Bug 948 - NVIDIA 331.38 (Linux X11) EGL impl. only supports _one_ EGL Display via eglGetDisplay(..)

NVIDIA 331.38 (Linux X11) EGL impl. only supports _one_ EGL Display via eglGetDisplay.

  - Subsequent eglGetDisplay(..) calls fail.

  - Using the same 'global' egl-display does work though

Remedy: Add 'GLRendererQuirks.SingletonEGLDisplayOnly'

Detection of quirk is done as usual in GLContextImpl.setRendererQuirks(..),
and EGLDrawableFactory passes the quirk, if detected, down to EGLDisplayUtil.
The latter implements the singleton eglDisplay handle.

EGLDisplayUtil: Cleaned up ..
  - EGLDisplayRef employs the reference handling incl. eglInitialize(..) and eglTerminate(),
    as well as the new singleton quirk.

  - Mark all internal methods 'private',
    to remove possible [untested] sideffects.
