Grouped a few spdk_vhost_dev struct fields into a new struct spdk_vhost_session. A session will represent the connection between SPDK vhost device (vhost-user slave) and QEMU (vhost-user master). This essentially serves two purposes. The first is to allow multiple simultaneous connections to a single vhost device. Each connection (session) will have access to the same storage, but will use separate virtqueues, separate features and possibly different memory. For Vhost-SCSI, this could be used together with the upcoming SCSI reservations feature. The other purpose is to untie devices from lcores and tie sessions instead. This will potentially allow us to modify the device struct from any thread, meaning we'll be able to get rid of the external events API and simplify a lot of the code that manages vhost - vhost RPC for instance. Device backends themselves would be responsible for propagating all device events to each session, but it could be completely transparent to the upper layers.
