I'm not convinced rewriting
LHS = g_malloc(sizeof(*LHS));
to
LHS = g_new(T, 1);
where T is the type of LHS is worth the trouble. The code before the
rewrite is pretty idiomatic. There's no possibility of integer overflow
g_new() could avoid. The types are obviously correct, so the additional
type checking is quite unlikely to catch anything. That leaves the
consistency argument. I'm willing to hear it, but I feel it should be
heard in a patch series that does nothing else.

This hunk is HMP, not QMP.

This is monitor core, not QMP.

Could squash together with PATCH 79 and call the result "monitor: Use
g_new() family of functions".
