The issue happens when SPDK RDMA initiator is connected to a remote
target and this target reports rather small (or zero) ICD and we try
to send several SGL descriptors.
Since SGL descriptors are located in ICD, we should check that their
total length fits into ICD. In other case sending such a command
will cause RDMA errors (local length error)

To abort requests whose cb_arg matches, add child abort request greedily.
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
parameter of it.
In each transport, the implementation of qpair_iterate_requests() uses
TAILQ_FOREACH_SAFE() for potential future use cases.

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, RDMA transport dequeues rdma_req from
rqpair->outstanding_reqs after calling nvme_complete_request() for
the request pointed by rdma_req.
Hence while nvme_complete_request() is executed, rqpair->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 rdma_req from rqpair->outstanding_reqs
before calling nvme_request_complete().

The rdma_disconnect call triggers an RDMA_CM_EVENT_DISCONNECTED
message on the target side. The hope is that the target side will
reply with the same message in a reasonable amount of time. If the
target doesn't have that mechanism implemented, print an error message
and continue with the process.

In some situations we may get a completion of RDMA_RECV before
completion of RDMA_SEND and this can lead to a bug described in #1292
To avoid such situations we must complete nvme_request only when
we received both RMDA_RECV and RDMA_SEND completions.
Add a new field to spdk_nvme_rdma_req to store response idx -
it is used to complete nvme request when RDMA_RECV was completed
before RDMA_SEND
Repost RDMA_RECV when both RDMA_SEND and RDMA_RECV are completed
Side changes: change type of spdk_nvme_rdma_req::id to uint16_t,
repack struct nvme_rdma_qpair
Fixes#1292

This API will allow us to simplify the polling mechanism for qpairs on a single
thread. It also will pave the way for doing transport specific aggregation of
qpair polling to increase performance.
The generic implementation is included. The transport specific calls
have yet to be implemented.

If nvme_rdma_qpair_submit_sends() returns -ENOMEM,
nvme_rdma_qpair_process_completions() returns immediately.
In this case, nvme_rdma_qpair_process_completions() does not
poll CQ.
However, nvme_rdma_qpair_process_completions() can poll CQ even
when there is no free slot in SQ.
Hence move nvme_rdma_qpair_submit_sends() and
nvme_rdma_qpair_submit_recvs() after the loop to poll CQ.
nvme_rdma_qpair_submit_sends() and nvme_rdma_qpair_submit_recvs()
output error log and so checking return code of them is not
necessary and is removed in this patch.
This fixes part of the github issue #1271.
