This patch moves all static initialization of GfxDriverInfo and DeviceFamily
classes to the point that they're actually used. It also converts all static
GfxDriverInfo arrays into nsTArray<GfxDriverInfo> so that they can be used
interchangeably with the downloadable blocklist.
This patch also introduces a new phase of blocklist checking called
BEING_PROCESSED, which is the status set when a blocklist check is currently
being processed. NO_INFO now only means that we have confirmed that a device is
not blocked.
Refactored Windows-specific code for blocklisting GPUs to GfxInfoBase so that it
could be re-used by every platform. Also enabled all downloaded blocklist code on X11 (Linux) and Cocoa (Mac)
but not yet on Android.
This patch makes GetShouldAccelerate directly call GetData, just before the place where we call GetFeatureStatus, which we know is reached.
Initially I considered instead calling GetData from GfxInfo::Init() but that turned out to be a bad idea: Init() is called by the factory constructor, which is called significantly earlier in the startup process. We want to call GetData as late as possible, just when we need it, to maximize chances that the glxtest process be already finished by the time we waitpid() it, so that we don't end up wasting time waiting for it.
