4185205540 scsi: Remove cb_event. It is no longer necessary.
This is an artifact from a past design. There is no longer
any reason to create an event here - the bdev layer will
correctly queue events and call completions on the correct
thread.

This separates the vhost library from the event

bfd1361714 vhost_scsi: removed deferred tasks
Removed deferred tasks and dynamic memory management in task processing
in vhost_scsi. Each vhost task will now have it's own iovec array

c6745bc2b8 vhost: generalized spdk_vhost_dev struct
Moved controller-related variables from spdk_vhost_scsi_controller to
spdk_vhost_dev. Generalized vhost to operate on non scsi-specific
controller struct.

Now spdk_vhost_scsi_dev contains direct spdk_vhost_dev field instead
of a pointer. This means there is no more allocation/deallocation
on poller start/stop.

19a9871495 scsi: remove spdk_scsi_task::owner_task_ctr
The SCSI library already provides a callback when the task is released
(free_fn), so the user can update their own task counter.

1dbf53eebf vhost: add a library and app for userspace vhost-scsi processing
This patch adds a library, application and test scripts for extending
SPDK to present virtio-scsi controllers to QEMU-based VMs and
process I/O submitted to devices attached to those controllers.
This functionality is dependent on QEMU patches to enable
vhost-scsi in userspace - those patches are currently working their
way through the QEMU mailing list, but temporary patches to enable
this functionality in QEMU will be made available shortly through the
SPDK github repository.
