Without this, xend will not spawn a new device model process after the reboot.

This patch remembers the device model pid across xend restarts and
avoids creating duplicate device model processes.
Also, device models don't inherit socket fds from xend (which are closed
on exec now), which used to prevent xend restarting.

This is needed to support virtual cpu migration, because the host state
initialization is done on every migration, but the rest of the initialization
is done once per vcpu.

If we define "vif" in the config file, image.py will raise error "vmx:
missing vbd configuration". The reason is "vif" is dealt with as a "vbd"
device.
This patch fixes this issue by dealing with "vbd" and "vif " separately,
removing "macaddr" arg and parsing mac address from "vif" instead.
Also, the vbd doesn't have to be a file anymore, but can be a physical
disk partition.

In IBM we have an internal source code scanner called BEAM. We have run
it against Xen and here are some of the results.

many thanks to the help for bug fixes, cleanups, good domU support,
and more from Jun and Xin. I've tested this on a couple different
machines, and made sure the UP build still boots and works. dom0 and
domU smp both work. There's still some cleanups to do, but we'd prefer
to do the last bit in tree. This doesn't update defconfigs just yet.
That'll be a follow-on patch shortly, so for now, you'll have to manually
enable CONFIG_SMP if you'd like to test.

xm list fails if security is enabled because of a single

1) make xenconsoled exit gracefully if xcs dies
2) daemonize xenstored before binding to xenstored socket
3) wait to close stdio in xenstored until we're ready to accept
connections (so that PID=`xenstored --output-pid` doesn't return until
it's ready to accept connections)
4) updates tools/misc/xend for these changes

Mike Wray made this change because xend's callbacks were failing
with EROFS, because a transaction was going on. However, the
solution is to either block callbacks during transactions, or use
a different connection to the store.
We fail ex-transaction activity because it's not clear what the right
behaviour is: it allows deadlock if two people do it, and it implied
your transaction isn't rooted in the right place.
This hack caused the testsuite to fail (obviously), so as a result the
testsuite wasn't run very often. This caused it to bitrot.

It does a number of things:
* It implements the standardized options proposed via my RFC for xm
* It restructures the calling of these functions to be function pointers out
of a dictionary, instead of subclasses found through inspection
* It consolidates all help info, making it easier to see that the help
screen looks consistent across commands. (Per command help isn't yet in
this patch just global help)
* It moves object importing into the functions that require them only,
allowing commands like "xm help" to be runable as non root
* It adds command aliasing to provide backwards compatibility with many
commands (i.e. xm balloon)
* It provides more useful error messages is most fail cases
* It implements a short help by default (which takes < 24 screen lines) as
requested by Mark W at OLS
* It attempts to trap more exceptions than before and provide useful errors
based on them (this requires more testing)
This patch makes no changes to any other elements of xen/xm, and works with
all other objects and libraries as is.
