1. platform_op -- used by dom0 kernel to perform actions on the
hardware platform (e.g., MTRR access, microcode update, platform
quirks, ...)
2. domctl -- used by management tools to control a specified domain
3. sysctl -- used by management tools for system-wide actions
Benefits include more sensible factoring of actions to
hypercalls. Also allows tool compatibility to be tracked separately
from the dom0 kernel. The assumption is that it will be easier to
replace libxenctrl, libxenguest and Xen as a matched set if the
dom0 kernel does not need to be replaced too (e.g., because that
would require vendor revalidation).
From here on we hope to maintain dom0 kernel compatibility. This
promise is not extended to tool compatibility beyond the existing
guarantee that compatibility will not be broken within a three-level
stable release [3.0.2, 3.0.3, etc.].

Currently, xenstat_get_node exits with a failure and returns NULL if a
VM is deleted between the time the list of VMs is obtained and the time
it attempts to collect information about the VMs. This patch modifies xenstat
to ignore domains that transition during the call.

to the xentop utility. It also adds the ability to specify the
number of iterations xentop should produce before exiting.
a) xentop -b
will output to stdout.
b) xentop -i <number>
will iterate <number> times and exit (option "n" is already used by
xentop. Hence the choice of "i"). This option can be used for both the
curses and batch modes.

Fix libxenstat to not use multicalls (not permitted, and not

Reject the removal of -Werror from the xentop Makefile.
Reject the #include of xs.h inside xentop -- there is no need for it.

enabled vcpus in a domain. This really isn't an issue anymore with the
changes made to dom0 ops and xm/xend.
But, I provide it because:
- Josh noticed my previous patch called getvcpuinfo twice for each vpcu,
which was completely silly.
- this patch would be useful in the remote chance that domain vpcus are
enabled out of order.

It would be more sensible to represent as a list

Use a collector and new flag for Xen version information, to avoid the
extra hypercall if the caller does not want the information.
Reference the xenstat_handle in the xenstat_node for ease of access
later, and update collectors accordingly.
