Currently this just modifies the rule but not any of the proofs that use
it. The old version is kept for now but should be removed once all of
the proofs are updated.

Abbreviate Hoare triples that do not care about the return value and
whose pre and post conditions are the same.

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.
in addition to the a_type ATCB simplification, the following two are now in the simpset:
"a_type (Endpoint x) = AEndpoint"
"a_type (Notification v) = ANTFN"
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.
* tcb_context rephrasing to (tcb_context o tcb_arch) and respectively
for set operations
* unfolding of reserved_irq for trivially solving most lemmas
* Changes to the inductive definition of integrity_obj to account for
tcb_arch and tcb_context new location
* Changes to the tcb examples in ExampleSystem to include tcb_arch
* Rephrasing of domain_sep_inv to accommodate the ReservedIRQ case
* Mostly rephrasing of tcb_context to (some form of) (tcb_context o tcb_arch)
* Trivial unfolding of handle_reserved_irq for hoare rules
* Examples in Example_Valid_State.thy were updated
* Nothing remarkable, mostly rephrasing of tcb_context and ReservedIRQ
handling
* Fun fact, some proofs are now shorter

This commit should at least remove merge conflict markers, and the idea
is that at least refine, crefine, drefine, and infoflow (with sorrys)
build. Subsequent commits may be required to fix build issues that I
have not picked up.
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.
