VFIOAddressSpace is a common object used by VFIOContainerBase which is declared in "hw/vfio/vfio-container-base.h". Move the VFIOAddressSpace related services into "container-base.c".
While at it, rename : vfio_get_address_space -> vfio_address_space_get vfio_put_address_space -> vfio_address_space_put to better reflect the namespace these routines belong to.
