If accel sequence is supported, append a copy

fsdev/aio: add support for null IOs

This patch adds support for null IOs in the AIO fsdev by introducing
a new RPC flag (--enable-skip-rw) during fsdev creation.

When enabled, the AIO fsdev will skip read/write operations, similar
to how the null bdev operates in the bdev module.

This feature facilitates performance testing across the entire stack
without actual data read/write operations. Implementing this within
the fsdev/aio module, rather than creating a separate fsdev/null module,
avoids unnecessary code duplication and keeps the AIO fsdev focused as a
comprehensive example demonstrating various features, including null IO
capability.

lib/event: Add support for core isolation in scheduling

Added new 'scheduler_set_options' RPC.
1. isolated_core_mask: Users are allowed to select cores to isolate during scheduling
2. scheduling_core: Users are allowed to select main core of scheduling
This RPC can only be called before SPDK subsystems have been initialized.
These parameters can only be set once.

The following options are for general mechanisms.
For example, dynamic scheduler now allows specific cores to be isolated from scheduling
through the newly added isolated_core_mask. This means that no threads can enter
or leave the cores designated as isolated cores.

Core isolation can be useful in the following situation:
The user may want the main core to be dedicated to orchestration tasks(such as RPCs, etc.)
and does not want any IO work to be assigned to it while running dynamic scheduler.
These changes allow user to dedicate main thread for RPC, assign nvmf poll groups to
non-main thread cores, and then ensure that dynamic(or any other) scheduler will
not place any other spdk_threads on the main core.

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

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]).
