treewide: rename Xen to Xen Project
Xen is a trademark of the Cloud Software Group; we're not packaging Xen(Server), we're packaging the Xen Project Hypervisor, which is open source and owned by the Linux Foundation. This is based on advice from Kelly Choi, the Xen Project Community Manager, who has assisted us in the branding aspects of pacakaging. Signed-off-by: Fernando Rodrigues <alpha@sigmasquadron.net>

- Support for mounting filesystems from block devices protected with [dm-verity](https://docs.kernel.org/admin-guide/device-mapper/verity.html)
|

was added through the `boot.initrd.systemd.dmVerity` option.

Booting into Xen through a legacy BIOS bootloader or with the legacy script-based Stage 1 initrd have been **deprecated**. Only EFI booting and the new systemd-based Stage 1 initrd are supported.

- There are two flavours of Xen available by default: `xen`, which includes all built-in components, and `xen-slim`, which replaces the built-in components with their Nixpkgs equivalents.
|
||||
- The `qemu-xen-traditional` component has been deprecated by upstream Xen, and is no longer available in any of the Xen packages.

- The `qemu-xen-traditional` component has been deprecated by the upstream Xen Project, and is no longer available in any of the Xen Project Hypervisor packages.
|

- The OCaml-based Xen Store can now be configured using [`virtualisation.xen.store.settings`](#opt-virtualisation.xen.store.settings).
|
||||
- The `virtualisation.xen.bridge` options have been deprecated in this release cycle. Users who need network bridges are encouraged to set up their own networking configurations.
