Merge remote-tracking branch 'remotes/gkurz/tags/for-upstream' into staging

- Aneesh no longer listed in MAINTAINERS,
- deprecation of the handle backend,
- improved error reporting, especially when the local backend fails to
  open the VirtFS root,
- virtio-9p-test to behave more like a real virtio guest driver: set
  DRIVER_OK when ready to use the device and process the used ring
  for completed requests,
- cosmetic fixes (mostly coding style related).

  tests: virtio-9p: set DRIVER_OK before using the device
  tests: virtio-9p: fix ISR dependence
  9pfs: make pdu_marshal() and pdu_unmarshal() static functions
  9pfs: fix error path in pdu_submit()
  9pfs: fix type in *_parse_opts declarations
  9pfs: handle: fix type definition
  9pfs: fix some type definitions
