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.
