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 tool will page out the specified number of pages from the specified
domain. When a paged out page is accessed, Xen will issue a request and
notify the tool over an event channel. The tool will process ther request,
page the page in, and notify Xen.
The current (default) policy tracks the 1024 most recently paged in pages
and will not choose to evict any of those. This is done with the assumption
that if a page is accessed, it is likely to be accessed again soon.
