This closes races between concurrent spdk_bdev_module_claim_bdev()
and/or spdk_bdev_module_release_bdev() calls affecting the same bdev by
holding bdev->internal.spinlock while claiming and releasing a bdev. It
also closes a potential TOCTOU bug in that optimizing compilers probably
already eliminate in bdev_finish_unregister_bdevs_iter() and documents
that bdev->internal.claim_module is protected by
bdev->internal.spinlock.
This can be removed when the bdev_register_examine_thread deprecation
is removed.

Since bdev_examine() can happen on any thread and it happens without any
other lock being held on the spdk_bdev_module, it is possible for
multiple threads to try to simultaneously increment
module->internal.action_in_progress. Decrements may also race.
This commit adds bdev_module->internal.spinlock and holds it while
modifying module->internal.action_in_progress.
This can be removed when the bdev_register_examine_thread deprecation
is removed.

This introduces a deprecation for calling spdk_bdev_register() and
spdk_bdev_examine() on a thread other than the app thread. The
deprecation period starts in SPDK 23.01 and removal is expected in SPDK
23.05.
The intent of this deprecation is to ensure that bdev modules'
examine_config() and examine_disk() callbacks are only ever called on
the app thread. This largely a formalization of what has long happened
due to the RPC poller running on the first thread started by
spdk_app_start().

Commit 41f59559e added code to skip adding EXITING connections
to the new poll group in the full_feature_migrate message
callback. The problem is that since the connection is in
EXITING state and is not in a poll group, it will never move
to EXITED state, nor get removed from g_active_conns, and
hence will block the iscsi subsystem from being able to
shutdown.
So instead, assert that the connection is not in EXITED
state. If it is in EXITING state, we will add it to the
poll group, and then when the poll group is next polled,
it will destroy the connection, moving it to EXITED
state and removing it from the g_active_conns STAILQ.
This fix is related to issue #2416.

Many parts of the blobstore.c seem to have gone with the assumption that
blob creation, deletion, etc. all happen on the md thread. This
assumption would allow modification of the bs->used_md_pages and
bs->used_clusters bit arrays without holding a lock. Placing
"assert(spdk_get_thread() == bs->md_thread)" in bs_claim_md_page() and
bs_claim_cluster() show that each of these functions are called on other
threads due writes to thin provisioned volumes.
This problem was first seen in the wild with this failed assertion:
bs_claim_md_page: Assertion
`spdk_bit_array_get(bs->used_md_pages, page) == false' failed.
This commit adds "assert(spdk_spin_held(&bs->used_lock))" in those
places where bs->used_md_pages and bs->used_lock are modified, then
holds bs->used_lock in the places needed to satisfy these assertions.

The idea behind "iobuf" is to have a single place for allocating data
buffers across different libraries. That way, each library won't need
to allocate its own mempools, therefore decreasing the memory footprint
of the whole application.
There are two reasons for putting these kind of functions in the thread
library. Firstly, the code is pretty small, so it doesn't make sense to
create a new library. Secondly, it relies on the IO channel abstraction,
so users will need to pull in the thread library anyway.
It's very much inspired by the way bdev layer handles data buffers (much
of the code was directly copied over). There are two global mempools,
one for small and one for large buffers, and per-thread queues that hold
requests waiting for a buffer. The main difference is that we also need
to track which module requested a buffer in order to allow users to
iterate over its pending requests.
The usage is fairly simple:
```
/* Embed spdk_iobuf_channel into an existing IO channel */
struct foo_channel {
...
struct spdk_iobuf_channel iobuf;
};
/* Embed spdk_iobuf_entry into objects that will request buffers */
struct foo_object {
...
struct spdk_iobuf_entry entry;
};
/* Register the module as iobuf user */
spdk_iobuf_register_module("foo");
/* Initialize iobuf channel in foo_channel's create cb */
spdk_iobuf_channel_init(&foo_channel->iobuf, "foo", 0, 0);
/* Finally, request a buffer... */
buf = spdk_iobuf_get(&foo_channel->iobuf, length,
&foo_objet.entry, buf_get_cb);
...
/* ...and release it */
spdk_iobuf_put(&foo_channel->iobuf, buf, length);
```

which are created though bdev_rbd_register_cluster),
error message "the *ERROR*: msg could not be allocated error message"

We found the issue from the limited msg_mempool_size size, which is hardcoded

The kernel vfio_pci driver module introduced vf_token checking
mechanism since kernel version 5.7, and has been supported by
DPDK. So add support for it to deal with the scenario of VF.

The current code for setting/getting coalescing setting only works with
vhost-user devices, while users can create virtio-blk devices with
non-vhost-user transport. Calling spdk_vhost_(set|get)coalescing() on
such device results in a segfault.
So, spdk_vhost_dev_backend interface is extended with methods to
set / get coalescing parameters. In the following patch, the virtio_blk
interface will be also extended with similar callbacks allowing us to
pipe coalescing settings to the appropriate transport.

Both the length of a request and the number of ranges to copy are
controlled by the user, so we should check them and return an error
instead of asserting that they're correct.

srandomdev is *only* used to emulate arc4random, so only
bother defining it on Linux when it's needed. This avoids
unused errors on newer distros packaging glibc versions

This patch fixes issue # 2809, by changing the max
completions processed per poll. A new parameter called
IDXD_MAX_COMPLETIONS is used to set maximum completions
processed per poll to 128 because we observed performance
degradation on a system with 16 NVMe SSDs at a queue depth
of 64 per SSD. When using DSA to compute the data digest,
the target application can issue upto 1024(16x64) request
to compute data digest concurrently to DSA. Limiting the
maximum completions processed per poll to 32 using
DESC_PER_BATCH cause up to 43% IOPS degradation.
Use IDXD_MAX_COMPLETIONS to control the number of
completions proccessed per poll in spdk_idxd_process_event
based on your workload. For example, if your application
is issuing 1000s of concurrent request to DSA you might
want to set IDXD_MAX_COMPLETIONS to a value higher than
128.
