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. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>
