ea952fcaf2 bdev/split: remove resubmit logic
Issue each I/O to the base bdev as a new discrete I/O rather
than resubmitting the original I/O.  This enables some
upcoming changes to better handle queueing and reset-related
work at the generic bdev layer, which will also deprecate
the resubmit I/O logic.

900aef2c99 bdev/split: simplify structures and naming
1) Change each split_disk to just point to a
   split_base structure and drop the extra base_bdev
   member.  We can get the bdev from the split_base.
2) Simplify the names a bit for some of the members:
   split_base::base_bdev to split_base::bdev and
   split_disk::split_base to split_disk::base.

f054577df1 bdev: remove gencnt
gencnt is no longer really used since there is no more
differentiation between "soft" and "hard" reset.  The
original idea was that a hard reset would complete I/O
known to the bdev layer even if the underlying bdev
module had not actually completed it yet.  We do not
actually support that concept, and it was a bit flawed
anyways.

c2175d2c51 virtio: add initial rev of virtio-scsi initiator bdev module
Supports both PCI mode (for usage in guest VMs) and
vhost-user mode (for usage in host processes).  The rte_virtio
subdirectory contains a lot of code lifted from the DPDK
virtio-net driver.  Most of the PCI and vhost-user code is
reused almost exactly as-is, but the virtio code is drastically
rewritten as the DPDK code was very network specific.

Has been lightly tested with both the bdevio and bdevperf
applications in both PCI and vhost-user modes.

Still quite a bit of work needed - a list of todo
items is included in a README in the module's directory.

12b53038f6 bdev/aio: Poller handles inline channel deletion
Change the poller to tolerate channel deletion within
an I/O completion callback. This won't happen today
because channel deletion is always deferred, but
prepare for that case.

It turns out this is simpler anyway.

  * bdev->status = REMOVING
  * A->remove_cb is called
    * some poller is started
  * B->remove_cb is called
    * another poller started

* poller from A->remove_cb finishes it's work and closes the desc:
  * bdev_close(A)
    * A is removed from bdev->open_descs list
    * bdev->status is REMOVING, so bdev_unregister(X) is called again!

7fefd60fab bdev: make module init synchronous again
Module initializaiton was made asynchronous recently
to support bdev modules like gpt which need to do
asynchronous I/O.  But all modules now do any
asynchronous I/O in their examine() routines, and
init functions only do very basic operations to be
ready to handle examine() callbacks.

So simplify the bdev code and modules to go back to
a synchronous init procedure.

4fc7e66614 bdev: add vbdev claim/release semantics
vbdev modules still open/close bdevs as normal, but
should open bdevs read only when tasting (i.e. reading
the GPT to see if there are SPDK partitions).  When
a vbdev module is ready to claim the bdev for purposes
of creating virtual bdevs on top of it, it calls
spdk_vbdev_module_claim_bdev().  It can pass its
open descriptor as well to have it promoted to
write access (required for future vbdev modules like
logical volumes).

Note: error vbdev was changed to copy the base bdev
parameters one-by-one instead of a blind memcpy - we
do not want to copy the base bdev's vbdev_claim_module
into the new bdev!

8bf4c089f6 bdev: initialize vbdev modules first
This allows vbdev modules to be ready for examine
calls for (physical) bdev modules when the latter
initialize.

This requires the following modifications to existing
bdev modules:
1) error and split now search their config sections
   at examine time (instead of init) to see if the
   bdev should be consumed by the vbdev module
2) gpt is simplified considerably - it no longer
   needs to save bdevs to examine when
   gpt initializes later
3) nvme must register its io device before registering
   the bdev, since vbdevs may immediately start trying
   to send I/O to the new nvme bdev

This allows multiple clients to open a bdev,
although only one may open a bdev with write

Usually we can retry an I/O when a previous I/O completes,

things like counting the number of outstanding IOs for

account specially for resets).

Reset semantics are still that they affect the entire bdev
