Summary:
This diff adds a make target to generate interface files from
implementation files. These generated interface files can then be used
as a starting point for documenting and restricting the exposed module
interface. For example, to generate an interface for JavaTaintAnalysis.ml,
execute:
```
make -C infer/src M=quandary/JavaTaintAnalysis mli
```
Note that this relies on `ocamlc -i`, which for reason currently
produces syntactically ill-formed files.

Summary:
During the development/debugging of AST checks, it will be possible to emit dotty graphs with a representation of the evaluation of formulas.
The formulas, expressed using the notation of CTL (https://en.wikipedia.org/wiki/Computation_tree_logic) are represented in a graph alongside the current ast-node and their final evaluation result (green for true, red for false)
To get the dotty graph, run infer with the `--debug` flag

Summary:
This fixes a perf issue on large files, where a copy of the type environment and control flow graph were loaded for each procedure analyzed in the file.
If the type environment or the control flow graph are big, and the file contains many procedures, this can cause a big memory overhead.

Summary:
This changes executions of the former InferClang into a function call. In
particular, it can be called several times per execution.
The new InferClang must be called as if it was clang, and knows how to run
clang with our plugin to get the AST of the source file.

This diff removes the unused support for reporting props, which enables
refactoring so that the 'base' directory has no dependencies, and the
'IR' directory depends only on 'base'.

This changes the algorithm for pure join to keep the constraints that,
after normalization, occur in both arguments. Previously pure join
would normalize, filter, and then union the constraints of the
arguments.

Summary:
This is needed for later: InferClang will no longer be started once for each
source file to be analysed. Instead, it will be called to analyse several files
at once, and will analyse them one by one. Thus, `clang_lang` and `source_file`
are moved to `cFrontend_config` as references.
The biggest change this entailed was the new logging infrastructure, which was
depending on `Config.source_file`. This diff moves the logic entirely to
`Logging`, and changes the API so that executables wishing to log into files
have to set it up using `Logging.set_log_file_identifier`. This can be called
several times during the execution, allowing to dynamically change the log file
(eg, when analysing several source files one by one!).

Let's start migrating some of our bash script to OCaml to make them easier to

For now replace just one script and put it in lib/clang_wrappers/ at compile

later.

Summary:
We were previously leaking the passthroughs of the callee into the caller.
We definitely don't want to do this since it could make the summaries higher up in the call stack explode.
If we need to know the passthroughs of a callee, we can always read them from the callee's summary.
