Changes

GLhandleARB set to void * on OS X, unsigned int everywhere else

The OpenCL headers on OS X include gltypes.h, which defines
GLhandleARB as void *, but the stub headers gl3.h and glext.h
in JOCL were defining it as unsigned int. Put in a typedef
to match how Khronos fixes the problem. See
http://sourceforge.net/p/glew/bugs/206/,
https://bitbucket.org/alfonse/glloadgen/issue/33/mac-compilation-error,
https://www.opengl.org/registry/api/GL/glext.h, and
https://www.khronos.org/bugzilla/show_bug.cgi?id=762 for more
information.

Add debug targets to match those in gluegen and jogl

Remove stub includes that are duplicates of gluegen's and jogl's

Removes jocl stub includes that are already defined in gluegen and jogl,
and refers to those in gluegen and jogl instead. Requires the
literalInclude parameter to the gluegen Ant task, since it must now
refer to files outside the jocl project.

Remove obsolete Netbeans build files

The new Jogamp standard Ant build has been working correctly for a while
now, so we can delete the old Netbeans build files safely.

Include Khronos derived glcorearb.h before cl_gl.h, avoiding typedef mismatch w/ APPLE's GL

LLVM's clang reports a typedef mismatch of GLintptr and GLsizeiptr
between the Khronos derived glcorearb.h (from JOGL) and APPLE's gltypes.h when producing 32bit builds.

I.e. Khronos uses ptrdiff_t (aka 'int' on 32bit), where APPLE uses intptr_t (aka 'long' on 32bit).

On OSX 32bit both ('int' and 'long') have the same sizeof value, i.e. 4 bytes,
see below, hence the ABI is compatible!

However, clang produces a typedef mismatch.

Fix includes the Khronos derived (JOGL) glcorearb.h before cl_gl.h,
hence favors the former 'canonical' definition.
