Some of functions were enabled on Qualcomm S800 by changing grid size;
OpenCL kernel grid size unification for different platfroms;
Test pass rate improvements by inclreasing threshold;
Some tests were disabled for Android;
run.py was adopted for devices with brackets in in name.

Previously, run.py would assume that the opencv_java library is in the
same directory as the tests, which is only true on Windows.

The library path depends on the build configuration, which may not be
known until the actual build (e.g. with the Visual Studio generators),
so it can't be stored in the CMake cache for run.py to read. I didn't
want to hardcode into run.py where the library is on each platform,
either. So that's why I used the current scheme with the properties
file. It also makes running the tests without run.py a little easier.

Also, shrunk the corresponding column and the test name column.

Now it can determine, without looking at the file name, both the module
name and the configuration name (the latter with a little help from the
configuration file).

* In comparison column headers, switched the order of labels, so that
  it's "to" vs "from".

* When a test was present, but not run successfully, put its status in
  the corresponding cell instead of coloring it gray.

Otherwise, Excel ignores line breaks in them.

Also, removed the one from modules/python/src2/cv.py and cleared its
executable bit, since it's not a script.

Legend for new column is:
* FASTER - strong speedup
* faster - spedup is detected but it is unreliable
* <empty> - no change in speed
* slower - slowdown is detected but it is unreliable
* SLOWER - strong slowdown
