AU: support for generating new style full updates.
New style full updates are full updates that use the delta upload file
format. A full update consists of sequential operations to write the
full kernel/rootfs in chunks (currently 128KiB).
Because these full updates use the new file format, they get benefits
over the old type of full update:
- support for embedded signatures
- (eventual) support for resuming installation across reboot
- help reduce code needed in the updater client software
