Add extensible import system to convert fetched source formats
(tarballs, qcow2, etc.) into Xen-ready disk images at build time.
Built-in import types:
- rootfs_dir: extracted directory → ext4 via mkfs.ext4 -d
- qcow2: QCOW2 → raw via qemu-img convert
- ext4/raw: copy passthrough
Per-guest varflags control the import:
XEN_GUEST_SOURCE_TYPE[guest] = "rootfs_dir"
XEN_GUEST_SOURCE_FILE[guest] = "alpine-rootfs"
XEN_GUEST_IMAGE_SIZE[guest] = "128"
Also adds three kernel modes for resolve_bundle_kernel():
- (not set): shared host kernel from DEPLOY_DIR_IMAGE
- "path": custom kernel, checks UNPACKDIR then DEPLOY_DIR_IMAGE
- "none": HVM guest, omits kernel= from config
Native tool dependencies and fakeroot are resolved automatically
at parse time. External guests emit a single license warning at
do_compile time (prefunc, not parse-time).

New bbclass that creates installable packages bundling Xen guest
images (rootfs + kernel + config). When installed via IMAGE_INSTALL
into a Dom0 image that inherits xen-guest-cross-install, guests are
automatically deployed by merge_installed_xen_bundles().
Features:
- Parse-time dependency generation from XEN_GUEST_BUNDLES
- Per-guest varflags for memory, vcpus, vif, extra, disk, name
- Custom config file support via XEN_GUEST_CONFIG_FILE varflag
- Explicit rootfs/kernel path overrides for external guests
- Manifest-based packaging for cross-install integration
