iSCSI LUN extents with VirtualDisk (VDI, VHD, VMDK) for istgt

[Ivaylo Ivanov]

I've tried to install for FreeBSD 9.1 from ports with VBOXVD, but the 
following problem occurs:

/usr/ports/emulators/virtualbox-ose/work/VirtualBox-4.2.12/include/VBox/vd.h:182: 
error: expected specifier-qualifier-list before 'PARTITIONING_TYPE'
*** [istgt_lu_disk_vbox.o] Error code 1

Stop in /usr/ports/net/istgt/work/istgt-20121028/src.
