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)

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.

Summary:
Remove the remaining uses of polymorphic equality `=`.
In case of basic types, this is replaced by String.equal or Int.equal.
In case of `= []`, this is replaced by `List.is_empty`.
In case of `= None`, this is replaced by `is_none`.
In case of a datatype definition such as `type a = A | B`,
a `compare_a` function is defined by adding `type a = A | B [@deriving compare]`
and a `equal_a` function is defined as `let equal_a = [%compare.equal : a]`.
In case of comparison with a polymorphic variant `= `Yes`, the equality
defined in `PVariant.(=)` is used. Typically, `open! Pvariant` is added
at the beginning of the file to cover all the uses.

Summary:
Implement heuristic to capture more of the user code:
In C++ there is a lot of interesting code in header files. On the other hand,
that code gets included in multiple places and we don't want to capture it by default (for performance reasons).
Right now we capture everything from source file + all symbols from headers that source file needs.
New heuristic will extend "capturing everything" to matching header files (ie. capture everything in X.h if source file is X.cpp)

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.

fbshipit-source-id: 7af6490
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!).

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:
Reimplement command line options in preparation for uniformly passing
options from the top-level infer driver that invokes a build command
through the build system to the descendant infer processes.
All command line options of all executables are collected into Config,
and declared using a new CommandLineOption module that supports
maintining backward compatibility with the current command line
interface. Very few values representing command line options are
mutable now, as they are set once during parsing but are constant
thereafter. All ordering dependencies are contained within the
implementation of Config, and the implementation of Config is careful to
avoid unintended interactions and ordering dependencies between options.
