This patch:

This patch:

* adds a C-based security policy translation tool to Xen (secpol_xml2bin)
and removes the current Java
security policy translator (Java dependencies).  The C-based tool
integrates into the Xen source tree build
and install (using gnome libxml2 for XML parsing). See install.txt.

* introduces security labels and related tools. Users can now use
semantic-rich label names to put security-tags
on domains. See example.txt, policy.txt.

* moves the security configuration (currently ACM_USE_SECURITY_POLICY)
from xen/Rules.mk
into a separate top-level Security.mk file  (it is needed by the
tools/security and xen/acm).

Both xen/acm and tools/security are built during the Xen build process
only if ACM_USE_SECURITY_POLICY
is not ACM_NULL_POLICY (which is the default setting).
