- allow cmake to check sanity of vsx aligned ld/st
 - force universal intrinsics v_load_aligned/v_store_aligned
   to failback to unaligned ld/st if cmake runtime vsx aligned test fail

* Fixed bug that made cuda::filter give corrupted output when different filters called in different threads. This was due to use of global texture variable shared by all filters.

* REV: fixed tab issue for opencv coding style...

The big endian data in the tiff_sample_data array was never being tested.  This could be observed by e.g. changing the 9th byte in the big endian data from 0xde to something that should fail the test, e.g. 0xdd, and the test would still pass even though it should fail.

* 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
