symlinks get removed and relinked to base implementation. Make these non
c-obj's to preserve sparse tree links.

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
