In order to have only InferJava depend on JBasics, do not use
JBasics.java_lang_object in the IR or backend. Note that this implies
that the Java frontend should ideally translate JBasics.java_lang_object
to Typename.Java.java_lang_Object.

Summary:
This diff introduces a first version of a front-end checkers specification
language. The language is based on the CTL temporal logic that is interpreted
on trees. In this case the model for a formula is the AST of the program produced
by clang.
This diff introduce the language and translate most of the existing checks on
this new language. In other diff I will translate all the other checks.
Then I will generalize the framework to allow the developer to specify only
the CTL formula.

Summary:
The global reference `DB.current_source` is used internally in the module DB, by all the front-ends, and directly and indirectly by the back-end, including saving and restoring the state in case of on-demand procedure calls. In particular, it is heavily used in printing functions.
This diff cleans up the flow of information about what the current file is, making it explicit, and removes the reference.

Summary:
When a project defines the same symbol in different files,
the results of the capture will be different depending on
the order in which files are captured.
In particular, if a procedure with the same name is defined in different files,
it will be associated with the last file being captured.
So the results can be different if the files are processed in different order.
In case of parallel capture, this has in effect a non-deterministic behaviour.
This diff defines a canonical file (alphabetically) when a procedure is multiply
defined, so that the procedure is associated to the same file whatever the order.

Summary:
This diff fixes two issues in the backend that were causing Bad_footprint
errors when abducing pointsto facts for expressions that start in an array
access and follow up with another structured access, eg `x[0].some_field`:
1. array accesses were assumed to come last in these expressions
2. the type of the root exp passed to the function that walks down the list of
offsets to apply to it was wrong in the case of arrays: it was always the
type of the whole expression instead of the root expr (eg the type of
`x[0].some_field` instead of the type of `x`).

So far infer had very fragile mechanism to detect smart pointers. It was looking for "std" and "(shared|unique)_ptr" inside name string.
This is easy to trick (like mystd::shared_ptr) and not something we want.

via `using shared_ptr = infer_std_model<T>;`
