Does this mean we need to duplicate the type name for each allocation?
struct foo *f;
...
f = qemu_malloc(sizeof(*f));
Becomes:
struct foo *f;
...
f = QEMU_NEW(struct foo);
If you ever change the name of the type you have to search-replace
these instances. The idomatic C way works well, I don't see a reason
to use QEMU_NEW().
It works as long as you don't make any mistakes:
f = qemu_malloc(sizeof(*g));
f = qemu_malloc(sizeof(f));
qemu_malloc() returns a void pointer, these are poisonous.
