cb3d98d596 nvmf: fix nvmf_tgt_create_poll_group() cleanup
On failure, we weren't cleaning up the poll group data properly, and in
one place, we were trying to remove ourselves from the tgt-> list prior
to being on it.

79415753ea bdev: register bdev's UUID as its alias
In many cases, addressing bdevs by their UUIDs is often easier than
using their names, which can be somewhat arbitrary.  For instance, the
NVMe bdev builds a name by addng the n{NSID} suffix to the controller's
name, while the UUID is filled with NGUID (if available).

The UUID alias is stored in the form defined by RFC 4122, meaning five
groups of lower-case hexadecimal characters.  It's important to note
that bdev layer uses case-sensitive name comparison, so the user needs
to use the same textual UUID representation.

c5d80a8bc3 blob: avoid recursion when split IO immmediately complete
In some scenarios, a split IO can immediately complete.  For
example, a very large unmap operation to a newly thin-provisioned
blob has no operations to perform, so the batch for its operation
immediately completes.

But if it immediately completes, we can't recursively submit
the next split IO.  So use variables in the context structure
to detect when an operation immediately completes, to allow
it to unwind and submit the next operation without recursing.

Fixes issue #2347.

af1c4f7ffb lvol: finish initial iteration even if blob has no name
If we find a blob during the initial iteration during load
that doesn't have a name, we cannot just immediately
unload the blobstore, since the 'bad' blob is still
open.  Instead finish the iteration, and unload the
blobstore (with failure status) after the iteration
is complete.

This is somewhat related to issue #1831. By ensuring
we can unload the blobstore, it closes the open
descriptor on the underlying bdev, which allows
the bdev subsystem to exit on application shutdown.

047c067c05 so_ver: increase all major versions
To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.

Increasing major so version after LTS, allows the future releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.

Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 22.05
release.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

96212d45cc lvol: lvol_get_xattr_value failure undetectable
When an unexpected xattr name is passed to lvol_get_xattr_value(), no
error is returned to the caller. The one caller, blob_set_xattrs() via
the xattrs->get_value callback, makes the reasonable assumption that a
lookup that fails to find a value returns a NULL value.  This updates
lvol_get_xattr_value() to match that expectation.

d1c2027d01 nvmf/vfio-user: add NVMe live migration support finally
VFIO in QEMU uses region 9 as the PCI passthrough devices' migration channel.

The format of the region 9 migration region is as follows:
 ------------------------------------------------------------------
|vfio_device_migration_info|    data section                      |
 ------------------------------------------------------------------
QEMU will access vfio_device_migration_info to controll the migration
process.

For SPDK vfio-user target, we also implement the BAR9 via libvfio-user,
and we also define the NVMe device specific migration data stored in
data section of BAR9.  QEMU doesn't care about the format in data section,
it will help us to gather the NVMe specific migration data in source VM and
then restore the migration date to data section of BAR9 in destination VM.

The core idea to implement live migration will following the device state
change which is controlled by QEMU.  First QEMU will try to STOP the device
in the source VM, and set the destination VM to RESUME state, SPDK will save
NVMe devic state data structure to BAR9 in the source VM once the subsystem
is paused, then QEMU will read BAR9 in source VM and restore the content of
BAR9 in destination VM, finally in the destination VM, we will restore the
NVMe device state include BARs/PCI CFG/queue pairs in the destination VM.

So necessary delete operations are not done for adminq.

478f652436 nvmf: Update controller desctruction process
There is a race condition between controller destruction and
subsystem state change, e.g. admin qpair may already be freed
when a namespace is added or removed. As result in function
poll_group_update_subsystem we may get heap-use-after-free error

Another problem is that some qpair's live time may exceed controller's
life time. To avoid it, start controller destruction process when the last
qpair finished the disconnect process (previously controller started
the descruction process before the last qpair starts to disconnect
and it could lead to raise conditions)

Fixes #2055

Using contructor/destructor to handle g_dpdk_sem will
help later in the series when splitting vhost fini
between vhost.c and virtio abstraction.

Otherwise multiple callbacks would be needed during vhost fini.
Ex. spdk_vhost_fini -> vhost_user_fini to stop the sessions ->
-> back to spdk_vhost_fini to remove vhost devices ->
-> vhost_user_fini to destroy the g_dpdk_sem

g_dpdk_sem will only be used from rte_vhost_user.c.
Until all references are moved, it is placed in vhost_internal.
