Allowing symbian cleanup code in thread started and finished slots
The run() function of QThread was inside a TRAP, but the started() and finished() signals were emitted outside of a TRAP so could not contain Symbian cleanup stack code. This broke compatability with some apps, as the older pthread based implementation had the whole main thread function running inside a TRAP. The started and finished signals are now emitted inside TRAPs, with enhanced leave/exception handling code.
