Closes bug #440.
Change the example configuration files to match. Also change them to use the
XenSource OUI in the MAC addresses. Also change xm-test to match.
Remove the obsolete ipaddr configuration entry, and the backend_mac vif config
option.
Remove the preprocess_vifs function, folding it into the configure_vifs
function, and creating a simple comma_sep_kv_to_dict helper.
Remove the configure_vfr method, as it is unused.

the acceptable connections based upon a regular expression comparison with the
FQDN or the IP address.
Use the hosts-allow facility to restrict access to the relocation socket. This
adds the configuration option xend-relocation-hosts-allow, which takes a
space-separated sequence of regular expressions.
Pass the protocol class instance through to SocketServerConnection, rather than
a new instance of that class. This means that the new instance need not be
passed through SocketListener.acceptConnection.
Make the SocketServerConnection and SocketListener classes start their
corresponding threads and open their sockets (in the case of SocketListener)
automatically. This means that callers do not need to save an instance locally,
just to call run() or listen() on it. This also means that listenTCP and
listenUnix can go -- simply creating a TCPListener or UnixListener instance is
sufficient.

* For setsid to effectively detach a process from the terminal,
the following needs to occur:
fork () Return control to the shell
setsid () New session with no controlling terminal
fork () The session leader (parent) exits and thus
the resulting child process can never regain the terminal
This patch adds the second fork
* The call to self.daemonize(), which now forks, is moved to
run before self.tracing(), as now that it actually disconnects
from the terminal, and thus the prevailing process, the trace
loses the processes created in self.run().

CPUs a domains' vcpus can use. The older 'cpu' config option is
prepended to the list of cpus to use and will keep the behavior of
pinning VCPU0.
The cpus option supports ranges and negation, so:
cpus = "0-3,5,^1" produces -> [0,2,3,5]
The list is circular, so in a domain with the following config:
vcpus = 4
cpus = "0,3,7" # Use any of 0, 3, 7 for this domain.
would see vcpus 0-3 pinned to cpus 0,3,7,0 respectively.
Also, the pin operation is moved before the memory reservation as vcpu
to cpu mapping will be helpful for future NUMA work when trying to
allocate pages close to the physical cpus being used.
An update to the display of cpumap was needed to normalize the cpumap
values to the range of possible cpus.
I've also included some text for the xmdomain.cfg(5) man page.

the permission checking in xenstored.
Default the store permissions to read/write nobody (apart from the privileged
domain). Create a /local node with these permissions, ready for inheriting by
children. In Xend, create a /vm node with these permissions too, for the same
reason, and set the permissions on /local/domain/<domid> and each device
backend path to allow the guest domain to access these paths appropriately.
Added xstransact.{set_permissions,SetPermissions,mkdir,Mkdir,complete} as
support facilities.

Ballooning bugs may still exist (it is unclear) but this is certainly a good

Ignore the memory and maxmem entries in the store for dom0 when restarting.
This means that the value in use at the time becomes the configured target.
This should fix the bug whereby dom0_mem settings on the command line are

Split the XendDomain constructor into two pieces so that XendDomainInfo can
call XendDomain.instance even during the initial startup of XendDomain.
These two together mean that there is no need for the horrendous hack using

Both XendRoot.get_component and XendRoot.add_component can go.
