Summary:
Parse the inferconfig_home and project_root options in a separate phase
before other options. This enables using their values to e.g. find the
inferconfig file and process it prior to full option parsing.

Summary:
Create model of C++ std::vector to find occurrences when vector which might be empty is accessed. Do it by triggering null dereference every time empty vector access is performed.
Note: model will be used only when c++11 (or c++14) are used.

Summary:
The checkers check was causing perf issues because it kept loading the json of
inferconfig. To prevent this from happening again, load json files inside
config.ml, and only export `Yojson.Basic.json Lazy.t` values to other modules.
Also move the list of checks disabled by default into config.ml for better
discoverability.

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.

Summary:
Infer prepends the directory containing the ananotation processor and
the current working directory to the classpath javac option. This diff
enables prepending these to the classpath when it is passing in an args
file (as the classpath can get too long to pass on the command line).

Summary:
Add a module target to the src Makefile that builds a single module and
its dependencies, perhaps with extra flags. Useful for generating
assembly or interfaces, as well as directing the typechecker when
refactoring.
