module/vfu_device: vfu_virtio_fs introduced

This patch set implements the virtiofs vfio-user device based on SPDK fsdev +
FUSE dispatcher.

Steps to run w/QEMU:

1. Run target:

build/bin/spdk_tgt -S /tmp/vfio-sockets

2. Create an fsdev and a corresponding vfu endpoint:

spdk_rpc.py fsdev_aio_create aio0 /tmp/vfio-test
spdk_rpc.py vfu_virtio_create_fs_endpoint vfufs.0 --fsdev-name aio0 \
--tag vfu_test --cpumask=0x1 --num-queues=8 --qsize=256 --packed-ring

3. Run the QEMU with:

-device vfio-user-pci,socket=/tmp/vfio-sockets/vfufs.0

Then inside the VM:

$ mkdir /tmp/zzz
$ modprobe -v virtiofs
$ mount -t virtiofs vfu_test /tmp/zzz

NOTE: as the implementation is based upon the nutanix/libvfio-user library
([1]) similar to vfu_virtio_blk and vfu_virtio_scsi. It requires an QEMU
version that supports the vfio-virtio-pci devices. More information can be
found in the libvfio-user README ([2]).

so_ver: increase all major versions after SPDK 24.01

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.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components

Due to patch below being introduced after v24.01 code freeze,
bdev lib version should not be increased:
61623c5ca9 bdev: add spdk_bdev_io padding in place of io_submit_ch

Short reference to how the versions were changed:
MAX=$(git grep "SO_VER := " | cut -d" " -f 3 | sort -ubnr | head -1)
for((i=$MAX;i>0;i-=1)); do find . -name "Makefile" -exec \
sed -i -e "s/SO_VER := $i\$/SO_VER := $(($i+1))/g" {} +; done
find . -name "Makefile" -exec \
sed -i -e "s/SO_MINOR := .*/SO_MINOR := 0/g" {} +

Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 23.05
release.
Looks like this was left over from prior LTS, to avoid that
make sure it is only skipped when running against v23.01.x as latest
release.

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

below. The policy does not apply to non-Intel (C) notices.

git log --follow -C90% --format=%ad --date default <file> | tail -1

and then pull just the 4 digit year from the result.

Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc). Contribution date used
"--follow -C95%" to get the most accurate date.

Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line. Simply there for
consistency.
