Use new xstransact.complete to tidy up one other transaction.

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.
This closes bug #290.

Ballooning bugs may still exist (it is unclear) but this is certainly a good
step in the right direction.
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
being overridden by (older) entries in the store.

dependency between those two classes.
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
XendRoot.get_component to pass the singleton instance of XendDomain around.
Both XendRoot.get_component and XendRoot.add_component can go.

free_memory to determine how big to make the domain -- when ballooning down of
dom0 works properly, creating a domain larger than free_memory is possible.

the domain has gone away, then no-one can attach to the pty because Xend will
have cleaned up the entries in the store, so the pty will never become ready to
write. The buffer will never get emptied, so cleanup will never occur. This
leaks ptys, file descriptors, and memory. Simply throw those data away instead.
