[Qemu-devel] [PATCH v11 01/12] qmp: delete qemu opts when delete an object

[Yang Hongyang]

When delete an object, we need to delete the associated qemu opts,
otherwise, we can not add another object with the same name using
object_add.
The case happens when we start qemu with:
-object xxx,id=aa
then we delete this object with:
object_del aa
then add the object with:
object_add xxx,id=aa

QEMU will return error with Duplicate ID error.
