Ashok Bhat ab6fc2a86f Use long for pointers in opengl/EGL classes
EGL classes in frameworks/base have to be updated to support
64-bit platforms. Key changes in the EGL classes include

[x] EGLObjectHandle class - EGLObjectHandle class has two public
    methods (constructor and getHandle) that assume handles are
    32-bit. They have not been changed. Instead, two new hidden
    methods (EGLObjectHandle(long) and getNativeHandle) have been
    added.

[x] EG14 class - Two public methods eglGetDisplay and
    eglCreatePbufferFromClientBuffer assume that handles are 32-bit.
    They have been changed to throw unsupported operation exception
    on non 32-bit machines. Two new methods eglGetDisplay(long)
    and eglCreatePbufferFromClientBuffer(...long buffer..) have
    been added to support 64-bit handles.

To allow the above changes in frameworks/base EGL classes,
corresponding code generation mechanism in frameworks/native has
been updated.
