Summary:
InferClang knows what to do if its name ends in ++. So it is not
necessary to pass whether or not the original clang executable ended in
++ to InferClang using the the INFER_XX environment variable. Instead,
create an InferClang++ symbolic link and make the clang wrapper call
either InferClang or InferClang++ as needed.

Summary:
During the incremental analysis using the Buck distributed cache, if there is a cache hit for a given module, the output jars for the intermediate targets are not necessarily dowloaded. We therefore need to filter the jar files that are present on disk before loading the analysis artifacts from it.

Summary:
Before this diff, Infer was simply going through the list of jar files found in `buck-out` and was loading all the `report.json` files found in those jar files in order to merge them into a final report. The main drawback of this was that removing `buck-out` was mandatory to get accurate results when switching between targets to analyze.
With this diff, we now use the `buck audit classpath` option to get from a list of targets, the list of jar files to load the `report.json` files from. This allows to more easily use Infer from the command line when switch branches from the repositories or when switching between targets to analyze.

Summary: The reactive mode is not currently supported for Java Buck projects. Print a clear error message to avoid confusion. Using `--reactive` with Buck projects is crashing. When using reactive, the backend crashes because it tries to find the `.start` file in `infer-out` whereas Infer saves the analysis artifacts next to the generated classes following the `-d` options with Buck so that they can be cached. Pointing the backend to the right Infer out would not help as this directory will be blown up as soon as the files are modified.

Summary:
This diff changes the toplevel 'infer' executable from the current
python script to an OCaml binary. Currently this executable only parses
command line arguments, sets up environment variables, and invokes the
existing python script. This improves infer's command-line and
configuration interface, since passing arguments to the frontends or
backend no longer requires manually setting environment variables, and
arguments for the toplevel can now also be specified in .inferconfig.
Simplification and migration of functionality from the python script is
