5abf2ecfcd Do not recreate passthru vbdev unnecessarily.
The passthru module associates a vbdev and the underlying bdev.
This association lives throughout the lifetime of the module and because
of this, passthru vbdevs are recreated when they shouldn't be.

This patch ensures that the association between a vbdev and a bdev is
broken when the vbdev is removed, so that if the underlying bdev is ever
recreated (after being deleted), the vbdev does not reappear.

Note that this change does not affect hot-remove operations.

26628773d3 bdev/lvol: point directly to lvol->unique_id for bdev name
The lvol->unique_id will never change - so just point the
bdev->name directly to it.  That eliminates the need to
free bdev->name when cleaning up the bdev, and removes
an extra strdup.

1be2a279c3 bdev/lvol: have the RPC methods use lvol->unique_id
Ideally lvols would not point to bdevs (bdev/lvol
should be layered on top of lvol).  This is a small
step towards making that happen.

671b77e5cd bdev: remove vbdevs and base_bdevs arrays
The intents of these arrays was to keep track in the
bdev layer of all base<->virtual bdev relationships -
i.e. which member disk bdevs make up a RAID bdev,
which logical volume bdevs are associated with a
bdev that contains an lvolstore, etc.

Currently none of this is used however.  And trying
to keep track in the bdev layer instead of asking
the bdev modules for the relationships has a number
of complications.  Early one, we tried to do this
with TAILQs - but that doesn't work since this can't
be done with a single TAILQ_ENTRY in the bdev
structures.  So we moved to arrays - that works a bit
better, but then the pointer arrays have to be
realloc'd which isn't ideal.

The biggest problem though with these arrays is that
they held bdev pointers - not bdev descriptor pointers.
It's not really valid to access bdevs without a
descriptor - the descriptors are what make sure active
references are accounted for when a bdev is hotplugged.
Of course the bdev layer knows when a bdev is getting
removed and could go and do the updates to these
arrays separately - but that just seems very convoluted.

So for now just remove these arrays completely.  If
there is a future need for the bdev layer to
understand relationships between bdevs, we can add
module APIs so that the generic layer can ask
the modules about the relationships.

43c8d0eb1e bdev/split: use bdev_part interface to get split names
The base_bdev and vbdevs arrays are going away in the
common bdev layer in a future patch, so prepare for that
in the split RPCs to use the bdev_part interface instead
to get the names of the split bdevs created from the
base_bdev.

No change in observed functionality.

9ee4942130 bdev/gpt: fail more gracefully on extended block size bdevs
The GPT module isn't designed currently to support extended
block sizes like 520 or 4104, and we don't really have a good
way to put GPT down on one of these devices anyways.

So just check the block size when examining a new bdev, and
fail immediately if it's not an even multiple of 512.

Long-term, this should probably be a DEBUG print and not an
ERRLOG, but while we work through the bdev implications
of extended block sizes, keep it as an ERRLOG to facilitate
debugging.

c899854d03 bdev: add new fini_start notification callback for modules
When an SPDK application shuts down, the bdev layer will
automatically unregister all of the bdevs to ensure they
are properly quiesced and cleaned up.

Some modules may want to perform different operations when
a bdev is destructed during normal runtime vs. shutdown.
For example, for lvol, when the last lvol is cleaned up,
it should unload the lvolstore, release and close the bdev
that contains the lvolstore.  You never want to do this
during normal runtime though - it is perfectly valid to
have an lvolstore that contains no lvols.  RAID and future
bdev modules such as multipath have similar use cases.

So add a new bdev module callback named "fini_start".
If a module specifies a function pointer for this callback,
the bdev layer will call it before it starts the bdev
unregistrations.

This enables some future patches to the bdev layer such
that it will always unregister block devices that are not
claimed (i.e. logical volumes) before block devices that
are claimed (i.e. the bdev containing an lvolstore).

27635c770f bdev: track io_stats from deleted channels
Currently, the bdev layer iterates over all of the
existing channels of a bdev to collect I/O
statistics.  But this ignores statistics for
channels that are deleted.

Fix that by keeping an io_stat structure in the
bdev which accumulates statistics for deleted
channels.  Use the bdev mutex to protect these
accumulations.

b326e51219 bdev/virtio_blk: defer bdev destruct completion
Even after the bdev is removed, the underlying virtio
device may be still alive for some time. The user may
then try to recreate the virtio bdev and could technically
initialize a second simultaneous connection to a vhost
target. It does not cause any technical problems, but the
target may reject such connection if it reached a connection
cap or doesn't support more than one connection per target
(like SPDK vhost does as of today).

Since the fix is straightforward, here it is.

Note:
Virtio SCSI is already safe, because it uses a separate
completion callback to indicate virtio device destruction.

a1ec258ac7 Clean up some incorrect Copyright statements
Daisuke Aoyama originally contributed to istgt, the
iSCSI target in FreeBSD. The SPDK iSCSI code is
originally derived from that. Due to copy and paste,
some incorrect copyright attributions have been added
to other files that do  not derive from istgt, so
this patch removes those.

It is doubtful, at this point, that there is any code
whatsoever that remains from the original istgt, but
we can revisit that at a later time.

c60ae3c356 raid: get buffer on reads before sending child ios
For front-ends like iSCSI (and NVMe-oF in the future)
which want the backend to specify the data buffer, the
RAID module doesn't copy the pointer to the allocated
buffer from the child IO back to the parent IO.  It
really can't copy the pointer - the child IO owns it
and will free it.

So the RAID module needs to allocate the buffer first
and then pass it down.
