Summary:
Eradicate currently considers a field initialized if it's simply accessed (not written to),
or initialized with another initialized field.
This fixes the issue.

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 revises the makefiles for java tests so that they are based on
the files actually produced and depended on, instead of the existing
imperative style. This is, I think, clearer and easier to modify, and
enables a little more parallelism.

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`.

Summary:This pull request adds the SuppressViewNullability annotation.
The reasoning behind this is that in libraries, one cannot use Butterknife for view binding, which forces you to do it manually. Basically, this makes a new annotation that infer treats the same way as Bind/InjectView

Summary:
Change eradicate handling of complex values so that an unknown function that
has an existing mapping to Undef is treated as if there was no existing
mapping.
Without this change, joining control-flow branches where one called a function
and the other did not resulted in a mapping to Undef. Later calls to the
function would then reuse the Undef mapping.

Summary:
Added two annotations @TrueOnNull and @FalseOnNull to be used for boolean functions to specify what value is returned when the argument is null.
Added model for TextUtils.isEmpty, which corresponds to the annotation
@TrueOnNull
static boolean isEmpty(@Nullable java.lang.CharSequence s)
Summary:
System.getProperty can return null when the property is not found, and expects a non-null argument.
Add models for Infer and Eradicate to reflect that.
Summary:
Errors arising from overriding methods defined in other files were not reported, because during parallel analysis the clusters did not have access to overridden methods, so could not load their annotation.
Changed cluster generation to add location information for the methods overridden by the procedures defined in the current cluster.
Summary:
The @NonNull annotation, with camel case, can now be used to inform Eradicate that some fields that are not initialized by the constructor can be initialized by other means, e.g. via dependency injection.
Summary:
This test was actually testing: "at least one Field not initialized error is found" where we actualy want to test "exactly one Field not initialized error is found". The case of @Inject was also missing from the tests.
