vring notification mechanism is transport-specific. At present, vhost
dataplane code in `lib/vhost/vhost.c` triggers guest notifications with
`eventfd_write()` system call. But this is an AF_UNIX specific
notification mechanism. This patch replaces `eventfd_write()` with the
existing generic `rte_vhost_vring_call()` function that is part of
DPDK's librte_vhost public API.
`rte_vhost_vring_call()` takes a vring_idx as an argument to associate
the `struct spdk_vhost_virtqueue` instance with the relevant `struct
vhost_virtqueue` instance. We introduce a new `vring_idx` field in
`struct spdk_vhost_virtqueue` to enable this association. This field is
initialized in `start_device()`. In addition, a stub for
`rte_vhost_vring_call()` is added in the vhost unit test file.
SPDK's internal `rte_vhost` copy will not be updated in order to support
the virtio-vhost-user transport. However, an `rte_vhost_vring_call()`
function is introduced in SPDK's `rte_vhost` in order to have a solid
API. This function is just a wrapper of `eventfd_write()`.

We flush a cache buffer once it's filled. When the write
for that cache buffer has completed, we look to see if
there's more data to flush. Currently if there's *any*
more data to flush, we will flush it, even if it's not
a full buffer.
That can hurt performance though. Ideally we only want
to flush a partial buffer if there's been an explicit
sync operation that requires that partial buffer to be
flushed. Otherwise we will end up writing the partial
buffer to disk, and then come back and write that data
again later when the buffer is full.
Add a new unit test to test for this condition. This
patch breaks one of the existing unit tests which was
designed specifically around a RocksDB failure condition.
Change that file_length unit test to now write exactly
one CACHE_BUFFER, which still tests the general logic
making sure that we don't confuse the amount of data
flushed with the value written to the file's length
xattr.

Data can get implicitly flushed as cache buffers are filled. But
the length xattr is only written in response to a sync or close
operation. So we cannot just look at the amount of data flushed,
and ignore the sync operation if all of the data written has been
flushed - we still need to write the length xattr.
This also adds a unit test which reproduces the original problem.

For the latest TLC NAND, one write buffer unit (rwb batch)
needs to be spread over three PUs instead of being allocated
to a single PU for better sequential read performance
since the optimal write size(ws_opt) of 3D TLC NAND is
3 times bigger than the optimal read size(rs_opt).
I added num_interleave_units in 'struct spdk_ftl_conf'
to configure the number of interleaving units per ws_opt.
If num_interleave_units is set as 1, the whole of the ws_opt
blocks are placed sequentially around each PU.
If num_interleave_units is set as N, the 1/N of the ws_opt
blocks are staggered. So consecutively numbered blocks
are separated by ws_opt / num_interleave_units.
The sequential read performance is improved from 1.9GiB/s
up to 2.97GiB/S with this patch on our system. No performance
degradation is observed on sequential writes or
4KB random reads/writes.

_dif_sgl. The name sgl has been already adopted widely in SPDK.
