The OCaml xenstored supports the XS_RESTRICT operation, which
deprivileges a dom0 xenstore connection so it can only affect one
domain's entries. Add the relevant definitions to the C libraries
so that callers can use it.

I don't think protocol specific data really belongs in this header
but since it is already there and we seem to be stuck with it let's at
least make the users explicit lest people get caught out by future new
fields moving the pad field around.
This is the Xen portion of this change. The kernel portion will be
sent separately. There is no dependency between the two.

This is the patch to fix pyGrub default value when it's being set out of
range. This patch makes the quiet and interactive mode select the same
default image when the default value for boot entry is out of range,
i.e. when the guest is having wrong configuration in it's boot loader
(like 3 entries with default mistakenly set to 10 etc).
When the boot entry number is being set out of range it falls back to 0
(first entry of boot loader).

On one of my boxes, the xenstore-write setting dom0's name starts
before xenstored is actually ready to handle the connection properly,
resulting in the name set failing. Wait for xenstored to be up and
responding to reads before continuing, timing out after 30 seconds.

add a command "domstate" to get the state of Vms, which may have one state of
{'shutoff', 'idle','shutdown','running','crashed','paused' or 'paused by
admin"}.
For case of pause, I distinguish it into two conditions. One is "paused" the
other is "paused by admin".
"pasued by admin" means that users pause a domain voluntary by "xm paused
VM" or " API"

Oxenstored should not try to create the evtchn device, as it:
* creates the wrong name (/dev/xen/eventchn rather than evtchn)
* uses a hard-coded minor number, even though this dynamically
depends on what other misc devices are in the kernel
Remove all this code and just rely on the system to create the device.

at the moment libxl_wait_for_device_model waits on a xenstore watch
before checking the current value of the xenstore node, that might
contain already the value the function was looking for.
This patch changes libxl_wait_for_device_model so that it checks the
value of the xenstore node first, then waits for the watch.
xenstore watch automatically fire one time when you install them for
this exact same purpose, so the previous code is not wrong, but this
version is clearer.

Fix the xencommons init script chkconfig configuration since the
priority was missing here and chkconfig was complaining about invalid
chkconfig script so I added both start and stop priorities to the
chkconfig line and it was working fine, the script was successfully
added to chkconfig when using `chkconfig --add xencommons` and
management using the chkconfig utility was now possible.
Tested on RHEL-5 Server with Xen-4.1-unstable installed, running on
PVops kernel 2.6.32.15 and it was working fine.

In XendDomainInfo.py device_create function, when device type is
"vif", it has a paragraph to check the validity of "mac"
address. Before checking validity, device_add has been done. But after
checking validity, if the mac address is invlid, it raises VmError and
exits directly without doing clean work like removing the device item
from config info. This will cause that the incorrect mac address is
saved into VM Config file and VM fails to restart. If check "mac"
validity before doing device_add, there will be no problem.

used as a replacement of xm in xendomains:
- dryrun and quiet, long options to xl create;
- l, option to xl list.
printf_info is now used to print the configuration of the running VMs so
the output has been reformatted to be similar to the output of xm list -l.
There is still one command used in xendomains that is not implemented in
xl and not covered by this patch: xm shutdown. However a patch has been
sent to the list in the past and we are expecting a new version of it
soon.

If a command hold domains_lock, "xm list" would hang for waiting for
the lock. Such as creating many VMs at a script (such as 20), command
of "xm list" could hang for long time(10 mins). I think domains_lock
here only protect update(). So, we shouldn't do update before command
of "list" really get this lock, but xm do need show the domain's
information quickly. In this patch, if command couldn't get the
domains_lock after 20 times trying, "xm list" would show the
information of VMs without update().
