build. Subsequent commits may be required to fix build issues that I

Try to avoid emitting const-globals via memory.
...
Sometimes it's simpler to access an unknown field of a const
global by just computing the offset from its symbol in memory
and assuming the relevant words are in the .rodata section. But
for known fields, it's easier to just figure out what the
constant value is. This complicates the proof slightly, since
it has to guess which case it is in.

retire old obsolete ADT refinement phrasing
...
The observable state has been strengthened significantly years ago and
this theory has fallen into disrepair. The toplevel refinement statement
here was nicely concise for a paper, but the practical value is in the
much stronger corres statement, so instead of attempting proof
acrobatics with a new observable state, I'm retiring this theory.

infoflow: Change definition of "the_nat_to_bl" to avoid undefined outputs.

...and clean up some fallout.
In particular, we now say that the output of "nat_to_bl sz n" is taken
to be the bitlist of "n mod 2^sz", so the output is always defined.
The idea is to remove the undefinedness of "the_nat_to_bl" so that it is
easier to generate simp rules for it; some of these are developed in the
theory below, and simplify some of the more concrete infoflow proofs.

sys-init: Show the separation algebra for capDL is a cancellative separation algebra.
...
* The separation algebra for capDL is also a cancellative separation algebra.
* The arrows are strictly_exact, meaning they describe only a single heap.
* Since we have a cancellative separation algebra, this means the arrows are also precise.

Cleanup of a number of definitions of the separation algebra for capDL.
...
* 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.
