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.

Renamed XendDomainInfo.getTargetMemory to getMemoryTarget, for consistency with
XendDomainInfo.setMemoryTarget.

Signed-off-by: Ewan Mellor <ewan@xensource.com>

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.
