New XS_SET_TARGET
Stubdomains (and probably other domain disagregation elements too)
need to be able to tinker with another domain. This adds
XS_SET_TARGET so that XenStore allows domains to have permissions on
files on which the "target" has permissions. This also adds
xs_set_target, called by the domain builder when the 'target' option
is used in the configuration.

hvm, ioemu: Fix the ide/cdrom emulation error on FC7 guest.
The new libata-eh in the Linux kernel is throwing a fit over the QEMU
cdrom device for two reasons:
1) DRQ can be set with ERR_STAT set. This is a violation of the ATAPI
state machine.
2) After a TEST_UNIT_READY ATAPI command is sent ERR_STAT is getting
set
which is correct. But, when the OS issues another ATAPI command
ERR_STAT is still set. Which is bad since the next expected command
from the OS is REQUEST_SENSE to find out why ERR_STAT is set.

[IA64] domheap: Allocate privregs from domain heap for VTi domain
- Pin privregs down with both dtr/itr so that privregs can be allocated
from the domain heap
- Introduce vmx_vpd_pin()/vmx_vpd_unpin().
The vpd area is pinned down when current. But two functions,
update_vhpi() and alloc_vpd() are exceptions.
We have to pin down the area before PAL call.
- Minor twist context switch not to use unpinned vpd area.
vmx_load_state() needs the vpd area pinned down.
Call it after vmx_load_all_rr()
- Fix vmx_load_all_rr()
vmx_switch_rr7() sets psr.ic = 0 so that clearing psr.ic before calling
vmx_switch_rr7() doesn't make sense.
- Improve vmx_switch_rr7()
It sets psr.ic = 0 after switching to physical mode. But it can be
done at the switching time.
