* Expose more C++ functionality in the Java wrapper of the Mat class
In particular expose methods for handling Mat with more than 2 dimensions
* add constructors taking an array of dimension sizes
* add constructor taking an existing Mat and an array of Ranges
* add override of the create method taking an array of dimension sizes
* add overrides of the ones and zeros methods taking an array of dimension sizes
* add override of the submat method taking an array of ranges
* add overrides of put and get taking arrays of indices
* add wrapper for copySize method
* fix crash in the JNI wrapper of the reshape(int cn, int[] newshape) method
* add test for each method added to Mat.java

* Fix broken test

* make sure that the matrix with more than INT_MAX elements is marked as non-continuous, and thus all the pixel-wise functions process it correctly (i.e. row-by-row, not as a single row, where integer overflow may occur when computing the total number of elements)

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

Added new tests written by Hussein Abdinoor; Added support for new classes in features2d and imgproc

Java API: fixed problems in video and ml modules; generated test stubs for all exported functions (now we have 1701 tests).

Java API: (per code review) adding check (data.length % CvType.channels(t) != 0) for Mat:: put/get, adding 2 tests for them
Testing: 1176/4/580

java tests: Mat.inv and Mat.cross implemented, almost all Mat tests finished except put, get and dispose
