While playing with the type environment for Java, I realised that the types in models.jar where not re-generated when modifying Infer. As a consequence, some changes in Infer where surprisingly having no effect. This diff forces the type environment to be absent when analyzing the models.

This diff cleans up the detection of assertion failures in C, C++ and Objective C which was previously hacked on top of the tracing mode for Java. The code is also generalized to detect any custom errors which can be defined using the `__infer_fail` builtin, and the case of assertion failure is now just the specific case of translating `assert` using `__infer_fail` directly in the clang frontend.

Summary: public Crashes during the analysis are classified as timeouts in the .specs file. In addition, when there is a timeout, it does not say *why* the timeout occurred (hard time, symops, or recursion). This diff adds this information to the .specs file and adds a "fail hard" mode where crashes and timeouts will actually stop the analysis in developer mode (but will still be hidden in the normal production mode).

This fixes two things:
- `make -j9000` now works without crashing
- `make -C infer/src clang java` followed by `make -C infer/src clang` results
in a cached build the second time. Previously, a bug in ocamlbuild meant that
building infer/java would stomp over some files used by infer/clang, hence
infer/clang would get partially recompiled. More generally, alternating
between targets, or simply repeatedly calling `make` would result in unecessary
rebuilds.

Summary:

Infer would previously give confusing reports in the following case: two classes `foo.MyClass` defined in `MyClass.java` under directory `foo/` and `bar.MyClass` defined in file `MyClass.java` under `bar/` are compiled together in a single call to the Java compiler. Then the errors in `foo/MyClass.java` could potentially be reported in `bar/MyClass.java`, or the other way around.
The reason is: Infer starts the translation from the bytecode which only contains information about the base filename in the metadata. For example, both `foo.MyClass` and `bar.MyClass` will contains the information that the source file is `MyClass.java` but not the full path to the actual source file (hopefully).
In order to cope with this issue, this diff adds the possibility to read the package declaration from the source file so that we can map classes to the source files these classes are defined without ambiguity. In order to avoid having to open and read the source files when not necessary, the code will behave as before as long as no name conflict is found. Otherwise, it will only load and search for the package declaration when two or more sources files have the same basename but are defined in different subdirectories.

Summary:
public To deal with ObjC nullability and give meaningful error
messages, we introduced the ObjC_NULL attribute in the symbolic execution to
mean that the object carrying the attribute is null because it was the result
of a method call from a null object. However, one cannot add attributes to null,
so we had to delay nullifying the object in order to have the attribute until we
can assign it to a program variable. However, if the temp variable was used in a condition,
we were not taking into account that its meaning is null. This diff addresses that and fixes
many FPs that we have encounter.

./configure --disable-ocaml-annot
./configure --disable-ocaml-bin-annot
(the latter is more for completeness, as bin-annot are not very expensive to

`make` is 30% faster without annot files. Unless you use Eclipse you shouldn't
