Is there any reason (other than being coding style) in using qemu_free()
instead of free()? As per qem-malloc.c qemu_free() is nothing but free().
The reason I am asking is.. tracking string allocs become tricky
if some of them were defined using qemu_alloc() and others are allocated through
sprintf().
