Update android+AsyncServiceHelper.java

small formatting fixes

1) Fixed deadlock if camera is started and stopped immediately
2) Invalid pattern usage of Object.wait(). Refer to "spurious wakeup": http://docs.oracle.com/javase/8/docs/api/java/lang/Object.html#wait
3) Fixed buffer usage:
  a) fix eliminates processing of zero NV12 (green in RGB) first frame
  b) latest ready frame is delivered for processing (not previous)

The crash was cased by massive Mat objects leak in NativeCameraView class.

(cherry picked from commit dbe76342)

EMBED_CUDA and FORCE_EMBED_OPENCV flags added to cmake macro add_android_project;
INSTALL_CUDA_LIBRARIES option added to OpenCV.mk
opencv_dynamicuda library installation with enabled OPENCV_INSTALL_MODULES flag fixed;
CUDA initialization apportunity added to OpenCVLoader.initDebug();
Tutorial-4-CUDA sample reimplemented with static OpenCV and CUDA initialization.
(cherry picked from commit 6ae4a9b0)

CV_CAP_PROP_SUPPORTED_PREVIEW_SIZES_STRING property is not supported
by all VideoCapture backends. Some backends can return 0.0 or -1.0.(cherry picked from commit c41e8006)

New version of Java wrappers' generator uses different wrappers for VideoCapture
on Android and desktop to prevent binary compatibility issues.

It increases performance on some devices like Nexus4.
Target Android SDK version increased up to 14.

- enable auto-wrap of VideoCapture;
- minor refactoring of generated code templates.

OpenCV Version 2.4.6;
OpenCV Manager Version 2.8;
Doc fixes.
