A lot of the proofs in SysInit and DRefine previously had to unfold opt_object,
which was really just an alias for cdl_objects with the arguments in the
opposite order! This commit deletes opt_object in favour of using cdl_objects
directly, which should slightly reduce the burden of unfolding.
IRQ Nodes are now their own object type in capDL. This makes it much easier
to distinguish between "real" CNodes and IRQ Nodes.
Updated:
* the capDL refinement,
* the access proofs, and
* the system initialiser.
* The definitions of the separation "arrows" is slightly nicer and more consistent.
- We have a nicer correspondence between sep_map_c and sep_map_s.
- sep_map_irq now specifies exactly what the IRQ table contains
(that it *only* has one entry, not that it contains at least that entry).
- Nicer LaTeX output for the arrows.
* A number of minor renaming of constants and types.
- cdl_component => cdl_component_id
- sep_entity => cdl_component
- state_sep_projection => sep_state_projection
- obj_to_sep_state => object_to_sep_state
* Removed a few unused lemmas.
