Log Message:
Add SDLT320 to the list of drives using DLT4000Eject()
Do not pass the element descriptor size to SCSI_ReadElementStatus();
SCSI_ReadElementStatus() will then issue a SC_COM_RES to know how much space
it needs to allocate, then issue a second one with the proper size.
Fix problems with newer changers, which returns a descriptor status larger
than sizeof(DataTransferElementDescriptor_T).
These changes makes the Overland neo2000/SDLT320 work with amanda.
Ride the libtool PKGREVISION bump.
