acm: Changes to XML schema of the policy

This patch changes the XML schema of the ACM policy to require a
version and that every conflict set have a name. Every VM label must
have one Chinese Wall Type and every resource label one Simple Type
Enforcement Type. As a consequence of this some example policies
needed to be changed. Also not offering that many configuration
options for compiling xen anymore to make things simpler.
