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:
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.

The way to replace failing tests coming from build_integration_tests.py was not
very discoverable, and now that we have a target for precisely this action we
might as well use it.
The downside is that it's much slower to run `make test-replace` that way but
that's all the more incentive to migrate tests from python to Makefiles. Anyway
most of that time is spend in the buck test, which is going to be migrated
soon.

Summary:
Summaries are modified before saving from disk, for example the attributes of the postcondition can change.
I have observed flaky reports of the internal error NULL_TEST_AFTER_DEREFERENCE. Some attributes (e.g. assigned) are changed before saving, but the spec table in memory is not changed.
So in case:
1) the procedure is analyzed on-demand, then subsequent uses in the same process use the summary in memory with the unchanged attribute, and the issue is not reported.
2) the procedure is already on disk and loaded, then the loaded summary has the changed attributes, and the issue is reported.
Flakiness happens as because of parallelism, whether a procedure is analyzed already or whether it is analyzed on-demand, can change.
The normalization function can change the instrumentation of a symbolic heap because it uses the existing comparison functions, which ignore instrumentations.
So normalization can replace part of a symbolic heap with an identical one but where the instrumentation is different — this is what I have observed.
The diff uses a different comparison function where instrumentations are taken into account.

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.
