Fix VMX domains not cleaning up properly, since some page refncts are
not zero. One reason for this is that in function shadow_set_l1e(),
before calling function shadow_update_min_max(), one should call
__shadow_get_sl2e() again, since the sl2 entry may be changed.

The domain structure maintains several shadow mode stats,
such as shadow page counts for l1 & l2, hl2 tables, snapshots,
etc. These counts are not decremented properly when we
free shadow pages. The following patch fixes this problem.
Changed dangerous default parameter values where used to use None instead.
Renamed variables type and ord since these clash with built-in names. Renamed
unused variables to mark them as such. Changed scheduler.py to use *args and
**kwargs rather than the strange non-idiomatic imitation of the same.
Remove the complexity of the config_handlers mechanism in favour of a simple
configure_maxmem method. The config_handlers mechanism was trying to be a
general configuration-registration framework, but that functionality was
unused and confusing.
Replaced the device handling mechanism used by XendDomainInfo. Superficially,
this looks like the resurrection of DevController from controller.py, but the
mechanism is actually very different. Device handling is now stateless inside
xend, relying on the store for state management, reducing DevController
instances to one-shot lifetimes. Dev and its subclasses have gone completely.
The device creation code itself has moved from XendDomainInfo.createDevice into
DevController subclasses, and the previous contents of the subclasses has been
discarded (these subclasses were no longer being called, so all this code was
dead).
XendDomainInfo.getDeviceIds has gone, as it was unused.
XendDomainInfo.delete_device has been subsumed by XendDomainInfo.destroyDevice;
since device handling is now stateless inside xend, the distinction between
device 'deletion' and device 'destruction' is meaningless.
The s-expression describing devices has gone, as this information is no longer
available to xend in the same way, and seems to be unused. If it is required,
it can be reinstated by loading device information from Xen or the store.
Add behaviour to the remove methods to remove the transaction's path itself. This allows us to write Remove(path) to remove the specified path rather than having to slice the path ourselves.
In all cases, move the creation of a new transaction outside of the block
handling exceptions raised inside that transaction. If the creation (start) of
the transaction fails, then t has not been assigned, and in any case no
transaction has been created, so it is wrong to attempt to abort that
(non-existent) transaction.
Replace XendDomainInfo.setStoreChannel with XendDomainInfo.closeStoreChannel.
setStoreChannel was only ever called with channel=None (implying that the
current channel would be closed) so the other code there was superfluous.
Added getVCpuCount to XendDomainInfo and use that and getName, getDomain,
getTargetMemory inside image.py to decouple the latter from the internals of
the former. Move the definition of xc inside image.py to please pylint.
Added getTargetMemory, getSsidref methods to XendDomainInfo, and use these and
getDomain, getName in SrvDomainDir, to decouple the latter from the internals of
the former, in preparation for changes internal to XendDomainInfo.
Added _1,.._5 to dummy-variables, so that we can specify multiple unused
parameters in our code. Removed map and filter from bad-functions - I don't
think that we have any problem with functional programming styles!
Make dom0_enforce_cpus() use vcpu_hotplug rather than directly modifying the sysfs entries.
Directly modifying the sysfs entries causes the xenstore state of
a cpu's availability to be incorrect. Also slightly modify the
dom0-cpus description in the xend-config. Rather than specifying which
dom0 vcpus are to be used, it is now a target of how many vcpus to use
as pinvcpu ops are the preferred method for setting which physical cpu a
vcpu uses. Signed-off-by: Ryan Harper <ryanh@us.ibm.com> Signed-off-by: Christian Limpach <Christian.Limpach@cl.cam.ac.uk>

Grant-refrence allocation pools and tracking tables should be
per interface in netfront, not global. This fixes various
bug reports including Bugzilla #183.
direct_remap_pfn_range() takes a vm_area_struct rather than
an mm_struct. Also it sets VM_RESERVED and VM_IO, just like
generic remap_pfn_range() in mm/memory.c.
Start cleaning up grant tables. gnttab_donate now called
gnttab_transfer, with slightly rationalised interface and
simpler implementation inside Xen. This is a tiny chip off
the tip of a very big iceberg. :-)
add support for ipv6 address in choose_vnc_display function
getting the port from the latest field, not the first one.

The dom destroy path is doing a dom_get on a non-existent domain to
ensure it is non-existent. This changes throws an explicit exception
when xc_domain_getinfo returns an error, instead of triggering an
internal python error. It then handles the exception in dom_get by
returning None, which callers already expect to mean failure.
