Changeset 65057 in vbox for trunk/include/VBox

Message:

Devices/Storage: Kill the host SCSI passthrough driver, wasn't really working ever (just a simple proof of concept only working on Linux and very limited command set). Can't be used now anyway after the I/O rework because the PDMISCSICONNECTOR is obsolete and not used by any SCSI controller so the driver must be rewritten in case we want SCSI passthrough at some point.
