Summary:
Functions related to source files were already namespaced by `source_file_` prefix. Make separate module for them.
In high level it replaces all `source_file_` with `SourceFile.` and then fixes all remaining compilation errors

Summary:
`DB.source_file_to_string` is very easy to misuse and it shouldn't even exist.
In preparation for that day, replace most of `source_file_to_string` with `source_file_pp`

Summary:
This will help during the creation of new checkers, and will prevent errors like misspelling of AST node names.
It will also make it possible to fail immediately during the parsing of CTL inputs.

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 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!).

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.
