Summary:
As suggested by Ilya, the current message can be improved in a way that
it can contain more clear action. I also added artempyanykh's explanation at the
end of message to provide an additional justification from common sense
perspective.
But most importantly, the previous message was missing a space which is
eye bleeding, how come haven't I noticed this before, I can't stand it
OMG.

Summary:
Old versions of sawja/javalib got the line numbers slightly wrong. The workaround was to do a regexp search in the source file for the right line.
My understanding is that this is no longer necessary. This diff removes it.

Summary:
When multiple buck java tests use the same `buck-out` they sometimes fail. This isn't surprising, as they presumably clobber each other's output when running on the same files.
Since there is no reason to have this global, shared buck repo, create one for each test, inside the test directory. Also, clean up the Makefiles a bit -- they provide bogus compile targets, for example, and have mostly wrong source dependencies.
That done, remove the `testlock` crutch which enforces mutual exclusion between tests, from the buck/java tests.
I do not understand why the buck clang tests can share the global repo without failure, but there you go.

Summary:
The Eradicate backend is reporting nullable type errors, that are not always necessarily leading to null pointer exceptions.
For example, the analysis is designed to be consistent with the Java type system and report on the following code:
String foo(boolean test) {
Object object = test ? new Object() : null;
if (test) {
return object.toString(); // the analysis reports here
}
}
even though the code will not crash.
In order to make this aspect clear, this diff renames the warnings `Null Method Call` and `Null Field Access` into `Nullable Dereference`

Summary:
It's useful to test that the bucket a given error is classified as doesn't
change over time without notice.
This records the bucket for *all* the tests, even though some never produce a
bucket. This is to be on the safe size instead of risking to forget adding the
bucket information when the test changes, or when copy/pasting from a test that
doesn't have buckets to one that does.
The implementation is pretty crude: it greps the beginning of the qualifier
string for a `[bucket]`.

Summary: With the genrule approach, the directory the generated script is run from is inside `buck-out`. So we need to specify the project root before calling the `buck` command.

Summary:
This is to fix the conflicts between Eradicate and the Biabduction when reporting the same kind of errors: when Eradicate is on, the Eradicate warnings will have priority over the null deference reported by the biabduction.
If this approach proved to be successful in prod, I will refactor the reporting mechanism in the analysis itself to simply not report the null dereference in this case at all. For the codebases that aren't yet fully consistently using `Nullable`, this combined approach looks like a good way to deploy Infer toward full null safety.

Summary:
This allows Eradicate to lookup the annotations from the classpath and without requiring the code in the classpath to have been previously analyzed. The benefit is that source files can be analyzed independently of each other as long as the classpath is known.
The main goal is to run be able to run Eradicate as a linter without losing warnings.
We may have to add some more models of the standard libraries as no `Nullable` on a parameter does not necessarily mean that the method does not accept `null`.

Summary:
This makes it more obvious why infer would force a path to be absolute since we
base that decision on the resolved path. For instance:
```
$ mkdir foo
$ cd foo
$ ln -s ../examples goo
$ infer -- clang -c goo/hello.c
[...]
/home/jul/infer/examples/hello.c:14: error: NULL_DEREFERENCE
```
We see that the path is outside of the current directory clearly, whereas
before infer would report on "goo/hello.c".

Summary:
- Only generate one extra genrule for running infer. Remove all other java library rules currently being generated
- Generate infer genrule only if the `java_library` has `srcs`, otherwise there is nothing to analyze
- Use `SRCDIR` to avoid making a copy of the target sources as buck will just symlink them instead
- Added support for `android_library` rules as well
- Added support to generate both `infer` and `eradicate` genrules
