This patch eliminate the global variables in libxenctrl (used for
logging and error reporting).
Instead the information which was in the global variables is now in a
new xc_interface* opaque structure, which xc_interface open returns
instead of the raw file descriptor; furthermore, logging is done via
xentoollog.
There are three new parameters to xc_interface_open to control the
logging, but existing callers can just pass "0" for all three to get
the old behaviour.
All libxc callers have been adjusted accordingly.
Also update QEMU_TAG for corresponding qemu change.

This patch exposes the flask_access, flask_avc_cachestats,
flask_avc_hashstats, flask_getavc_threshold, flask_setavc_threshold,
and flask_policyvers functions to user-space. A python wrapper was
created for the flask_access function to facilitate policy based
user-space access control decisions. flask.h was renamed to libflask.h
to remove a naming conflict.

Added the ability to add and delete ocontexts dynamically on a running
system. Two new commands have been added to the xsm hypercall, add
and delete ocontext. Twelve new library functions have been
implemented that use the hypercall commands to label and unlabel
pirqs, PCI devices, I/O ports and memory. The base policy has been
updated so dom0 has the ability to use the hypercall commands by
default. Items added to the list will not be present next time the
system reloads. They will need to be added to the static policy.

Addresses a number of argument handling bugs in the flask_op hypercall
in the XSM:Flask module. Thanks to Rafal Wojtczuk at McAfee for
reporting the issues and Tim Deegan at Citrix for providing an
initial patch.
This patch addresses the following issues:
- bounds checking and validation on input arguments to flask_op
- updated ABI/API, size and cmd are now uint32_t
- updated userspace tools and libraries to account for ABI/API
changes
- implemented all copies using from/to guest, better portability
- implemented upper bounds checking on op->cmd, op->size
- implemented sanity checking on op->size and op->buf
- implemented bit vector for checking from/to usage on op->cmd
