Fixed threadpool hang and added lots of smoketests.
* Fixed bug in threadpool logic when calling CleanupAnyWorkersSharingAllocator - this was deleting the worker's thread death notifier in the context of a worker thread (which is only allowed from the context of the main thread).
* Added lots more smoketests
* Added --overwrite option to fzip (previously unzipping would always overwrite)
These two executables exists to allow fshell to eclipse the ROM based "econs.dll". This can't be done
within the .SIS file because the app installer doesn't allow ROM files to be eclipsed.
fshell_inst.exe copies "<install_drive>:\sys\bin\iocons.dll" to "<install_drive>:\sys\bin\econs.dll".
It is launched by the tool-kit .SIS file at install time.
fshell_uinst.exe deletes "<install_drive>:\sys\bin\econs.dll".
It is launched by the tool-kit .SIS file at uninstall time.
