make debball

Note: mainly tested with qemu 1.6

-------------------------
Issues solved from my previous test build report:
-------------
- domU not start with qemu 1.5.1 and more that 2 gb of ram:
   tested on w7 64 bit domU with 4 gb of ram, with built-in qemu 1.3 it 
works,
   while with qemu 1.5.1 doesn't (stops at the beginning, spice client 
show only the lines of seabios version and machine UUID;
   qemu log show nothing more that 2 gb test), while with 2 gb of ram 
works also with qemu 1.5.1
   (SOLVED WITH QEMU 1.6)
-------------
- Starting xendomain with "xl create" show some debug options:

[done].

- nested hvm was bugged: started test it on windows 7 pro 64 domU on 
qemu-xen,
   on xpmode now works also integration features 
(disks,printers,clipboard sharing) and usb passthrough
-------------------------

-------------------------
Old issue:
- Network is not working after restore on Windows domU with qemu-xen and 
gplpv
   Workaround: fixed mac address
-------------
- on W7 pro 64 bit domU error in the begin of qemu log, while domU seem 
to work:
   xc: error: linux_gnttab_set_max_grants: ioctl SET_MAX_GRANTS failed 
(22 = Invalid argument): Internal error
   xen be: qdisk-832: xc_gnttab_set_max_grants failed: Invalid argument
