Summary:
It seems that the `close()` method that should normally be called on an object `obj` of type `java.io.Closeable` is sometimes called on `obj` of type `java.lang.Object`. It did not fully understand in which case this happens but it could be coming from a bug in Sawja since the type of `obj` in the bytecode is correct, but the Sawja reciever expression given to the Java frontend has the type `java.lang.Object`.
In any case, it does not hurt to always consider that `obj.close()` will replace the `FILE` attribute on `obj` by a `MEM` attribute.

Native compilation seems to take a couple of seconds to build the unit test
binary, but we don't need it to be native (and neither do users building infer
to install it on their machines). In fact, the test mode rebuilds it in
bytecode mode. For the sake of being able to run the unit tests when developing
on infer (and thus possibly while having some fatal warnings showing up in the
code, preventing us from building the test target), also build InferUnit in
bytecode mode.

Summary:
The Java models for resources are way to complex. The main issue I am facing with these models is that small changes in the analysis can affect the generation of the models in some weird ways. For instance, I get different specs for some of the models between my devserver and my devvm, which seems to be mostly related with the backend treatment of `instanceof`.
The objective here is to simplify the models as much as possible in order to:
1) make debugging regressions easier
2) get simpler specs and less modeled methods shipped in `models.jar`

This diff partially addresses the problem by adding a notion of "unconditional" (always owned) or "conditional" (owned if some formal at index i is owned) ownership.
Now we can handle simple examples like the one above.
I say "partially" because we still can't handle cases where there are different reasons for conditional ownership, such as
```
oneOrTwo(Obj o1, Obj o2) { if (*) return o1; else return o2; } // we won't understand that this maintains ownership if both formals are owned
Obj stillOwned = oneOrTwo(owned1, owned2);

add this profile to each maven submodule.

This diff adds a `build_mode` type (renaming the previous `build_mode` to

Currently, if we don't find `-d` or `-classes_out` on the command line then we
tell javac to redirect the compiled classes in some other directory, by default
the initial working directory. But we don't detect when these arguments are
hidden inside files (`foo` arguments on the javac command line) so the
heuristic was incomplete. Look inside these files to better tell whether we need
to make up an output directory or not.

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

Sometimes we don't want to analyze but a message gets printed that there was
nothing to analyze and we exit with error, which is confusing.

Add more debug output to be able to trace the calls to javac more easily
when --stats or --debug is passed to infer.

Summary:
This would fail before and works as expected now:
```
$ infer -- clang -c hello.c
$ cd infer-out/ && ln -s ../foo && cd ..
$ infer -- clang -c hello.c # crashes because it fails to delete infer-out/foo
```

Summary: Generalized the CppTrace into a Clang trace because we don't currently have separate checkers for Obj-C and Cpp. Happy to separate them later if there is a good reason

Summary:
Adding models that allow us to warn on unguarded accesses to subclasses of `Map`, but not on accesses of threadsafe containers like `ConcurrentMap`.
Lots more containers to model later, but stopping at `Map`s for now to make sure the approach looks ok.

Summary:
One of the tests was failing without `make clean` because infer-out didn't get
deleted when rerunning the clang db test. This was because infer thinks it's in
`Analyze` mode when capturing clang db files.

Summary:
This error message is confusing when the user is not actually running
InferPrint, eg `infer foo`: `Load Error: file foo: arguments must be .specs
files`.
With this diff, we don't get any error for `infer foo`, which is not great
either and will need to be addressed (do we support all the python arguments in
OCaml now too and are able to turn on argument parsing errors in OCaml land?).

Summary:
If we don't delete infer-out then it gets polluted with files from previous
versions of infer resulting in segfaults during `make test`.

Summary:
Module CFrontend_utils is a container for two modules: Ast_utils and General_utils.
Instead of opening CFrontend_utils in several places, it is now split into two separate modules CAst_utils and CGeneral_utils, which are now accessed directly.
