This is vmspawn's per-backend code for the StorageProvider integration.
Other backends (future systemd-nspawn, future service-manager
BindVolume=) consume the same shared parser and Acquire helper but
each provides its own attach/detach glue; this is vmspawn's.
- disk_type_from_bind_volume_config() turns the opaque BindVolume
'config' field (e.g. "scsi-cd") into a DiskType. Empty defaults to
virtio-blk to match the --bind-volume CLI grammar.
- vmspawn_bind_volume_acquire() takes a parsed BindVolume, calls
storage_acquire_volume() for the fd, and builds a DriveInfo ready
for vmspawn_qmp_setup_drives() (boot) or vmspawn_qmp_add_block_device()
(hotplug). Rejects directory-typed volumes (vmspawn block devices
need a regular file or a host block device).
- vmspawn_bind_volume_attach_fd() is the runtime path: takes a fd
that was already pushed across by an AddStorage caller plus the
name+config it specified, builds the DriveInfo with
QMP_DRIVE_REMOVABLE set and a varlink link, and dispatches to
vmspawn_qmp_add_block_device(). Reply is delivered asynchronously
by the existing on_add_device_add_complete() callback.
- vmspawn_bind_volume_prepare_boot() is a thin loop the boot-time
path uses to populate DriveInfos.
