This will stop Infer from creating an `infer-out` directory when just running `infer`.
(I run `infer` without any arguments somewhat often to look at documenting.)
One downside to this is that there will be no logs when running Infer without any commands - is this bad?

- `make -C infer/src clang java` followed by `make -C infer/src clang` results

building infer/java would stomp over some files used by infer/clang, hence
infer/clang would get partially recompiled. More generally, alternating

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.

mean that the object carrying the attribute is null because it was the result

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.
