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()
from these three helper functions. Hence we use req->parent as other
types of request do.

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.

Purpose: To set the priority of the NVMe-oF connection especially
for TCP connection.
For example, the previous example can be:
trtype:TCP adrfam:IPv4 traddr:10.67.110.181 trsvcid:4420
With the change, it could be:
trtype:TCP adrfam:IPv4 traddr:10.67.110.181 trsvcid:4420 priority:2
The priority is optional. We try to change

the opts in spdk_nvme_ctrlr_opts will reflect in every nvme ctrlr,
this is short of flexibility.

Users already have to poll the admin queue, so embed the io_msg
queue polling there to simplify the API.

Disconnecting qpairs from the admin thread during a reset led to an
inevitable race with the data thread. QP related memory is freed during
the disconnect and cannot be touched from the other threads.
The only way to fix this is to force the qpair disconnect onto the
data thread.
This requires a small change in the way that resets are handled for
pcie. Please see the code in reset.c for that change.

Added RPC commands to register/unregister CUSE devices
to NVMe controllers:
- bdev_nvme_cuse_register
- bdev_nvme_cuse_unregister
Additionally two RPC now return CUSE device names:
- bdev_get_bdevs for namespaces
- bdev_nvme_get_controllers for controllers

NVMe character device implementation. This patch adds implementation
of IO producer using CUSE library. It allows to create nvme device
nodes in linux kernel for controller as well as for namespace and
process ioctl requests as usual from linux environment.
Both devices (controller and namespaces) are exposed as character
devices.
To compile NVMe CUSE module use "./configure --with-nvme-cuse".
Names for created CUSE devices can be retrieved using
spdk_nvme_cuse_get_ctrlr_name() and spdk_nvme_cuse_get_ns_name().

This patch allows to send IO requests from external module to the nvme
device.
External module should call nvme_io_msg_ctrlr_start() to start IO message
producer on the controller and enable sending messages.
nvme_io_msg_send() is used to send IO to NVMe driver thread context,
where passed function will be called. Allowing the external module to
issue IO as needed.
NVMe driver users should poll spdk_nvme_io_msg_process() to move forward,
sending IO from external module and process their completions.

This can be useful when trying to perform multipath failover at the
application level. However, the controller must be in the failed state
before calling this function.
