Copied minidump_test.cc from chrome_frame (see http://src.chromium.org/viewvc/chrome/trunk/src/chrome_frame/crash_reporting/minidump_test.cc).
I had to remove the dependency from base (was using FilePath and ScopedHandle, replaced them by standard std::wstring and HANDLE). Also removed the logging and the main from the original files. This will serve as a base for testing breakpad's dump generation. It is kept like this for easier tracking.
