EGL Display Lifecycle Robustness Patch (impl. workaround)

Added EGLDisplayUtil helper class managing the lifecycle of the EGL display handle recursively.

This class is required, due to implementation bugs within EGL where EGL.eglTerminate(long)
does not mark the resource for deletion when still in use, bug releases them immediatly.

This fixes unit test com.jogamp.opengl.test.junit.jogl.acore.TestInitConcurrentNEWT
on Linux ARM w/ Omap4 and Tegra2.
