USB retweaking: Take out the USB_REQUEST/RELEASE_DISK scheme and simply ask the USB core whether or not any drivers require exclusive access at the moment of connect. Doing anthing else just produces nasty effects on Windows because it expects some communication just for enabling the PHY and not allowing it to mount volumes if a thread doesn't ack causes annoying error message boxes. Make behavior of each USB type identical from the system perspective. Some miscellaneous changes (simplify, ata->storage naming, define only used USB_* enums values were possible).
