A new API spdk_nvme_ctrlr_cmd_abort_ext() gets cmd_cb_arg as a
parameter, and use it to abort requests whose cb_arg matches cmd_cb_arg.
The caller can set the parameter qpair to NULL if it wants to abort
requests on admin qpair.
Hold ctrlr->ctrlr_lock throughout because abort request is submitted
to admin qpair.
The API is not critical for performance, and so initialize parent
data first.
The API is for a specific qpair, and so hold SQID in the parent,
and it is copied to the children. On the other hand, CID is set
to child when request to abort is found.
Use an new helper function nvme_transport_qpair_iterate_requests()
to add abort request for each outstanding request which has
cmd_cb_arg as its callback context.
The case is possible such that the request to abort is not outstanding
yet but queued. Hence abort queued requests which has cmd_cb_arg
as its callback context too, but it is done only if there is no error
so far.
If only queued requests are aborted and there is no outstanding
request to abort, complete with success synchronously.
If there is no outstanding or queued request to abort, return -ENOENT.
When any abort request is submitted, the difference between success
and failure is only bit 0 of CDW0 according to the NVMe specification.
We cannot the existing helper functions nvme_request_add_child() and
nvme_cb_complete_child() but can use nvme_request_remove_child().
nvme_qpair_submit_request() may use only nvme_request_remove_child()

Use another list dedicated to hold queued requests being aborted
to avoid potential infinite recursive calls.
Add a helper function nvme_qpair_abort_queued_req() to move requests
whose cb_arg matches from qpair->queued_req to qpair->aborted_queued_req.
Then nvme_qpair_resubmit_requests() aborts all requests in
qpair->aborted_queued_req.
The first idea was that nvme_qpair_abort_queued_req() aborts queued
requests directly. However, this caused infinite recursive calls.
Hence separate requesting abort to queued requests and actually
aborting queued requests.
The detail of the infinite recursive calls is as follows:
Some SPDK tool submits the next request from the callback to the completion
of a request in the completion polling loop. For such tool, if the callback
submits a request and then aborts the request immediately, and the request
could not be submitted but queued, it will create infinite recursive calls
by request submit and abort, and it will not be able to get out of
completion polling loop.

Previously free connections had been managed by g_conns_array,
and allocate_conn() gets the lowest free connection. This had worked
almost as LIFO, and the just freed connection had been reused
immediately to the new connection.
Using TAILQ makes management of free connections FIFO, and this will
be more intuitive and simpler, and avoid potential issues due to the
fact that we do not know the state INVALID is the current connection
or the current connection is exited and the new connection is allocated.
This patch includes following updates.
Remove the test condition that the connection ID should be zero.
Connection ID is used as Target Transfer Tag (TTT) and TTT is opaque
number. Hence requiring connection ID to be zero is not meaningful.
iscsi_conn_free() calls free_conn() while holding g_conns_mutex, but
iscsi_conn_construct() does not call free_conn() without holding
g_conns_mutex. Hence add g_conns_mutex to the latter.

This patch only includes the basic framework for batching and the
ability to batch one type of command, copy. Follow-on patches will
add the ability to batch other commands and include an example of
how to do so via the accel perf tool. SW engine support for batching
will also come in a future patch. Documentation will also be coming.
Batching allows the application to submit a list of independent
descriptors to DSA with one single "batch" descriptor. This is beneficial
when the application is in a position to have several operations ready
at once; batching saves the overhead of submitting each one separately.
The way batching works in SPDK is as follows:
1) The app gets a handle to a new batch with spdk_accel_batch_create()
2) The app uses that handle to prepare a command to be included in the
batch. For copy the command is spdk_accel_batch_prep_copy(). The
app many continue to prep commands for the batch up to the max via
calling spdk_accel_batch_get_max()
3) The app then submits the batch with spdk_accel_batch_submit()
4) The callback provided for each command in the batch will be called as
they complete, the callback provided to the batch submit itself will be
called then the entire batch is done.

Iterating all outstanding requests is unique for each transport but
adding child abort is common among transports, and adding child abort
is replaceable by other operations.
Hence add qpair_iterate_requests() function to the function pointer table
of transport, and pass the operation done in the iteration by a

In each transport, the implementation of qpair_iterate_requests() uses

Each request has a callback context as cb_arg, and the callback to
nvme_complete_request() for the completed request may reuse the context
to the new request.
On the other hand, TCP transport dequeues tcp_req from
tqpair->outstanding_reqs after calling nvme_complete_request() for
the request pointe by tcp_req.
Hence while nvme_complete_request() is executed, tqpair->outstanding_reqs
may have two requests which has the same callback context, the
completed request and the new submitted request.
The upcoming patch will search all requests whose cb_arg matches to
abort them. In the above case, the search may find two requests by
mistake.
To avoid such error, move dequeueing tcp_req from tqpair->outstanding_reqs
before calling nvme_request_complete(). One exception is the case that
only nvme_tcp_req_put() is called. For the case remove tcp_req from
tqpair->outstanding_reqs before calling nvme_tcp_req_put().

As is well known, we may also handle the r2t data pdu receving earlier
before calling the cb function of send_cmd due to the outof order execution
of the lower layer uring socket interface.So we need to fix
this issue, otherwise the data of the sending_pdu will be placed with the
wrong data.
And it will cause the issue shown in

When set bdev_auto_examine to false, the bdev layer will only
examine a device if it is in the allowlist. Currently the allowlist
is always empty. Will add api to add bdev to the allowlist in the
future.

Poller should return status > 0 when it did some work
(CPU was used for some time) marking its call as busy
CPU time.
Active pollers should return BUSY status only if they
did any meangful work besides checking some conditions
(e.g. processing requests, do some complicated operations).

nvme_rdma_qpair_submit_recvs is not judged in
nvme_rdma_poll_group_process_completions path.
If we do not clean the recvs_to_post.first we
may get the wrong current_num_recvs when the rc
is non-zero and call it again.
