mce: Enhance the vmce injection check logic
Currently we will not inject vMCE if guest has different mca control
register setup.
This is not enough, we need consider more. If guest has different
family/model, we should not inject guest, because the MCA error code
include model specific information. If guest has not enabled MCE
(i.e. CR4.X86_CR4_MCE is clear), we should not inject vMCE.
One thing need notice. In the memory error handler, we didn't kill the
guest if vMCE is not ready, instead, we will simply ignore the
vMCE. In native, system will reboot if MCE in CR4 is not enabled. We
need contain guest access to the broken memory through eithe software
or hardware method.

xl: init scripts (v2)
Now the init script is called xencommons and, as the name suggests, it
is a common script between xl and xend because it is used to start
xenconsoled, xenstored and xenbackendd and the initialization of these
three daemons has been removed from xend. The global
xen_toolstack=xl/xend variable has been removed. Regarding the
network setup, I made the vif scripts follow the same pattern as the
other scripts in xen-backend: a new script called vif-setup is
executed unconditionally. vif-setup is going to do the right thing
depending on the value of the environmental variable "script" (same
technique used before), defaulting to vif-bridge. In the common
scenario the toolstack doesn't need to set the variable "script"
because vif-bridge is going to be called anyway. There is no global
network script to setup the network bridges with xl, so if you are
using xl without xend, you need to manually configure the bridges
using your distro network setup, or, if you are lazy, you can just add
something like:
/etc/xen/scripts/network-bridge start
to your rc.local.

Add xl init scripts
this patch adds an init script for xl, so that it can be used without
xend installed on the system. In cases in which both toolstacks are
present, only one init script will be run, dependening on the value of
xen_toolstack in /etc/sysconfig/xen_toolstack. Please note that a
correct value of xen_toolstack (either xl or xend), is required now.
The network script and the vif script to be used with xl can be
specified in /etc/sysconfig/xenlightdaemons. Xl sets the vif script
to xl-vif-script by default, that reads /etc/sysconfig/xenlightdaemons
and calls the vif script set there. A port to a debian system should
be straightforward, just replacing /etc/sysconfig with /etc/default
everywhere.

Add a safety valve to the HVM RTC model for big time jumps
If xen's time leaps forward by a large amount, the RTC will try to
model a tick for every second that it thinks has passed. This can
livelock a CPU with a series of timer requests each of which fires
immediately and requests the next one.
This patch treats a delay of more than a day between ticks as a
special case, abandoning the attempt to catch up. That should be good
enough to avoid livelock but doesn't fix the underlying time problem.
