  3. virtq: don't allow splitting contigous buffers to multiple descriptors 

    Remove the functionality in prep_transfer_from_raw for splitting a single buffer into multiple descriptors, as it does not have an advantage and complicates the method quite a bit.

  4. virtq: match on individual enums rather than their combinations 

    Match cases made out of combinations cause a lot of code duplication.

  5. virtq: allow providing multiple slices to from-raw transfers 

    This will allow providing transfer data that has an unsized field as a pair of sized and unsized objects, rather than having to create the whole transfer as a dynamically-sized object, as is the case in virtiofs.

  7. fuse: use multi descriptor transfers instead of DSTs 

    Virtio allows a single transfer to be split into multiple buffers. Using this functionality, we can provide the header and the payload in FUSE requests separately. This in turn allows us to avoid the unsafe operations associated with dynamically-sized object creation.
