The vhost-user-blk export runs requests asynchronously in their own
coroutine. When the vhost connection goes away and we want to stop the
vhost-user server, we need to wait for these coroutines to stop before
we can unmap the shared memory. Otherwise, they would still access the
unmapped memory
To support block resize, this uses vduse_dev_update_config()
to update the capacity field in configuration space and inject
config interrupt on the block resize callback.

VDUSE [1] is a linux framework that makes it possible to implement
software-emulated vDPA devices in userspace. This adds a library
as a subproject to help implementing VDUSE backends in QEMU.

This adds vduse header to standard headers so that the
relevant VDUSE API can be used in subsequent patches.

This implements a VDUSE block backends based on
the libvduse library. We can use it to export the BDSs
for both VM and container (host) usage.
The new command-line syntax is:
$ qemu-storage-daemon \
--blockdev file,node-name=drive0,filename=test.img \
--export
To support reconnecting after restart or crash, VDUSE backend
might need to resubmit inflight I/Os. This stores the metadata
such as the index of inflight I/O's descriptors to a shm file so
that VDUSE backend can restore them during reconnecting.

Hi all,
Last few months ago, VDUSE (vDPA Device in Userspace) [1] has
been merged into Linux kernel as a framework that make it
possible to emulate a vDPA device in userspace. This series
aimed at implementing a VDUSE block backend based on the
qemu-storage-daemon infrastructure.

The previous commit removed all uses of libxml2.
Refresh lcitool submodule, update qemu.yml and refresh the generated
files by running:
