When setting e.g. 'on_crash=rename-restart' option in domain config
and crashing guest OS running in the domain, the new domain is
restarted with same name as renamed domain.

This patch copies the domain info prior to setting new name and uuid
in the crashed domain info and uses the copied domain info to
construct the restarted domain.

The crashed power state is necessary to allow both core-dumping a
crashed but preserved VM and renaming/restarting a crashed VM.

Time zone info just needs to be calculated in S3 suspend procedure.
However, time_suspend() is also called on AP. That wasteful
get_cmos_time() on AP may break __cpu_die() assumption since
get_cmos_time() can take up to one second. This fix just limits it to
running on the BSP.

Currently there is a pdev_flr() function to do FLR before device
assignment in qemu, but most of devices don't have FLR capability.
What's more, should do FLR before assignment and deassignment for
keeping correct device status. If the device doesn't have FLR
capablility, this patch implemented to enter D3hot and return to D0 to
do FLR. And exposed pdev_flr() in VT-d utils, then it can be invoked
by assignment and deassignment functions.

Have xenstore_read_vncpasswd return -1 when it is unable to read the
passwd from XenStore (and store an empty password). However, don't
exit in such case since it may just mean that the use didn't set a
passwd. If he really did, xend would have given the passwd flag in the
-vnc option, and the empty passwd would make the vnc authentication
reject any password anyway.

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.

Stubdomains (and probably other domain disagregation elements too)
need to be able to tinker with another domain. This adds IS_PRIV_FOR
that extends IS_PRIV by allowing domains to have privileges over a
given "target" domain. XEN_DOMCTL_set_target permits to set this
"target". A new 'target' configuration option makes the domain builder
use it.
