Create EGL 1.4 implementation by merging eglrefimpl and EGL from sfopenvg Subject to some fixes in uiresources and uiaccelerator, this version removes the EGL 1 panics. A quick attempt to use the compositor renderstage wasn't successful, but not apparently due to EGL issues. There are a lot of RDebug::Printf statements still in this code, which will be removed in the next commit.

Make sure the syborg version of the openwfc adaptation is used
