WITH_WINRT -> ENABLE_WINRT_MODE;
Some temporary char* replaced with Ptr<char>;
Build fix for regular WIN32;
Windows Platform SDK and MSVC search added to cmake;
Warinig fixes.

Additional CMAKE flag WITH_WINRT added.

Also, removed needless check of BUILD_SHARED_LIBS in core; in that case,
only the current module's library type matters.

I've left HAVE_LIBPTHREAD as a CMake variable, since TBB's build depends on it.

Some macros in internal.hpp depended on HAVE_ALLOCA_H, but they were, in turn,
unused, so I've just deleted them all.

Introduced new Java API
void org.opencv.core.Core.setErrorVerbosity(boolean verbose)
used to suppress output to stderr from OpenCV's asserts

* use OPENCV_TEMP_PATH environment variable on all platforms
* fix cleanup after OpenCV tests on Windows
* add --list flag to output names of all tests found
* do not override user-passed --perf_min_samples and --perf_force_samples
  options by --check flag
* fix complier checks inside run.py

Created temporary files are now deleted in Win32.

added cross-platform Mutex implementation; enable platform-native (GDC/Concurrency) parallel_for_ implementation when TBB is not installed.

fixed gpu module error reporting
added asynchronous version of some functions
