9d4751a550 lib/nvme: Fix Abort Command Limit to process as 0's based value
SPDK NVMe driver had processed ACL as 1's based value by mistake,
and SPDK NVMe-oF target sets ACL to 0. Hence If NVMe driver connects
to SPDK NVMe-oF transport, spdk_nvme_ctrlr_cmd_abort() always queued
abort request.

Fix this bug to process ACL as 0's based value in
spdk_nvme_ctrlr_cmd_abort(). Besides, initialize ACL explicitly to
0 in spdk_nvmf_ctrlr_identify_ctrlr() for clarification.

55c39cd008 lib/nvmf: Change nvmf_ctrlr_abort_aer() to set completion status of aborted I/O to ABORTED
nvmf_ctrlr_abort_aer() has not been used anywhere, and so we may be
able to remove it, but let's update it to set the completion status
of the aborted AERs to ABORTED for future potential use cases, and
then rename it by nvmf_ctrlr_abort_all_aer() to avoid name conflict
with the next patch.

Setting the completion status to SUCCESS is not good in this case
anyway.

db96437e42 lib/nvmf: Include redirection into spdk_nvmf_request_complete()
Some cases need to redirect spdk_nvmf_request_complete() to the
thread pointed by qpair->group->thread. Abort command will be
included such cases but abort command is executed in the different
file ctrlr_bdev.c. For the convenience, change spdk_nvmf_request_complete()
to include the redirection and extract the core operation of
spdk_nvmf_request_complete() into a private function
_nvmf_request_complete(). In ctrlr.c, call _nvmf_request_complete()
for non-redirected cases.

Besides, locate the definition of _nvmf_request_complete() under the
definition of  spdk_nvmf_request_complete() in a file to trick the format
check tool to avoid false positive, and fix a spell error together.

9d39be44c5 nvmf/ctrlr: remove assert for qpair state.
Historically, we have immediately called the qpair
fini function directly from _spdk_nvmf_qpair_destroy.

However, to fix a race with initiators where we can get
a duplicate QID from the initiator, we will have to clear
the QID bit before calling qpair_fini. Clearing the QID bit
must be done on the controller thread, so we have to pass at
least two messages between calling _spdk_nvmf_qpair_destroy
and qpair_fini. This leaves a gap where we can poll the poll group
and reap completions for the qpair before we call qpair_fini and drain
all of the requests related with the qpair.

1c5444d623 nvmf: Queue Connect command when subsystem is paused
Currently SPDK rejects Connect command when subsystem is not active.
This change allows to queue Connect command and execute it when
the subsystem goes back to active state. To queue the command we
should know subsystem_poll_group, in current implementation
this poll_group is known only when controller is already created.
To get the poll_group for Connect command we can retrive subsystem
subnqn, find subsystem and get poll_group by subsystem->id.

Increment subsystem_poll_group->io_outstanding even for Connect
cmd in order to prevent subsystem change state during the
connection process. Update spdk_nvmf_request_complete -
decrement io_outstanding for Connect cmd.

Fixes #1256

f0ca01e102 lib/nvmf: properly validate fuse command fields.
The fuse command value is a two byte value, but we were only checking to
see if the fuse value was equal to SPDK_NVME_CMD_FUSE_FIRST or
SPDK_NVME_CMD_FUSE_SECOND in spdk_nvmf_ctrlr_process_io_fused_cmd. If a
haywire initiator sent a command with a fused value equal to
SPDK_NVME_CMD_FUSE_MASK, that would result in us skipping all checks and
dereferencing a null pointer in
spdk_nvmf_bdev_ctrlr_compare_and_write_cmd.

To fix this, add an extra condition to validate the cuse field.

4dba507224 nvmf/tcp: Simplify qpair resource initialization
The resources allocated to a queue pair do not need to be directly
correlated to the queue size requested by the initiator in NVMe-oF, as
long as enough resources are present. The RDMA transport, for instance,
does complex pooling of the resources behind the scenes when using a
shared receive queue.

Simplify the resource allocation for a TCP qpair to just always allocate
the max allowed queue size right away. This is a configurable parameter,
so system administrators can adjust for their needs. The initiator may
then request a queue size less than or equal to that, which will only be
enforced by queue depth counting and not impact the actual number of
resources allocated on the target.

This change relies on the MaxC2HSize being equal to the Maximum Data
Transfer Size (MDTS) reported. That is the default configuration, but
MDTS is configurable. Changing the MDTS with this patch to a value
larger than 128k will cause the target to break. This is addressed in
the next patch in this series.

3fa2205647 lib/nvmf: custom admin cmd handler
This commit provides the capability to install a
    custom admin command handler for NVMF.
    It can be used to implement or replace NVMe admin commands that
    are currently not handled by the NVMF subsystem.

    The handler implementation is pretty generic and the handler function
    has to figure out what to do with the command based on the bdevs
    that are configured for the subsystem.
    In cases where admin commands need to be forwarded to an NVMe bdev,
    the commit provides functions that allow access to the underlying bdev.

    There is an example handler in lib/nvmf/custom_cmd_hdlr.c.
