32d7c91cbc bdev: add spdk_bdev_queue_io_wait()
This function is intended to be used when an spdk_bdev
I/O operation (such as spdk_bdev_write or spdk_bdev_write_blocks)
fails due to spdk_bdev_io buffer exhaustion.  The caller
can queue an spdk_bdev_io_wait structure on the calling thread
which will be invoked when an spdk_bdev_io buffer is available.

While here, turn off error messages in bdev.c related to
spdk_bdev_io pool exhaustion, since we now have an API designed
to gracefully recover from it.

Also modify bdevperf as an example of how to use this new API.

8c6bd59704 virtio: remove unnecessary if
This `if` came from the original DPDK virtio PMD.
Generally, we do not want to trigger cache coherency
updates if we don't have to, but in this particular
case we know we always do.

If there were no changes to the avail index, there
would be no requests started and the function would
return much earlier.

69679c8033 thread: assert if io_device_unregister cannot find device
The bdev iscsi initiator had a bug which resulted in
an io_device getting unregistered twice.  An error message
got printed but it didn't immediately result in any kind
of failure detected by any tests.  Really this should be
considered a fatal error, so add an assert() so it's found
more readily should these kinds of bugs occur again in the
future.

2255533973 bdev: remove shared_resource from TAILQ before putting io channel
Normally, the put_io_channel is deferred - but for unit tests
messages are called inline and not as events.  This results
in spdk_bdev_mgmt_channel_destroy() complaining that
the shared_resource list isn't empty.

So just remove it from the TAILQ before putting the io_channel -
that's more correct anyways.

9abd8becc5 Avoid scheduling removal of the same bdev descriptor multiple times.
Deferred descriptor removal invocation under bdev_unregister() does
not account for the possibility of bdev_unregister being entered
multiple times for the same bdev (which is possible thanks to multiple
paths to unregistration - consider bdev hotremove callback and
_spdk_bdev_finish_unregister_bdevs_iter iterator - being present).
Therefore, currently nothing prevents _remove_notify for the same bdev
descriptor from being scheduled multiple times.

This commit adds boolean remove_scheduled field to struct spdk_bdev_desc.
The value is set when remove_notify for the descriptor is being
scheduled for the first time, and checked on subsequent attempts.

ed6827edbf bdev: prepopulate per-thread bdev_io cache
This helps prevent starvation in the case where a thread
is started but remains idle, while other threads consume
all of the spdk_bdev_io buffers in the global pool.

This starvation issue is fairly theoretical at this point,
but future patches will be adding the ability for callers
to be notified when an spdk_bdev_io becomes available if
the pool is exhausted.  We will add tests to stress
pool exhaustion at which point this patch will become
much more important.

While here, increase the minimum bdev_io_pool_size to
account for the mgmt_ch getting destroyed and then
immediately created again on the master core.  In this
case there is a window where both channels exist at
once - the one being destroyed won't free its cached
spdk_bdev_ios until the deferred spdk_put_io_channel
event executes.

4f47c066c9 iscsi initiator: remove the deleted variable.
I do not think that this variable is needed.
The rpc system will be always executed in the first
call, so there is no sync issue, add a deleted variable
and put the free in the loop sounds not very clear.

For the ASAN issue (use req after free), I think
that the correct solution is that: we should store
the context first instead of defer the free of req.

eb387189c2 nvmf: don't change NN while ctrlrs exist
This was partially fixed in commit 1e481d0438e6 ("nvmf: Do not allow NN
to change while connections present"), but we did not handle the case
where the user asked to add a NS with a NSID outside the current NN.

This patch reworks the logic (again) to be more straightforward and
hopefully more obviously correct.

Some confusion between max_allowed_nsid and max_nsid is also clarified;
if max_allowed_nsid is set, then max_nsid == max_allowed_nsid at all
times, so we don't need the extra logic when calculating NN in
spdk_nvmf_ctrlr_identify_ctrlr().

e30535fecf thread: add spdk_thread_get_count()
This will return the number of currently allocated threads.

Modify the bdev_io caching code to use this new API since these
caches are really per-thread, not per-core.  SPDK does not support
dynamic threading yet, but once it does, we will want callers to be
using functions from the thread API - not counting the number of cores
allocated to the application.

spdk_env_get_core_count may still be useful as a helper function, so
it is still kept and not deprecated.  For example, app.c uses it to
print the number of cores allocated to the application.  bdevperf should
eventually be modified to use spdk_thread_get_count, but holding off on
that for now until spdk_event_allocate() uses threads instead of a reactor
lcore to specify where the event should be executed.
