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.
