Summary: This cleans up the domain/transfer functions, and it also means that we can now track reads that occur under synchronization.

Summary:
Eradicate detects circular field initializations (e.g. a field initialized with itself)
by checking in the typestate at the end of the constructor whether the origin
of the field is a field name in the current class.
This has the problem that the following initialization pattern is not recognized as correct:
C(C x) { this.field = x.field }
To fix the issue, the origin information for field accesses x.f is extended
with the origin information of the inner object x.
Circularities are detected if the origin of x is "this".

Summary:
Given two analysis results, it's now possible to compare them with the following command:
infer --diff --report-current reportA.json --report-previous reportB.json --file-renamings file_renamings.json
this command will then generate 3 files in `infer-out/differential/{introduced, fixed, preexisting}.json`, whose meaning is the following:
- `introduced.json` has all issues in `current` that are not in `previous`
- `fixed.json` has all issues in `previous` that are not in `current`
- `preexisting.json` has all issues that are in both `current` and `previous`
The json files generated can then be used to categorise results coming from incremental analyses of a codebase.

Summary:
In order to be able to report races like
```
synchronized write() {
this.f = ...
}
read() {
return this.f;
}
```
, we need to track writes that happen inside of synchronization as well as writes that happen outside of synchronization.
This diff takes a step toward making that possible by defining an "AccessDomain" mapping a precondition for the safety of a write ( {Safe, SafeIf i, Unsafe} =~ {true, owned(i), false} ) to a set of writes that are safe if the precondition will hold.
We're not actually tracking safe writes yet, but this domain will make it easy to do so.
This also lets us kill the conditional writes/unconditional writes combo, which was a bit clumsy

This is helpful to make sure tests are up to date wrt the models.
Also made the Java deps depend on the models.jar instead of the model sources
as that's what the tests will be using. In particular, updating the sources of
the models will not update the results of a test unless someone rebuilds
models.jar, so rerunning the tests when the models haven't been rebuilt is
useless.
