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 adds the option "superpages" to the domain configuration
file. If it is set, the domain is populated using 2M pages.
This code does not support fallback to small pages. If the domain can
not be created with 2M pages, the create will fail.
The patch also includes support for saving and restoring domains with
the superpage flag set. However, if a domain has freed small pages
within its physical page array and then extended the array, the
restore will fill in those freed pages. It will then attempt to
allocate more than its memory limit and will fail. This is
significant because apparently Linux does this during boot, thus a
freshly booted Linux image can not be saved and restored successfully.
