My recent changes that introduced batching to queued request
resubmission also introduced a regression that can lead to reordering
requests before submitting them to the drive. This change prevents that.
We wait until inside the internal _nvme_qpair_submit_request function to
check for queued entries to avoid queueing a request that has children.
If a request that has children gets queued, when we process completions
and resubmit the parent, it will result in the children being submitted.
Since we only account for the number of requests we completed in the
last iteration, some of the child requests may be requeued out of order,
or worse, none of the child requests will end up being submitted to the
transport and they will all be queued behind previously queued requests.

Change logout_timeout() not to call spdk_iscsi_conn_construct() but
to move conn->state to EXITING. Then spdk_iscsi_conn_destruct() will
be called by the poller of iSCSI poll group, iscsi_poll_group_poll()

The connection state is mainly for flushing PDUs. ISCSI_CONN_STATE_LOGGED_OUT

Replace ISCSI_CONN_STATE_LOGGED_OUT state by a is_logged_out flag

Previously When the connection is in login processing, flushing PDUs
had been done by tight loop. Login processing will not fill out
send buffers but we can use poller to flush PDUs as same as when the
connection is running iscsi_conn_flush_pdus().
Hence change the check condition to include INVALID state to use
poller in iscsi_conn_flush_pdus().
This change is necessary because the subsequent patches will change
iscsi_conn_flush_pdus() not to flush PDUs when the connection is not
invalid or running.

Session start callbacks have technically two ways
of returning an error code:
a) as the callback return value, e.g. return -1
b) via vhost_session_start_done(int rc)
The former doesn't have any effect as that return value
is not checked anywhere. It's only present because we
wanted to use the same function signature as for the
foreach_session() callbacks. It's going to be cleaned
up in subsequent patches, but before that happens we
have to fix vhost_nvme. With vhost_session_start_done(-1)
called, DPDK will terminate the entire socket connection.

Threads were assigned to sessions inside
vhost_session_send_event() so far, but even the doxygen
comments say that sessions would be assigned to the thread
which called vhost_session_start_done(). Currently, Vhost
uses only vhost_session_send_event() to schedule starting
the session on some thread, so the code ends up working.
We're about to remove vhost_session_send_event(), so move
the thread (poll group) assignment to start_done().
While here, publish the vhost_poll_group struct definition
via vhost_internal.h. As a replacement for
vhost_session_send_event() we would like to use
spdk_thread_send_msg() which a requires a thread object -
one of the struct fields inside vhost_poll_group.
The code for starting a session could look as follows:
pg = vhost_get_poll_group(cpumask);
spdk_thread_send_msg(pg->thread, cb);
...
cb:
// start_pollers
vhost_session_start_done(0);

The type of iovcnt of struct spdk_nvmf_request is uint32_t, and so
change the type of iovpos of struct spdk_nvmf_rdma_request from int
to uint32_t.
iovpos of struct spdk_nvmf_rdma_request is only incremented and
accessed. It is not used for comparison.
So to avoid rerunning CI, this fix is appended to the patch series.

By passing the pointer to struct spdk_nvmf_transport_poll_group
to spdk_nvmf_tcp_req_parse_sgl(), we can remove spdk_nvmf_tcp_req_fill_iovs()
and inline spdk_nvmf_request_get_buffers() into spdk_nvmf_tcp_req_parse_sgl().
Pointers to struct spdk_nvmf_request are used in many lines of
spdk_nvmf_tcp_req_parse_sgl(). Caching and using them simplifies and
improves readability a little for spdk_nvmf_tcp_req_parse_sgl().
We can pass pointer to not struct spdk_nvmf_tcp_transport but struct
spdk_nvmf_transport to spdk_nvmf_tcp_req_parse_sgl().
Ordering the pointer to struct spdk_nvmf_tcp_req first in parameters
of spdk_nvmf_tcp_req_parse_sgl() matches the function name.

Create dpdk_lib_list_to_libs and dpdk_env_linker_args
functions to generate the library filename list and the
linker arguments respectively. Use these functions
internally as well.
These will be useful as part of the Seastar work, where
Seastar pkg-config includes a bunch of the DPDK libraries,
and SPDK needs to just add a few more.

Have each sock implementation free the group_impl itself.
This allows C++ based sock implementations like Seastar
to release the group_impl memory using delete rather
