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.

Implement VideoCapture::get, CvCapture::getProperty, IVideoCapture::getProperty as constant methods.

BUGFIX: Fixed bugged when setting PVAPI property CV_CAP_PROP_FRAME_HEIGHT.

Added get and set for additional PVAPI properties: DecimationHorizontal, DecimationVertical, BinningX, BinningY

Added "PVAPI_" prefix to FrameStartTriggerMode definition

All tests passed!

- Added Gain control
- Changed default acquisition mode to grayscale
- Fixed a signed/unsigned compare issue
- Implemented frame resizing
- Implemented automatic buffer resizing on frame resize
- Corrected camera initialization so that it attempts to put the camera in Mono8
  but does not fail if this doesn't succeed.

do not use WIN64/_WIN64 anymore - CMake did not set it anyway. Use WIN32 + __x86_64 or _M_X64 instead. Also, make VideoInput optional (WITH_VIDEOINPUT=ON/OFF) => now Mingw-dw2 can build OpenCV

Adapted mtu and packed size
Some minor fixes in gstreamer because not implemented support of v4l v4l2 in the wrapper
default beahvior must be v4l v4l2 or libv4l backends
