memory: add ref/unref calls

Enterprise / Virtualization / QEMU - Paolo Bonzini [redhat.com] - 4 July 2013 10:42 UTC

Add ref/unref calls at the following places:

- places where memory regions are stashed by a listener and used outside the BQL (including in Xen or KVM).

- memory_region_find callsites

- creation of aliases and containers (only the aliased/contained region gets a reference to avoid loops)

- around calls to del_subregion/add_subregion, where the region could disappear after the first call
