wp rules for most operators such as return, get, gets are named
return_wp, get_wp, etc. Then when, whenE, unless, unlessE operators had
an additional hoare_.. prefix that this commit removes for more
consistency.

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.
The things that usually go wrong:
- wp fall through: add +, e.g.
apply (wp select_wp) -> apply (wp select_wp)+
- precondition: you can remove most hoare_pre, but wpc still needs it, and
sometimes the wp instance relies on being able to fit a rule to the
current non-schematic precondition. In that case, use "including no_pre"
to switch off the automatic hoare_pre application.
- very rarely there is a schematic postcondition that interferes with the
new trivial cleanup rules, because the rest of the script assumes some
specific state afterwards (shouldn't happen in a reasonable proof, but
not all proofs are reasonable..). In that case, (wp_once ...)+ should
emulate the old behaviour precisely.
* 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.
