We can merge two loops of req->buffers and req->iov into a single
loop and merge two variables, req->num_buffers and req->iovcnt into
a single variable. For the latter, use req->iovcnt because it is

This patch is the end of the effort to unify buffer allocation
among NVMe-oF transports.
This patch aggregates multiple calls of spdk_nvmf_request_get_buffers()
into a single spdk_nvmf_request_get_buffers_multi().
As a side effect, we can move zeroing req->iovcnt into
spdk_nvmf_request_get_buffers() and spdk_nvmf_request_get_buffers_multi()
and do it in this patch.

This patch is close to the end of the effort to unify buffer allocation
among NVMe-oF transports.
Merge each transport's fill_buffers() into common
spdk_nvmf_request_get_buffers() of the generic NVMe-oF transport.
One noticeable change is to set req->data_from_pool to true not in
each specific transport but in the generic transport.
The next patch will add spdk_nvmf_request_get_multi_buffers() for
multi SGL case of RDMA transport.
This relatively long patch series is a preparation to support
zcopy APIs in NVMe-oF target.

Update transaction length wrt to medata size
Change buffers handling in the case of enabled DIF - add function nvmf_rdma_fill_buffer_with_md_interleave to split SGL into several parts with metadata blocks between them in order to perform RDMA operation with appropriate offsets
Add DIF generation before executing bdev IO operation
Add parsing of DifInsertOrStrip config parameter.
Since there is a limitation on the number of entries in SG list (16), the current approach has a limitation on the max transaction size which depends on the data block size. E.g. if data block size is 512 bytes then the maximum transaction size will be 512 * 16 = 8192 bytes.
In adiition, the size of IO buffer (IOUnitSize conf param) must be aligned to metadata size for better perfromance since metadata is treated as part of this buffer. E.g. if the initiator uses transaction size = 4096, data block size on nvme disk is 512 then IO buffer size should be aligned to (512 + 8) which is 4160. In other case an extra IO buffer will be consumed which will increase the number of entries in SGL and in iov.

It is a very rare thing for a buffer to be split over two memory
regions. In fact, it is only possible in dpdk versions where
--match-allocations is not passed as a startup parameter to dpdk but
dynamic memory allocation is enabled.
By adding a small helper function, we avoid failing an I/O because it
was assigned one of these improperly aligned buffers. Also, we try to
remove the buffer from circulation so that it doesn't get picked up
again by another request.
Also, add a unit test to catch this case.

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.

The first idea was that the caller of spdk_nvmf_request_get_dif_ctx()
should check if the current transport enables DIF insert/strip before
calling spdk_nvmf_request_get_dif_ctx().
But NVMf controller knows if DIF/insert/strip is enabled now by the
previous patch. Hence spdk_nvmf_request_get_dif_ctx() checks if the NVMf
controller enables DIF insert/strip at its head.

The controller shall treat a Keep Alive Timeout in the same manner
as connection loss. If the Keep Alive feature is in use and the
timer expires, then the controller shall:
1, stop processing commands and set the Controller Fatal Status
(CSTS,CFS) bit to '1';
2, terminate the NVMe Transport connection;
3, break the host to controller association;
A timer poller is added to each subsystem to monitor timeout event.

This is shared between all currently valid transports. Just move it up
to the generic structure. This will make implementing more shared
features on top of this a lot easier.
