to be enabled before +actually using it. This should not change how other OSes use the flags +already, the new flags will show at the buttom on the section of unavailable +experiments + +The changes cover a range of compiler pre-processor flags to enable the stack. +It moves the presandbox operations to the vaapi_wrapper class as the hook function +is available there. vaInit will open driver on the correct installed folder. + +chrome flags consolidtation into only two flags for linux. Mjpeg and accelerated +video are used. The other flags are kept for ChromeOS and other OSes. + +Developer testing was made on skylake hardware, ChromeOS and Ubuntu. + +BUG=NONE +TEST=subjective testing with VAVDA,VAVEA and VAJDA, autotest
