libblkio 1.5.0 release

This release updates cargo dependencies for building downstream Debian
and Fedora packages. It contains no API changes.

Cargo:
- rustix has been updated to 0.38 to enable building on current Linux
  distros.
- The minimum supported Rust version (MSRV) has increased from 1.56 to
  1.63 due to the rustix update. This is not a breaking change in
  semver, so bump the version minor number (rationale:
  https://github.com/rust-lang/api-guidelines/discussions/231).

virtio-driver 0.6.1 release

Cargo:
- rustix has been updated to 0.38 to enable building on current Linux
  distros.
- The minimum supported Rust version (MSRV) has increased from 1.56 to
  1.63 due to the rustix update. This is not a breaking change in
  semver, so bump the patch version number (i.e. pre-1.0 minor version
  number). Rationale:

blkio 0.5.0 release

New features:
- Zoned storage support (except zone append) is available in the
  nvme-io_uring driver.
- BLKIO_REQ_FUA is supported on "write zeroes" requests.

virtio-driver v0.6.0 release

Features:
- Packed virtqueue support has been added.

API changes:
- VirtqueueLayout::new() now takes a feature flags argument.
- Virtqueue::new() now takes a feature flags argument.
- VirtqueueCompletion::idx has been renamed to id.
- VirtqueueLayout::avail_offset has been renamed to driver_area_offset.
- VirtqueueLayout::used_offset has been renamed to device_area_offset.
- Virtqueue::avail_ring_ptr() has been renamed to driver_area_ptr().
- Virtqueue::used_ring_ptr() has been removed to device_area_ptr().

virtio-driver v0.5.0 release

API changes:
- VhostVdpa::new() has been replaced by ::with_path() and ::with_fd().

Dependencies:
- The nix crate dependency has been replaced with the rustix crate to simplify licensing.

Other:
- The minimum Rust version has increased to 1.56.

blkio 0.4.0 release

New properties:
- The "flush-needed" property was added to indicate whether a flush
  request must be sent after write request completion to ensure data
  persistence.
- The "fd" property was added to virtio-blk-vhost-vdpa to support file
  descriptor passing.
- The "can-grow" property was added to nvme_io_uring.

Dependencies:
- The paste crate has replaced the concat-idents crate to simplify
  licensing.
- The rustix crate has replaced the nix crate to simplify licensing.
- The const-cstr crate dependency has been dropped.

Other:
- The minimum Rust version has increased to 1.56.

While this release preserves source-level compatibility, I have chosen
to make this release an incompatible version change (0.3.2 -> 0.4.0)
because the Rust version, dependency, and overall license changes may
require manual action by users.

libblkio: bump version to 1.2.2

meson.build. Also update to the latest blkio release.

libblkio: bump version to 1.2.1

No API changes.

Use the fixed blkio 0.3.1 crate.

blkio 0.3.1 release

The blkio 0.3.0 release depended on virtio-driver "0.4" but actually
needs virtio-driver 0.4.1 or later for the new virtio_blk_max_queues()
API.

Fix the incorrect virtio-driver version constraint.

libblkio: bump version to 1.2.0

API changes:
- Add support for adding/removing queues to/from a started blkio via
  blkio_add_queue()/blkio_remove_queue() and
  blkio_add_poll_queue()/blkio_remove_poll_queue().

Crate dependency changes:
- io-uring 0.5.10 is now the minimum version.

Other changes:
- Enable virtio-blk-vhost-user and virtio-blk-vhost-vdpa test suites.
- Improve packaging friendliness for upcoming Fedora rpm.

blkio: bump version to 0.3.0

API changes:
- Add support for adding/removing queues to/from a started blkio via
  blkio_add_queue()/blkio_remove_queue() and
  blkio_add_poll_queue()/blkio_remove_poll_queue().

Crate dependency changes:
- io-uring 0.5.10 is now the minimum version. I treated this as a major
  change and therefore bumped blkio's version to 0.3.0.

virtio-driver v0.4.1 release

API changes:
- Add virtio_blk_max_queues() for querying the number of queues from the
  virtio-blk config space field
