Fixed crash in fed when UTF-8 sequence crossed a block boundary.
Also:
* Cleaned up output of drvinfo
* Fixed tefcons when no console-title argument was specified
* Added FSHELL_INCLUDE_TESTS rombuild macro
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)
