771af4f32d Some changes to support mingw-w64
- IPP is disabled by default when compiler is mingw (couldn't make it
work)
- fixed some warnings

7e6947a940 Bugfix for bug #3767
Fixed a memory leak in cap_dshow.cpp in videoInput::setVideoSettingCamera(). The leak was caused by not releasing an IBaseFilter object created in a call to getDevice(). Tho object is now properly released.

(use "git reset HEAD <file>..." to unstage)

	modified:   modules/java/generator/gen_java.py
	modified:   modules/videoio/include/opencv2/videoio.hpp
	modified:   modules/videoio/include/opencv2/videoio/videoio_c.h
	modified:   modules/videoio/src/cap_dshow.cpp
	modified:   modules/videoio/src/cap_pvapi.cpp

Following changes have been made:
1. Some minor bugs have been removed.
2. In the PvAPI module the option CAP_PROP_MONOCROME has been removed because
   this option does not make sense and causes an error if a color camera is used.
3. Instead the new option CAP_PROP_PVAPI_PIXELFORMAT has been added which allows
   to activate the different pixel formats (color modes) of an AVT camera.
4. Since there were two identical defines
   CAP_PROP_MONOCROME = 19
   CAP_PROP_MONOCHROME = 19
   which were also used in the other module DSHOW, the first one with an orthographic
   error has been removed in favor of the second one.

ec93d103b7 Refactored code responsible for printing debug messages in DShow video capture module to reduce footprint in Release mode.
Replace printf function used for diagnostic purposes with dedicated DebugPrintOut function to output debug messages. This function is effective only in Debug mode and its body becomes empty in Release mode to reduce footprint.

c54928e003 Fixed getting CV_CAP_PROP_FOURCC property value
Save selected FCC in order to return proper CV_CAP_PROP_FOURCC property value (currently FCC for RGB24 is always returned).

de0b46a765 Fixed selecting media type in DShow video capture.
Set correct value of sample size when calling IAMStreamConfig::SetFormat function. For non-RGB media type it can be set to zero value.
