Summary:
Infer prepends the directory containing the ananotation processor and
the current working directory to the classpath javac option. This diff
enables prepending these to the classpath when it is passing in an args
file (as the classpath can get too long to pass on the command line).

Summary:
Add a module target to the src Makefile that builds a single module and
its dependencies, perhaps with extra flags. Useful for generating
assembly or interfaces, as well as directing the typechecker when
refactoring.
Execute: `make INFER_CFLAGS=<flags> M=<Module>.cm{o,x} module`

Summary:
The philosophy of the tracing mode reporting is to not report the errors in a method if reaching this error does depend on information that can be false at call site. Typically with:
void foo(Object obj, int x) {
if (x == 3) {
obj.toString();
}
}
it may be that we always call `foo` with a non-null parameter or `x != 3`.
Thechnically, the reporting code matches the pairs of the form (precondition, error) and filtering out the cases where the precondtions was not imposing constraints on the calling context, and report the other cases. So the NPE could be reported in the following case:
void bar() {
foo(null, 3);
}
However, we were missing the case where there was anyway no way to call a method in a safe way, i.e. all the preconditions were of the form: (precondition, error), for example:
void baz(boolean b) {
if (b) {
foo(null, 3);
} else {
foo(null, 3);
}
}
In that case, the summary is of the form
PRE (1): b = false
POST: NullPointerException
PRE (2): b = true
POST: NullPointerException
In which case it is legit to report `NullPointerException` in `baz`.

Summary:
As suggested in the discussion https://github.com/facebook/infer/issues/326 this pull request implements
```ocaml
get_overriden_method : Tenv.t -> Procname.java -> Procname.t
```
to get the method of a superclass that is being overridden by a specific java pname.
I thought of unit test this, but unfortunately I wasn't able to figure out how to create the proper context with OUnit2. Perhaps the easiest way to test this will be integration tests.
Feel free to reject the pull request if unit tests are mandatory (or for any other reason, of course).

Summary:This enables controlling the encoding chosen by infer via the usual environment
variables. For instance:
```
LC_ALL="C" infer ... # sets LOCALE to "ascii"
LC_ALL="en_US.UTF-8" infer ... # sets LOCALE to "UTF-8"
```
This gives an easy solution to #320: run `LC_ALL="en_US.UTF-8" infer ...`.
Right now the only solution is to edit the Python scripts by hand instead!
