thompsa 6710b5f115 Use the EVENTHANDLER system to hook into the usb device configuration and
perform a function such as ejecting a 3G autoinstaller disk. The eventhandler
system properly tracks threads and is safe to unload, remove the
setting/clearing of a function pointer in the kernel by u3g(4) which included a
tsleep for safety.
