a4b975244d bdev/raid: Simplify variable name in struct raid_bdev
struct raid_bdev has a pointer raid_bdev_config to its configuration,
but raid_bdev is duplicated between raid_bdev and raid_bdev_config
and just config may be enough as a name.

a74212733b bdev/raid: Use raid_cfg as a pointer to raid_bdev_config throughout
In bdev_raid.c and bdev_raid_rpc.c, to hold a pointer to
raid_bdev_config, some have used raid_cfg and other have used
raid_bdev_config.

raid_bdev_config is the name of the struct and using the name of
the struct as a pointer to it may cause any confusion.

4bd9762165 bdev: add split_on_optimal_io_boundary
A number of modules (RAID, logical volumes) have logical
"stripes" that require splitting an I/O into several
child I/O.  For example, on a RAID-0 with 128KB strip size,
an I/O that spans a 128KB boundary will require sending
one I/O for the portion that comes before the boundary to
one member disk, and another I/O for the portion that comes
after the boundary to another member disk.  Logical volumes
are similar - data is allocated in clusters, so an I/O that
spans a cluster boundary may need to be split since the
clusters may not be contiguous on disk.

Putting the splitting logic in the common bdev layer ensures
bdev module authors don't have to always do this themselves.
This is especially helpful for cases like splitting an I/O
described by many iovs - we can simplify this a lot by
handling it in the common bdev layer.

Note that currently we will only submit one child I/O
at a time.  This could be improved later to submit multiple
child I/O in parallel, but the complexity in the iov splitting
code also increases a lot.

Note: Some Intel NVMe SSDs have a similar characteristic.
We will not use this bdev stripe feature for NVMe though -
we want to primarily use the splitting functionality inside
of the NVMe driver itself to ensure it remains fully
functional.  Many SPDK users use the NVMe driver without
the bdev layer.

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.

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).
