Subject: Bug 1021: Add OculusSDK binding / Basic OVR support

Bring-up test only initializes the ovrHmdHandle
data structure by OVR native code.
    See com.jogamp.oculusvr.OVRVersion

Current evaluation build compiles all OVR-SDK source
files itself w/o using provided libovr.a.
We also skip the GL dependent renderer of the SDK,
i.e. we prefer to utilize our JOGL 'barrel distortion' renderer.
This eases the 'chicken-egg' problem of OVR SDK dependencies,
i.e. libGL, libGLESv2 .. etc

Since the OVR source code is C++, we may still have to figure out
how to / and whether we shall link libstdc++ statically
to remove platform dependencies.
Right now we link libstdc++ statically if using GCC,
see  make/build-oculusvr.xml (hackish .. TODO: better way to include all symbols).

Same consideration applies to GNU/Linux and libudev.so dependency,
since there are:
    - libudev.so.0 and (Older distri's)
    - libudev.so.1 (Debian8, ..)

...

Produced JAR artifacts are
    - jar/atomic/oculusvr.jar
    - jar/atomic/oculusvr-natives-<os.and.arch>.jar

i.e. only in 'atomic' variants to not bloat the default 'all' JAR files.

....

make/build-oculusvr.xml Notes:
    - Currently native build only enabled on GNU/Linux (isLinux)
    - Force disable native build via property 'c.build.oculusvr.skip'
