Adding capability to parse subsections of a byte array in Java bindings (#10489)

* Adding capability to parse subsections of a byte array in Java bindings. (Because Java lacks pointers. Therefore, reading images within a subsection of a byte array is impossible by Java's nature and limitations. Because of this, many IO functions in Java require additional parameters offset and length to define, which section of an array to be read.)

* Corrected according to the review. Previous interfaces were restored, instead internal interfaces were modified to provide subsampling of java byte arrays.

* Adding tests and test related files.

* Adding missing files for the test.

* Simplified the test

* Check was corrected according to discussion. An OutOfRangeException will be thrown instead of returning.

* java: update MatOfByte implementation checks / tests

Bitwise "and false" is always false.

OpenCV 3.4.0-rc

Add Android Mat constructor with support for native buffer (#10050)

Previous commit, 6f39f9a6, tries to fix the color issue for emulator. But the condition for detecting emulator is incomplete, e.g. it stops working for emulators using Google Play, whose Build.BRAND=="google". https://stackoverflow.com/a/21505193 shows a more accurate condition for this.

* Introduced OSGi Blueprint XML file and Bean class too automatically load the native library.

* Introduced integration testing module to deploy to Karaf OSGi implementation.

* Clears library executable stack flag during build.

* Updated README document.

Synchronizing against non-final fields is advised against.

* Use the YV12 format in the Android emulator to avoid image issues

* Removed trailing spaces

* Added exception in else case

* Removed tab

3.2.0-rc

(2.4) Backports from master branch (#7854)

They were issued for every frame retrieved - even in a release build.

refactored; added Camera2, notify callbacks, front/back maxCamera sizes; disable new stuff if target API < 21

Corrected typo and unused imports

a simple sample will look like:

```java
public class MainActivity extends Activity implements CameraGLSurfaceView.CameraTextureListener {

	CameraGLSurfaceView mView;
	ByteBuffer buf;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
                WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

        mView = new CameraGLSurfaceView(this, null);
        mView.setCameraTextureListener(this);
        setContentView(mView);
        buf = ByteBuffer.allocateDirect(1920*1080*4);
    }

    @Override
    protected void onPause() {
        mView.onPause();
        super.onPause();
    }

    @Override
    protected void onResume() {
        super.onResume();
        mView.onResume();
    }

	@Override
	public void onCameraViewStarted(int width, int height) {
		// TODO Auto-generated method stub

	}

	@Override
	public void onCameraViewStopped() {
		// TODO Auto-generated method stub

	}

	@Override
	public boolean onCameraFrame(int texIn, int texOut, int width, int height) {

		int w=width, h=height;
		/*

		/*

		GLES20.glActiveTexture(GLES20.GL_TEXTURE0);
    	GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, texOut);
		GLES20.glCopyTexImage2D(GLES20.GL_TEXTURE_2D, 0, GLES20.GL_RGBA, 0, 0, w, h, 0);
		return true;
		*/

		// option 3:
		// read, modify and write back pixels
		GLES20.glReadPixels(0, 0, w, h, GLES20.GL_RGBA, GLES20.GL_UNSIGNED_BYTE, buf);

		buf.rewind();
		// red line
		for(int i=0; i<h; i++) {
			buf.position(w*4*i+i*4);
			buf.put((byte) -1);
			buf.position(w*4*i+i*4+4);
			buf.put((byte) -1);
		}
		buf.rewind();

		GLES20.glActiveTexture(GLES20.GL_TEXTURE0);
    	GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, texOut);
		GLES20.glTexSubImage2D(GLES20.GL_TEXTURE_2D, 0, 0, 0, w, h, GLES20.GL_RGBA, GLES20.GL_UNSIGNED_BYTE, buf);
		return true;
	}
}
