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.
