specific code. As a result of this, HAVE_GTK3 no longer needs to be
exposed.
The use of HAVE_GTK, and HAVE_ GTK3 have been changed to mirror the
method used by HAVE_QT and HAVE_QT5.
On branch gtk3

Env setup for testing package implemented using /etc/profile.d;
Variable with path for all native samples added;
Path for test binaries and test data updated.
(master branch was fixed before, no need to merge this to master!)
- disable openexr (numerous undefined std::min & std::max)
- workaround for two compilator bugs
Update to cmake files for to include minimum versions, and tidy up gtk operation.
Files updated:
CMakeLists.txt:
WITH_GTK now uses Gtk3 by default. If not found then Gtk2 is used.
WITH_GTK_2_X forces Gtk2.x use
cmake/OpenCVFindLibsGUI.cmake
Updated selection logic to implement methodology described above.
Implemented warning if Gtk3 not found (and not overridden)
Implemented error if Gtk does not meet minimum required version
cmake/OpenCVMinDepVersions.cmake
Added minimum Gtk version of 2.18.0
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.
include() doesn't create a variable scope, so the settings of
CMAKE_MODULE_PATH and CMAKE_FIND_ROOT_PATH_MODE_* were polluting
everything included after OpenCVDetectCUDA.cmake.
Also, FindCUDA includes FindPackageHandleStandardArgs, which includes
CMakeParseArguments, which causes warnings related to policy CMP0017.
Setting it to NEW seems safe enough.
The reasons for that are twofold:
1) LINK_PRIVATE is only available since CMake 2.8.7.
2) The way it was used generated a warning because of CMake policy CMP0023:
http://www.cmake.org/cmake/help/v2.8.12/cmake.html#policy:CMP0023
Using LINK_INTERFACE_LIBRARIES actually causes another warning - this time
because of CMake policy CMP0022:
http://www.cmake.org/cmake/help/v2.8.12/cmake.html#policy:CMP0022
I set the policy to OLD, because NEW means subtle changes when compiling
with CMake 2.8.12, and I don't want to research that this close to release.
:-)
I also removed the setting of CMP0003, because it's set by
cmake_minimal_version anyway.
A new option WITH_GTK3 has been added to the cmake configure system to enable compilation under Gtk version 3.The flag HAVE_GTK3 is also introduced to select the new Gtk3 code in the source files. (Gtk2 is disbled when Gtk3 is selected).
window_gtk.cpp has been modified to remove obsolete (and deleted from libgtk 3) and introduce new Gtk3 code in its place when compiled for Gtk3.
To compile for Gtk2, disable WITH_GTK3 in cmake. To build for Gtk3 both WITH_GTK and WITH_GTK3 must be selected.
