Frequently used OpenGL ES methods whitelisted for fast JNI path 

The patch lists ~70 methods of OpenGL ES 2.0 wrapper as fast JNI.
This significantly reduces JNI overhead for OpenGL Java applications.
Which results in faster rendering and reduced JANK (e. g. 10 % Jank
reduction  on Google Maps).

None of the whitelisted methods can block forever according to OpenGL
spec. So, this change is safe from fastJNI point of view (can not
introduce any deadlocks). As measured is a separate experiemnt
the whitelisted methods take less than 1 ms in vast majority (99.9+) of the
cases, and always complete within 100 ms.  As shown in this thread
https://soco.intel.com/thread/766188

 such level of delays should not
have any practical impact on GC pauses, but reduces the JNI overhead
significantly.
