memory/hmp: Print owners/parents in "info mtree"
This adds owners/parents (which are the same, just occasionally owner==NULL) printing for memory regions; a new '-o' flag enabled new output. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Message-Id: <20180604032511.6980-1-aik@ozlabs.ru> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
