This breaks make check on F20:

"""
/home/lcapitulino/work/src/upstream/qmp-unstable/tests/test-qmp-event.c: In function ‘main’:
/home/lcapitulino/work/src/upstream/qmp-unstable/tests/test-qmp-event.c:254:5: error: ‘g_thread_init’ is deprecated (declared at /usr/include/glib-2.0/glib/deprecated/gthread.h:260) [-Werror=deprecated-declarations]
     g_thread_init(NULL);
     ^

"""

I think the best way to fix this is to make util/osdep.c:thread_init()
public (maybe by moving it to include/glib-compat.h) and use that instead.
Also, note that thread_init()'s body is duplicated in a few other places,
so maybe those places should call it too.

You may want to do this in a different series, then I can skip this patch
and apply the rest of the series.
