Change the way we increase poll group reference counts
for round-robin scheduling.
So far we used to increase them whenever someone called
vhost_get_poll_group() and this worked fine for Vhost-Block
which picks a new poll group for each session. Vhost-SCSI,
however, picks only one poll group for all sessions on
a vhost device. This means that some threads will have
multiple Vhost-SCSI pollers but will still appear to the
vhost scheduler as if they had only one.
To fix it, increase poll group refcnt only when sessions
are really being started - in vhost_session_start_done().

Currently vhost_dev_foreach_session() accepts a single
callback function for both iterating through all active
sessions and for signaling the end of iteration (called
last time with vsession param == NULL). Now that the
final signal has completely different semantics and is
called on a specific thread, it makes sense to put it in
a separate function.
While here, remove the one-line description of
spdk_vhost_session_fn typepef. It wasn't helpful anyway.

Historically the callbacks from vhost_dev_foreach_session()
could be called with vdev argument == NULL, which would
mean that device was removed after enqueuing the event
and before consuming it. Now we keep track of pending

allow removing it if there are any unconsumed events,
so the the vdev == NULL checks are redundant. Remove them.

Keeping a global discovery log page was meant to be a time saving
mechanism, but in the current implementation, it doesn't work properly,
and can cause undesirable behavior and potential crashes. There are two
main problems with keeping a global log page.
1. Admin qpairs can be assigned to any SPDK thread. This means that when
multiple initiators connect to the host and request the discovery log,
they can both be running through the spdk_nvmf_ctrlr_get_log_page
function at the same time. In the event that the discovery generation
counter is incremented while these accesses are occurring, it can cause
one or both of the threads to update the log at the same time. This
results in both logs trying to free the old log page (double free) and
set their log as the new one (possible memory leak).
2. The second problem is that each host is supposed to get a unique
discovery log based on the subsystems to which they have access.
Currently the code relies on whether the discovery log page offset in
the request is equal to 0 to determine if it should load a new discovery
log page or use the cached one. This is inherently faulty because it
relies on initiator provided value to determine what information to
provide from the log page. An initiator could easily send a discovery
request with an offset greater than 0 on purpose to procure most of a
log page provided to another host.
Overall, I think it's safest to not cache the log page at all anymore
and rely on a thread local fresh log page each time.

In the past, memory in spdk could have been unregistered in
different chunks than it was registered, so to account
for that the vtophys code used to register each hugepage
(2MB chunk of memory) separately to the VFIO driver. This
really made the code generally simple.
Now that memory in spdk can only be unregistered in the same
chunks it was registered in, we no longer have to register
each hugepage to VFIO separately. We could register the
entire memory region with just a single VFIO ioctl instead,
so that's we'll do now.
This serves as an optimization as we obviously send less
ioctls now, but most importantly it prevents SPDK from
reaching a VFIO registrations limit that was introduced
in Linux 5.1. [1]
The default limit is 65535, which results in SPDK being able to
make only the first 128GB of memory DMA-able. This is most
problematic for vhost where we need to register the memory
of all the VMs.

This is a small performance optimization and an effor to unify I/O
buffer management further among transports.
it is ensured that the request is the first of STAILQ when
nvmf_fc_request_execute() completes successfully.
Hence change TAILQ_REMOVE to STAILQ_REMOVE_HEAD for the case.

This is an effort to unify I/O buffer management further among
transports. RDMA and TCP transport have named pending_queue
pending_data_buf_queue. So FC transport follows RDMA and TCP transport.
The next patch will change pending_data_buf_queue to use STAILQ
instead of TAILQ.

This is a small performance optimization and an effort to unify
I/O buffer management further among transports.
It is ensured that the request is the first of STAILQ when
spdk_nvmf_tcp_send_c2h_data() is called or the case
TCP_REQUEST_STATE_NEED_BUFFER is executed in spdk_nvmf_tcp_req_process().
Hence change TAILQ_REMOVE to STAILQ_REMOVE_HEAD for these two cases.

spdk_bdev_part_construct() must be now called on the
same thread that called spdk_bdev_part_base_construct().
This was always the case so far and I don't see any other
case where thread safety could be useful, so just remove
it. The doxygen doesn't say anything about it either.
Even in GPT case, we create a base directly as a part of
examine and then create part bdevs in the spdk_bdev_read()
completion callback, but that callback will be always
executed on the same thread which issued the read.

Not any different from the test_env version in this patch but it will
be in the upcomiong series as the 2MB tests are added as we will need
to manipulate the size param.
