ps2: remove update_irq() function and update_arg parameter
Now that all the PS2 devices have been converted to use GPIOs the update_irq()
callback function and the update_arg parameter can be removed.
This allows these arguments to be completely removed from ps2_kbd_init() and
ps2_mouse_init(), along with the transitional logic that was added to
ps2_raise_irq() and ps2_lower_irq().

Currently we use 'id' option as the name of VDUSE device.
It's a bit confusing since we use one value for two different
purposes: the ID to identfy the export within QEMU (must be
distinct from any other exports in the same QEMU process, but
can overlap with names used by other processes), and the VDUSE
name to uniquely identify it on the host (must be distinct from

block/gluster: correctly set max_pdiscard
On 64-bit platforms, assigning SIZE_MAX to the int64_t max_pdiscard
results in a negative value, and the following assertion would trigger
down the line (it's not the same max_pdiscard, but computed from the
other one):
qemu-system-x86_64: ../block/io.c:3166: bdrv_co_pdiscard: Assertion
`max_pdiscard >= bs->bl.request_alignment' failed.
On 32-bit platforms, it's fine to keep using SIZE_MAX.
The assertion in qemu_gluster_co_pdiscard() is checking that the value
of 'bytes' can safely be passed to glfs_discard_async(), which takes a
size_t for the argument in question, so it is kept as is. And since
max_pdiscard is still <= SIZE_MAX, relying on max_pdiscard is still
fine.

qemu-img: rbd:rbd/namespace/image: error rbd create: No such file or directory
Unfortunately rados_ioctx_set_namespace() does not fail if the namespace
does not exist, so let's use rbd_namespace_exists() in qemu_rbd_connect()
to check if the namespace exists, reporting a more understandable error:
$ qemu-img create rbd:rbd/namespace/image 1M
Formatting 'rbd:rbd/namespace/image', fmt=raw size=

qemu-img: rbd:rbd/namespace/image: namespace 'namespace' does not exist

libvduse: Add support for reconnecting
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.

vduse-blk: Add vduse-blk resize support
To support block resize, this uses vduse_dev_update_config()

vduse-blk: Implement vduse-blk export
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 vduse-blk,node-name=drive0,id=vduse-export0,writable=on
After the qemu-storage-daemon started, we need to use
the "vdpa" command to attach the device to vDPA bus:
$ vdpa dev add name vduse-export0 mgmtdev vduse
Also the device must be removed via the "vdpa" command
before we stop the qemu-storage-daemon.

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