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`.

Summary:
Instead of the custom filtering done by `InferPrint --issues-tests`, use the
filtering done by `infer` and run without filtering for our e2e tests. We still
test the filtering for our build systems integration tests, and this diff
restores that behaviour for the ant test (hence the bugs removed from
ant/issues.exp).
Also add internal exceptions to most tests to get more signal out of them (eg,
knowing when we add assertion failures and the like).
Retire the old `--issues-tests` to limit the number of ways we do filtering.

Summary:
This diff converts the Eradicate and Checkers tests to the new direct test format, which does not rely on buck or junit.
A self-contained Makefile is used to compile and analyze the test files, including all the dependencies, and a special option in InferPrint is used to produce a file of expected results `issues.exp`, which is checked into the repository.
Having an explicit Makefile makes it easy to edit and compile one set of test files in isolation, to investigate test failures, do debugging, etc.
A bunch of boilerplate code is removed. For example, the single file of expected results `issues.exp` replaces the 1.5K LOC in `endtoend/java/eradicate`.

Before this diff, the checker was collecting in a bottom-up fashion all possible call trees from `PerforamanceCritical`-annotated methods to `Expensive`-annotated ones. With this diff, we just collect the names of the direct transitively expensive callees and compute the expensive call stacks when reporting errors only.

Summary:public
Is seems that automatically inheriting annotations like `PerformanceCritical` or `NoAllocation` is the right thing to do in general. Otherwise, we need to enforce sub-typing rules which in the best case just adds a little bit of documentation, but could miss important issues when the code is not fully annotated. I am simplifying this part to avoid adding boilerplate code for the `NoAllocation` case.

This is an initial version of the Expensive checker which only report violations on direct calls. The main objective is to setup all the files for this new checker.
The next steps are:
1) run the checker in interprocedural mode
2) Save in the summary of a method foo() the annotation attribute Expensive if a direct callee of foo is annotated with Expensive
3) Check that Expensive is enforced by subtyping, i.e. check that non-expensive method cannot be overwritten by a method annotated with Expensive
