We don't need to allocate/free tasks on every I/O; we can just
allocate the tasks and buffers once in the initial submit_io() loop.
This also removes the remaining direct DPDK calls from the hotplug

Target enumeration now uses separate poller to receive virtio
response messages. A special virtio_scsi_scan_base struct has
been added to keep track of how many targets we still have to
receive response from.
Making target scan async allows other pollers to run while
bdev_virtio still has to wait for a response.

As destroy_device is used for virtqueue processing *pause* as well as
connection close, the user has no distinction between those.
Consider the following scenario:
rte_vhost: received SET_VRING_BASE message,
calling destroy_device() as usual
user: end-user asks to remove the device (together with socket file),
OK, device is not *in use* - that's NOT the behavior we want
calling rte_vhost_driver_unregister() etc.
Instead of changing new_device/destroy_device callbacks and breaking
the ABI, a set of new functions new_connection/destroy_connection
has been added.

2 locks are executed in 2 places in opposite orders.
Consider the following scenario, threads A and B:
(A)
* fdset_event_dispatch() start
* pfdentry->busy = 1; (lock #1)
* vhost_user_read_cb() start
* vhost_destroy_device() start
(B)
* rte_vhost_driver_unregister() start
* pthread_mutex_lock(&vsocket->conn_mutex); (lock #2)
* fdset_del()
* endless loop, waiting for pfdentry->busy == 0 (lock #1)
(A)
* vhost_destroy_device() end
* pthread_mutex_lock(&vsocket->conn_mutex); (lock #2)
(mutex already locked - deadlock at this point)
Thread B has locked vsocket->conn_mutex and is in while(1)
loop waiting for given fd to change it's busy flag to 0.
Thread A would have to finish vhost_user_read_cb() in order
to set busy flag back to 0, but that can't happen due to
the vsocket->conn_mutex lock.
This patch defers the fdset_del(), so that it's called outside of
vsocket->conn_mutex.
