PyCG can't support the analysis of function pointers in a call graph.

Hi,

It's a great project. But I've encountered an issue where PyCG cannot handle function pointers in the code.

Here's an example:

# pycg_test.py
def test1():
    print("test1")

class Foo():
    def __init__(self, name=None, fp=None):
        self.name = name
        self._handler = fp or test1

    def test2(self):
        self._handler()

c = Foo()
c.test2()

The minimum expected result for test2 should be: "pycg_test.Foo.test2": ["pycg_test.Foo._handler"]. If higher requirements are needed, it should extend to the following fp and test1, i.e., "pycg_test.Foo.test2": ["pycg_test.Foo._handler", "pycg_test.test1"].

However, the current output from PyCG is insufficient:

$ pycg pycg_test.py
{"pycg_test": ["pycg_test.Foo.__init__", "pycg_test.Foo.test2"], "pycg_test.test1": ["<builtin>.print"], "<builtin>.print": [], "pycg_test.Foo.__init__": [], "pycg_test.Foo.test2": []}

I want to ask if there's any solution available. I'm also willing to provide a PR. Thank you!
