Summary:
The disjunctive domain shouldn't really be a set in the first place as
comparing abstract states for equality is expensive to do naively
(walking the whole maps representing the abstract heap). Moreover in
practice these sets have a small max size (currently 50 for pulse, the
only client), so switching them to plain lists makes sense.

Summary:
It's useful to keep the size of states down, especially when humans are
trying to read it. It will also help keep the size of summaries down in
the inter-procedural pulse.

Summary:
You can only take the address of variables, field accesses, and array
accesses, the rest doesn't make sense.

It assigns symbolic values for global variables in the load commands. However, it does not instantiate the symbols for the global variables yet, which will be addressed in another diff.

- docstrings
- mli
- split `get_control_maps`: `get_loop_head_to_source_nodes` is used both by Cost and Hoisting. If using both analyzers, it is called twice whereas it could be shared (which is done later in the stack of diffs).

Summary:
:
Since traces are attached to symbols, currently it will make no difference.
Calling `subst` on `Top` or on constant is constant-time.
But I need this to record `Call` trace elements for `Top`.

Summary:
The Eradicate backend is reporting nullable type errors, that are not always necessarily leading to null pointer exceptions.
For example, the analysis is designed to be consistent with the Java type system and report on the following code:
String foo(boolean test) {
Object object = test ? new Object() : null;
if (test) {
return object.toString(); // the analysis reports here
}
}
even though the code will not crash.
In order to make this aspect clear, this diff renames the warnings `Null Method Call` and `Null Field Access` into `Nullable Dereference`

`Utils.with_intermediate_temp_file_out` is conceptually simpler. Plus,
this removes a dependency on Unix.flock, which is not portable under
Windows.
