Summary:
This will help porting more Python code over to OCaml. Since the reporting step
uses a lot of Python libraries that would be a pain to rewrite in OCaml (eg,
syntax highlighting), keep this functionality in Python and make it possible to
call it from OCaml as a script.

Summary:
Record an abstraction of the bug traces in the tests. The abstraction of a
trace is the sequence of descriptions. In practice, descriptions are either
empty, or of the form "start/end/return from/call to procedure X". They seem
pretty stable.
Motivation: there is nothing testing the traces reported by Infer right now,
even though they are surfaced to developers. For instance, Quandary uses
--issues-txt instead of --issues-tests to make sure the traces do not regress.
This change would make this approach more widespread.

Summary:
- rename java.make -> javac.make, config.make -> java.make, and move to infer/tests/ so it's easier to use from infer/tests/build_systems/
- use these from ant's test Makefile, much code reuse!
- factor out common functionality between java and clang
A wrinkle: sorting is now done the same way for --issues-tests and
--issues-txt, which produces bogus (but still as deterministic) sorting for
--issues-txt. This is more of a cosmetic issue, but I hope to fix it in a later
diff that gets rid of calls to `sort` in favour of sorting directly from
`InferPrint`.

Our patch to Javalib has been accepted, so we can parse programs with invokedynamic!
invokedynamic still crashes Sawja, but I have worked around this by replacing all invokedynamic's with invokestatic's before passing them to Sawja.
This means we can handle everything about invokedynamic except calling the correct function (I call a dummy function with the correct signature for now).
We can try to actually call the right method in the future.

Summary:
This adds generic support for reporting error traces as usual infer issues
traces (instead of putting them in the textual description of the error) to
Trace.ml and SinkTrace.ml.
The siof checker is made to use these new traces, and gets an improved error
message mentioning the name of the problematic global as well, which requires a
slight API change in Pvar.re.
The support in Trace.ml is incomplete: passthroughs are ignored. This missing
feature will be needed by Quandary to migrate its error messages.

Summary:
- set SHELL to bash explicitly in Makefiles (Debian uses dash)
- avoid using system headers when using our own clang's headers in tests
- do not rely on the name of the object file to write the frontend debugging scripts. It turns out that `-o` is *not* always present in the arguments of `-cc1` functions so the `Option.get` could crash. Since we don't actually need to get the object file name, just a nice enough name, don't try to be smarter at guessing what object will be created and pick a different name built from the source name instead.
