This will enable asynchronous request handling in a future patch, and it
also removes the need for the RPC handlers to know about request id and
the JSON-RPC rules about notification-only requests.

Vhost scsi tasks aren't complicated enough to have their own files.
Also used spdk_ring instead of rte_membuf for task management.
This patch is a first step towards making vhost task pool
queue-specific, so that it can be single-producer, single-consumer.

Theres no need to have vhost SCSI (and incoming vhost block) structures
available in public API. Generic spdk_vhost_dev might be used to
communicate with backedns. Backends are responsible to check if type of
passed vdev valid.

Implemented vhost abstraction layer in preparations for vhost-blk.
Generalized vhost interface and separated vhost-scsi code.
Code placement:
vhost.h
* vhost_startup() & shutdown()
* public generic controller API
vhost_internal.h
* includes rte_vhost.h from DPDK
* struct spdk_vhost_dev (it has to be inherited by vhost_scsi)
* vhost_dev management
* register/unregister() to be used in new_device()/destroy_device()
* construct/destruct() to be used on permanent creation/destruction.
* reactor core management
vhost_scsi.h
* spdk_vhost_scsi_dev management
* reading VhostScsi section of vhost config file
* creating/removing controllers
* adding/removing devices to controllers
vhost_scsi.c
* virtio scsi logic
* new_device(), destroy_device()

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.

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.
