Summary:
On wrong arguments (or on no arguments at all), `infer` would spew the error
message of `infer.py`, which makes no sense. Make the python code swallow error
messages and exit with a special code on errors coming from command line
parsing so that the OCaml side is in charge of printing usage messages.

Summary:
Adding a new mode linters. Now if the analyzer is linters, we do the linters and don't translate,
then, if the analyzer is Infer, we do the translation and the backend and not the linters checks, and the
default is that we do capture, backend and lint checks.
Made the tests separated, which saves time and also shows that the linters mode works.

Summary:
Since clang -### can silently return nothing when passed bogus arguments (eg,
trying to compile a non-existent file), run the original command in that case
in case it's a genuine error. This prevents puzzling behaviours such as
`infer -- clang -c bogus_file.c` succeeding with 0 files analyzed.

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
left for the future.

Use the output of `clang -###` to drive which commands to run. Attach the plugin to all commands starting with `-cc1`.
Benefits:
- support for compiling multiple files in one clang command, eg `infer -- clang -c file1.c file2.c`
- support for compile commands that do not target a `.o` file, eg `infer -- clang -S hello.c`
- support for `-cc1` compile commands
- more generally, run all commands that clang would run, and attach plugin in all compilation cases

Also move the list of checks disabled by default into config.ml for better

Simplifies the way to configure cmake to run infer's fake compiler commands.
Instead of `CC=/path/to/infer/infer/lib/capture/clang cmake .`, which is what
is advised on #25 and is now outdated because the paths to infer's clang has
changed since, simply run `infer -- cmake .`. The only caveat is that infer
tries to analyze the end result, and prints "No issues found". This could be
fixed later.
