Seraphime Kirkovski f49fa658b5 tools:misc:xenlockprof: fix possible format string overflow
GCC7 complains about a possible overflow/truncation in xenlockprof.

xenlockprof.c: In function ‘main’:
xenlockprof.c:100:53: error: ‘%s’ directive writing up to 39 bytes into a
                         region of size between 17 and 37 [-Werror=format-overflow=]
             sprintf(name, "unknown type(%d) %d lock %s", data[j].type,
                                                     ^~
xenlockprof.c:100:13: note: ‘sprintf’ output between 24 and 83 bytes
                                             into a destination of size 60
             sprintf(name, "unknown type(%d) %d lock %s", data[j].type,
             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                     data[j].idx, data[j].name);
                     ~~~~~~~~~~~~~~~~~~~~~~~~~~

This increases the size of name to 100. Not the most scalable solution,
but certainly the "cheapest", as it doesn't add dependencies for
asprintf.

Ian Campbell 4f42a4e74f libxc: simplify lock profiling API
Current function has heavily overloaded semantics for the various
arguments. Separate out into more specific functions.

Keir Fraser 5cc436c1d2 libxc: eliminate static variables, use xentoollog; API 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.
