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.

An esnap clone needs special handling as snapshots are created and
removed. In particular: the following must exist on the blob that
directly references the external snapshot and must be removed from
others:
- Ensure SPDK_BLOB_EXTERNAL_SNAPSHOT invalid flag exists only on the
esnap clone.
- Ensure BLOB_EXTERNAL_SNAPSHOT_ID internal xattr exists only on the
esnap clone.
- Clean up any esnap IO channels on a blob that is no longer an esnap
clone due to snapshot creation or removal.
See the diagrams and description in blob_esnap_clone_snapshot() in

The channel passed to blob IO operations is useful for tracking
operations within the blobstore and the bs_dev that the blobstore
resides on. Esnap clone blobs perform reads from other bs_devs and
require per-thread, per-bs_dev channels.
This commit augments struct spdk_bs_channel with a tree containing
channels for the external snapshot bs_devs. The tree is indexed by blob
ID. These "esnap channels" are lazily created on the first read from an
external snapshot via each bs_channel. They are removed as bs_channels
are destroyed and blobs are closed.

Let us consider the following process:
1. one fabric connect request A comes but the subsystem is paused
due to adding/removing ns or other operations, so this request A
will be put into sgroup->queued until the subsystem becomes active;
2. the subsystem is paused for a long time until the connect timeout,
related qpair is destroyed, the sgroup->queued will not be cleaned
because qpair's ctrlr is NULL;
3. if a new request B comes, it is more likely to be allocated to the
same memory as the previous fabric command request. And it will be
put into sgroup->queued again, where has already exists the exactly
same pointer with request B.
This leads to the pointer hanging problem and it will cause infinitely
loop when traversing sgroup->queued!
So this patch avoids the ptr-hanging problem by checking and cleaning
all sgroups queued req whose qpair is the being destroyed qpair in
_nvmf_qpair_destroy when ctrlr is NULL.
This problem is already described in issue #2133.

when one convert to seconds and then multiply

for example if one have 77ms, it will go to 0 when converted to seconds
and then multiply that 0 by 1000 will return 0 instead of 77ms.
- fix mismatch nsec/usec
nsec was multiplied by 1000*1000 while usec by 1000*1000*1000
it should be the opposite.
anyway the implementation had changed.
- implementation description
* env_ticks_to_msec: j / (tick_hz / 1000)
this is exactly the same as (j * 1000) / tick_hz (eq #2).
but this implementation (eq #2) can only handle 54b in j (before overflowing)
because of the multiplication by 1000 (10b).
with the correct implementation we use all 64b in j.
we assume that tick_hz will be prefectly divisible by 1000 so we are ok.
* env_ticks_to_usec: j / (tick_hz / (1000 * 1000))
same as in msec case, we use all 64b in j.
here we assume that tick_hz is perfectly divisible by (1000 * 1000)
i.e. we assume that CPU frequency is some multiple of 1MHz.
* env_ticks_to_nsec: (j * 1000) / (tick_hz / (1000 * 1000))
in this case we can't assume that tick_hz is divisible by 10^9
because there are many CPUs with 2.8GHz or 3.3GHz for example.
so we multiply j by 1000
this means that we can only handle correctly j up to 54b.

If we find that the discovery entry already exists, a
single break doesn't work - that just breaks out of
the TAILQ_FOREACH. So instead change it to free
the resolver object and return directly.
Fixes issue #2945.

During resize, we correctly determine if we have enough
md_pages for new extent pages, before proceeding with
actually allocating clusters and associated extent
pages.
But during actual allocation, we were incrementing
the lfmd output parameter, which was incorrect.
Technically we should increment it any time
bs_allocate_cluster() allocated an md_page. But
it's also fine to just not increment it at the
call site at all - worst case, we just check that
bit index again which isn't going to cause a
performance problem.
Also add a unit test that demonstrated the original
problem, and works fine with this patch.
Fixes issue #2932.

If blob_freeze_io() is called twice in a row,
and the second time occurs before the for_each_channel
for the first completes, the second caller will
receive its callback too soon.
Instead just simplify the whole process, always do
the for_each_channel and don't try to optimize it
at all. These are infrequent operations - correctness
and simplicity are in order.
A few additional changes:
1) Make same changes for unfreeze path.
2) Add blob_verify_md_op() calls, just to be sure
these are only called from md_thread. This was
already checked in calling functions, but as these
functions get called from new code paths (i.e.
esnap clones) it can't hurt to add additional
checks.
3) Add unit test that failed with original code, but
passes with this patch.
Fixes issue #2935.

It is quite common for a user to use the exact same iovec (in memory) to
describe buffers for two different operations. If that iovec was
describing accel buffer, accel would modify it replacing it with an
actual buffer. This is broken if that iovec was used by some other task
in a sequence, as accel wouldn't be aware that it has been changed too.
To address this, accel will use a new iovec from the aux_iovs array. It
means that accel buffers always *must* be passed using a single iovec.
Theoretically, users could chunk that buffer into several iovecs, but
spdk_accel_get_buf() always returns a single buffer, so, in practice,
this should never happen, and therefore is unsupported.
