When regular lvols are created, their size is rounded up to the next
cluster boundary. This is not acceptable for esnap clones as this means
that the clone may be silently grown larger than external snapshot. This
can cause a variety of problems for the consumer of an esnap clone lvol.
While the better long-term solution is to allow lvol sizes to fall on
any block boundary, the implementation of that needs to be suprisingly
complex to support creation and deletion of snapshots and clones of
esnap clones, inflation, and backward compatibility.
For now, it is best to put in a restriction on the esnap clone size
during creation so as to not hit problems long after creation. Since
lvols are generally expected to be large relative to the cluster size,
it is somewhat unlikely that this restriction will be a significant
limitation.

A host will consider a QID as reusable once it disconnects
from the target. But our target does not immediately
free the QID's bit from the ctrlr->qpair_mask - it waits
until after a message is sent to the ctrlr's thread.
So this opens up a small window where the host makes
a valid connection with a recently free QID, but the
target rejects it.
When this happens, we will now start a 100us poller, and
recheck again. This will give those messages time to
execute in this case, and avoid unnecessarily rejecting
the CONNECT command.
Tested with local patch that injects 10us delay before
clearing bit in qpair_mask, along with fused_ordering
test that allocates and frees qpair in quick succession.
Also tested with unit tests added in this patch.

We need to be checking whether the specified qid
is too large or not - the current test says it is
doing that in the comments but is really just
checking the duplicate QID path (which following
test already covers).

The 2 MiB minimum may be not reasonable for some users, so it is changed
to 4 KiB to allow wider range of possible values.
The new default is introduced to keep backward compatibility (2 MiB).

There's no reason to check the OS to decide whether to build some unit
tests if we can rely on the configure parameters. For instance, on
FreeBSD, RDMA unit tests can be built and run successfully, while vhost
is always disabled in configure.

When an esnap clone blob's external snapshot arrives after the blob is
opened, it can now be hot-added to the blob. Presumably the new device
replaces a place-holder device that did not really atteempt IO.

To avoid races that lead to use-after-free errors during esnap device
hot add/remove, we need a way to ensure that the destroy callback does
not free a bs_dev until all consumers are done.
This adds reference counting to the create_channel() and
destroy_channel() callbacks. The reference couunt is initialized to 1
and is decremented by destroy(). The destroy() and destroy_channel()
callbacks are updated to free the bs_dev only when the reference count
drops to 0.

As the blobstore is being unlaoded, async esnap channel destructions may
be in flight. In such a case, spdk_bs_unload() needs to defer the unload
of the blobstore until channel destructions are complete.
The following commands lead to the illustrated states.
bdev_malloc_create -b malloc0
bdev_lvol_clone_bdev lvs1 malloc0 eclone
.---------. .--------.
| malloc0 |<--| eclone |
`---------' `--------'
bdev_lvol_snapshot lvs1/eclone snap
.---------. .------. .--------.
| malloc0 |<--| snap |<--| eclone |
`---------' `------' `--------'
bdev_lvol_clone lvs1/snap eclone
.--------.
,-| eclone |
.---------. .------.<-' `--------'
| malloc0 |<--| snap |
`---------' `------'<-. .-------.
`-| clone |
`-------'
As the blobstore is preparing to be unloaded spdk_blob_unload(snap) is
called once for eclone, once for clone, and once for snap. The last of
these calls happens just before spdk_bs_unload() is called.
spdk_blob_unload() needs to destroy channels on each thread. During this
thread iteration, spdk_bs_unload() starts. The work performed in the
iteration maintains a reference to the blob, and as such it
spdk_bs_unload() cannot do its work until the iteration is complete.

This adds support for inflate and decouple for esnap clones. Since there
are no immediate consumers that will provide back_bs_dev->is_zeroes()
that can return true, a shortcut is taken in that inflate and decouple
of esnap clones are the same.
