EBUSY is a legitimate soft failure, due to inability to acquire a
lock, or because RCU work has not been done since a CPU was last
offlined.

This makes the interface consistent with the changes made to the main
interface in 21483:779c0ef9682c.
Also fix some references to "struct xc_interface" which should have
been simply "xc_interface" in tools/xenpaging, and update QEMU_TAG to
pull in the corresponding qemu change.

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.

Exporting cpu on/offline and memory on/offline hotplug interfaces,
so that users can do those (memory/cpu) hotplug actions with
following command line freely:
usage: xen-hptool <command> [args]
xen-hptool command list:\n\n
cpu-online <cpuid> online CPU <cpuid>
cpu-offline <cpuid> offline CPU <cpuid>
mem-online <mfn> online MEMORY <mfn>
mem-offline <mfn> offline MEMORY <mfn>
mem-status <mfn> query Memory status<mfn>
