Summary:
- delete getter for `CContext.context.procdesc`
- change API of `CLocation`, in particular to take just a source file instead of a `CContext` since that's all they need (but maybe we'd rather type less?)
- thread `source_range` of source statement to where useful for logging (could do more in the future)

Summary:
- failwith police: no more `failwith`. Instead, use `Logging.die`.
- Introduce the `SimpleLogging` module for dying from modules where `Logging`
cannot be used (usually because that would create a cyclic dependency).
- always log backtraces, and show backtraces on the console except for usage errors
- Also point out in the log file where the toplevel executions of infer happen

Summary:
Conversion and reformat of infer source using ocamlformat
auto-formatting tool.
Current status:
- Because Reason does not handle docstrings, the output of the
conversion is not 'Warning 50'-clean, meaning that there are
docstrings with ambiguous placement. I'll need to manually fix
them just before landing.

Module CFrontend_utils is a container for two modules: Ast_utils and General_utils.
Instead of opening CFrontend_utils in several places, it is now split into two separate modules CAst_utils and CGeneral_utils, which are now accessed directly.

Summary:
This diff allows to use the linters written in DSL to check for bugs.
Now new checkers can be written directly in the DSL.
The diff also remove some weirdness and simplify the CTL semantics.
For example no need to unwrap a node when evaluating the IN operator.
Also no need to distinguish anymore between stmt and decl in the
semantics of EX and EF.
Moreover, the diff de-couple hard-coded checkers (eg checks on component kit)
from those checkers parsed in the .al files.

Summary:
This diff introduces place-holders strings in error messages and evaluates them
when an error needs to be reported.
Place-holders strings are of the form %name_of_helper_function%. They will be evaluated
using and helper function that gives a value.
For example if we need to display the name of a variable in the error message we will have:
".... %var_name%...."
then %var_name% will be evaluated in the ast node calling the appropriate
helper function and the results will replace %var_name% in the message.

Summary:
Utils contains definitions intended to be in the global namespace for
all of the infer code-base, as well as pretty-printing functions, and
assorted utility functions mostly for dealing with files and processes.
This diff changes the module opened into the global namespace to
IStd (Std conflict with extlib), and moves the pretty-printing
definitions from Utils to Pp.

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.

There were overly complex and different ways of identifying C++/objC languages. Simplify and unify them.
How I came up with naming - there are two languages C and C++. You can apply "Objective-" extention to both of them.
We usually need to differentiate C and C++ (different AST) and whether it's extended (checks specific to ObjC)
