    vfio: fix custom containers in multiprocess
    
    Currently, the API regarding handling custom (non-default) containers has
    a problem with how it behaves in secondary process. The expected flow for
    using custom containers is to:
    
    1) create a new container using rte_vfio_container_create()
    2) look up IOMMU group with rte_vfio_get_group_num()
    3) bind group to that container using rte_vfio_group_bind()
    4) setup device with rte_vfio_setup_device()
    
    When called from secondary process, rte_vfio_container_create() will check
    if there's space in local VFIO config, and if there is, it will call
    rte_vfio_get_container_fd() which, in secondary process, will call into a
    multiprocess code to request primary process to open container fd, and then
    pass it back to the requester. Primary process does not store this fd
    anywhere, in fact it closes it immediately after responding to the request.
    
    Following that, when we call rte_vfio_group_bind(), we check if the group
    is open locally, and if not, we will call into multiprocess code again, to
    request primary process to open the group fd for us, but since primary did
    not store any information about the new container in step 1, it will store
    the group in local config for default container, and return it to the
    secondary, who will add it to its own config for a different container.
    
    To address these issues, the following changes are made:
    
    1) Clarify meaning of rte_vfio_get_container_fd() to only return the
       default container, and always pick it up from process-local config
    
    2) Avoid calling into multiprocess on rte_vfio_container_create()
    
    3) Avoid calling into multiprocess in group-related code, except when
       dealing with groups associated with default container
    
    As a consequence, SOCKET_REQ_DEFAULT_CONTAINER can be removed and
    consolidated with SOCKET_REQ_CONTAINER, which now only handles the
    default container.
