Make AddressSpaces QOM objects to ensure that they are destroyed when
their owners are finalized and also to get a unique path for debugging
output.

The name arguments were used to distinguish AddresSpaces in debugging
output, but they will represent property names after QOM-ification and
debugging output will show QOM paths. So change them to make them more
concise and also avoid conflicts with other properties.
