- Add special case handling when submodule has the same name as parent
- `PyDict_SetItemString` doesn't steal reference, so reference count
  should be explicitly decremented to transfer object life-time
  ownership
- Add sanity checks for module registration input
- Add Python 2 and Python 3 reference counting handling

G-API: Wrap GStreamerSource

* Wrap GStreamerSource into python

* Fixed test skipping when can't make Gst-src

* Wrapped GStreamerPipeline class, added dummy test for it

* Fix no_gst testing

* Changed wrap for GStreamerPipeline::getStreamingSource() : now python-specific in-class method GStreamerPipeline::get_streaming_source()

* Added accuracy tests vs OCV:VideoCapture(Gstreamer)

* Add skipping when can't use VideoCapture(GSTREAMER);
Add better handling of GStreamer backend unavailable;
Changed video to avoid terminations

* Applying comments

* back to a separate get_streaming_source function, with comment

* Fix support objdetect module for UWP

* Fix define module for objdetect

* Remove conditional compilation from public headers

* coding style, eliminate warnings

Comment from Python documentation:
Unlike other functions that steal references, `PyModule_AddObject()` only
decrements the reference count of value on success.
This means that its return value must be checked, and calling code must
`Py_DECREF()` value manually on error.
