Add a Windows crash handler for MSVC And MinGW
Backtraces are not supported on MinGW at the moment, because StackWalker doesn't compile due to a missing dbghelp import library. Also improved the async-safety of output functions. On the Linux side, I noticed a lot of dead-locks and crashes while generating the backtrace lately. In addition, the getOutputInformation kitchen-sink function has been split up a bit and moved to the logging.cpp where it logically belongs.

+/**********************************************************************
+ *
+ * StackWalker.cpp
+ * https://github.com/JochenKalmbach/StackWalker
+ *
+ * Old location: http://stackwalker.codeplex.com/
+ *
+ *
+ * History:
+ * 2005-07-27 v1 - First public release on http://www.codeproject.com/
+ * http://www.codeproject.com/threads/StackWalker.asp
+ * 2005-07-28 v2 - Changed the params of the constructor and ShowCallstack
+ * (to simplify the usage)
+ * 2005-08-01 v3 - Changed to use 'CONTEXT_FULL' instead of CONTEXT_ALL
+ * (should also be enough)
+ * - Changed to compile correctly with the PSDK of VC7.0
+ * (GetFileVersionInfoSizeA and GetFileVersionInfoA is wrongly defined:
+ * it uses LPSTR instead of LPCSTR as first parameter)
+ * - Added declarations to support VC5/6 without using 'dbghelp.h'
+ * - Added a 'pUserData' member to the ShowCallstack function and the
+ * PReadProcessMemoryRoutine declaration (to pass some user-defined data,
+ * which can be used in the readMemoryFunction-callback)
+ * 2005-08-02 v4 - OnSymInit now also outputs the OS-Version by default
+ * - Added example for doing an exception-callstack-walking in main.cpp
+ * (thanks to owillebo: http://www.codeproject.com/script/profile/whos_who.asp?id=536268)
+ * 2005-08-05 v5 - Removed most Lint (http://www.gimpel.com/) errors... thanks to Okko Willeboordse!
+ * 2008-08-04 v6 - Fixed Bug: Missing LEAK-end-tag
+ * http://www.codeproject.com/KB/applications/leakfinder.aspx?msg=2502890#xx2502890xx

+ * http://www.codeproject.com/KB/applications/leakfinder.aspx?msg=1824718#xx1824718xx
+ * Fixed Bug: Compiling with "/Wall"
+ * http://www.codeproject.com/KB/threads/StackWalker.aspx?msg=2638243#xx2638243xx
+ * Fixed Bug: Now checking SymUseSymSrv
+ * http://www.codeproject.com/KB/threads/StackWalker.aspx?msg=1388979#xx1388979xx
+ * Fixed Bug: Support for recursive function calls
+ * http://www.codeproject.com/KB/threads/StackWalker.aspx?msg=1434538#xx1434538xx
+ * Fixed Bug: Missing FreeLibrary call in "GetModuleListTH32"
+ * http://www.codeproject.com/KB/threads/StackWalker.aspx?msg=1326923#xx1326923xx
+ * Fixed Bug: SymDia is number 7, not 9!
+ * 2008-09-11 v7 For some (undocumented) reason, dbhelp.h is needing a packing of 8!
+ * Thanks to Teajay which reported the bug...
+ * http://www.codeproject.com/KB/applications/leakfinder.aspx?msg=2718933#xx2718933xx
+ * 2008-11-27 v8 Debugging Tools for Windows are now stored in a different directory
+ * Thanks to Luiz Salamon which reported this "bug"...
+ * http://www.codeproject.com/KB/threads/StackWalker.aspx?msg=2822736#xx2822736xx
+ * 2009-04-10 v9 License slightly corrected (<ORGANIZATION> replaced)
+ * 2009-11-01 v10 Moved to http://stackwalker.codeplex.com/
+ * 2009-11-02 v11 Now try to use IMAGEHLP_MODULE64_V3 if available
+ * 2010-04-15 v12 Added support for VS2010 RTM
+ * 2010-05-25 v13 Now using secure MyStrcCpy. Thanks to luke.simon:
+ * http://www.codeproject.com/KB/applications/leakfinder.aspx?msg=3477467#xx3477467xx
+ * 2013-01-07 v14 Runtime Check Error VS2010 Debug Builds fixed:
