Kernel/Tools: Improved OS/2 exception handling:

  • Moved the excpetion handler code from the kernel module to the tools module (defines are now in qt_os2.h instead of qwindowdefs_pm.h);
  • QT_PM_NO_SYSEXCEPTIONS is renamed to QT_OS2_NO_SYSEXCEPTIONS;
  • Added the QtOS2SysXcptMainHandler stack-based class to correctly install the exception handler on the main thread, as well as provide an optional callback.
  • Property svn:keywords set to Id
