* Remove outdated code from errorasm/exceptasm
* Delete osAckRamromWrite and osAckRamromRead, old unused stubs
* Remove osDriveRomInit, as this is old OS2.0I code that's not supposed to be in later versions
* Remove error.c as this was removed in 2.0J and duplicates other code
* Remove old libleo code which was only in 2.0I
* Remove mtxutil and mtxcatl as these are duplicate of functions rewritten in mgu
* Remove dump_gbi as it's literally all #if 0
* Remove GIO functions as they're leftover Indy board code
* Remove leftover Partner-N64 code
* Prevent debug code from being included in ROM version
* Remove testhost due to being a stub file with nothing in it
* Remove osExit as it's indy board code useless on non-indy
* Add ifdef _FINALROM to dumpturbo
* All debug code included in non ROM builds checked and #ifndef _FINALROM added where needed
* Add missing ifdef and endlines
* Restore libleo code (will be taken care of in a seperate PR)
