First step to be able to enable and disable the checkers to run in the following form:

and have a predefined list of checkers that are run by default with:

Summary:
While working on making the AI framework simpler to use, it become hard to change the shared API while keeping these unused checkers compiling, and even harder to keep their functionality since there is no tests for them.
Also, these checkers are not useful as proof of concept since using the AI framework is the preferred way to write new kinds of analysis now.

Summary:
This gives the option to run the biabduction analysis together with the other Clang-based checkers with the command:
infer -a checkers --biabduction -- ...
The filtering does not work yet because the filtering for the biabduction analysis matches the analyzer `Infer`, and does not filter much when the analyzer is `Checkers`, which is the case here.

Last step for converting thread-safety and quandary to HIL.
Push the logic for managing the id map and converting the instructions into a functor.
This way, client analyses can simply write HIL transfer functions and call the functor.

Don't store redundant information in C++ template Type.Name.t.
New signature:
```

For example, for `std::shared_ptr<int>`, will look like this:
```
| CppClass (["std", "shared_ptr"], Template [int])
```
While it used to be:
```
| CppClass (["std", "shared_ptr<int>"], Template (["std", "shared_ptr"], [int]))

Summary: The Java frontend creates a single `tenv` file per `javac` invocation, but the code loading the `tenv` for a given Java procedure in the backend was not taking advantage of it. Also, with the lazy dynamic dispatch algorithm, the procedure name can be created on-demand and therefore defeat the approach to load the tenv by looking at the call graph to associate existing procedure names to the corresponding serialized tenv file. This diff should also fix this last point.

Title.
The way types are printed is completely valid, but little weird for some C++ programmers:
`int const` - same as `const int`
`int * const` - pointer is `const`, value under it is not
`int const *` - pointer is not `const`, but the value is
`int const * const` - both pointer and value are const

`libstdc++` includes `bits/unique_ptr.h` via `include "unique_ptr.h"` in `bits/locale_conv.h` which infer can't redirect to model headers. This leads to compilation issues.

This diff changes bunch of things:
- update clang plugin to have AST exporter actually export that info most of the time
- change types of functions in clang frontend until it compiles
- replace `type_ptr` with `qual_type` and `tp` with `qt` in names where applicable
- cleanup some things in the process
