Only tested to localhost. Also add initial code for >1 vcpu guests.

Requires permission check every time event is generated.
Requires generalization of permissions: ask arbitrary number of
parents whether it's OK to tell about node (eg. watching
/dir/subdir/x when /dir is deleted: root permissions will now
determine whether we fire event).
Add test that we don't leak information on whether a file exists
or not.

- Add xenbus driver suspend/resume functions
- Change xenbus irq to not be shared
- Translate store mfn in suspend record to pfn and back
- Make tools re-introduce the domain to the store

separate daemon. In this patch I've included the daemon and a
front-end. I've also have the console code removed from Xend locally
but I wanted to clarify a few things first before submitting that.
Here's how it works:
1) Daemon sits on control channel (via xcs) waiting for console messages
2) Buffers all console data received
3) Publishes the location of a tty that can be used for reading in
/console/<domid>/tty
4) Reads a value from the store to determine what the limit of console
data should be (/console/<domid>/limit) to prevent DoS attacks
Using it is quite simple, just run consoled and use the xc_console
program to connect to the console. It uses syslog for logging.

xenstore instead of control messages.
Note: Because there is no way to set a watch on a non-existent key,
this patch includes a workaround to account for the fact that dom0's
store keys are not initialized by the tools before it boots.

and security policy-versioning and data structures in the xen subtree
(ACM):
* the very generic tools directory name "policy" is changed to
"security" and the included "policy_tool" to "secpol_tool"
* the single constant POLICY_INTERFACE_VERSION is replaced
by ACM_INTERFACE_VERSION; the security policy headers are
versioned independently since the policy can be supplied
at boot time instead of through the hypervisor interface

to support having reading the boot loader config when you're using a
whole disk (eg, file:/root/disk.img,xvda,w) as opposed to just a
partition.
This reads the partition table in the MBR to find the active partition
and then passes that offset down into the filesystem reading code.

frame_and_sectors field in blkif messages, to eliminate the
"magic shifts" in the blkif code.
It also increases the number of bits representing the sector
number within a page, from 3 to 5, to allow page sizes up to
16K (needed for IA64).
Tested to still work on x86.

VMX support was broken. When you boot an unmodified Linux kernel it gets
stuck in the "Calibrating delay" loop. The reason for this is that the
vmx code is repeatedly delivering timer interrupts.
Correcting the MILLISECS() and friends macros to return s_time_t instead
of ULL fixes this problem. The other changes are just to get rid of
redundant code and variables.

- Enforce the number of CPUs dom0 will take. See the new variable
"dom0-cpus" in xend-config.sxp (you will want to set this variable to
1 on SMP systems)
- Balloon out dom0 memory when creating domU, if there is not enough
free memory. The lowest level we will balloon out is configured via
the new variable "dom0-min-mem" in xend-config.sxp
I still have a doubt: where to put the code to enforce dom0-cpus. At
the moment I put it into
python/xen/xend/server/SrvDaemon.py, and hopefully that is resonable
enough. Any comment?
