Functions declared in the same file are reported as unknown

[julienfalque]

It seems that ComposerRequireChecker isn't able to detect when called functions are declared in the same file. For example, with the following file:

<?php

namespace App;

function foo() { }

function bar() {
    foo();
}

ComposerRequireChecker will report the following error:

+----------------+--------------------+
| unknown symbol | guessed dependency |
+----------------+--------------------+
| foo            |                    |
+----------------+--------------------+

Is this the expected behavior?

I use functions a lot and this issue is quite annoying.
Looking forward to a fix, thanx.

@maglnet , @Ocramius , any plans to fix this?

@vudaltsov patches welcome: this should be easy to test, but unsure about the fix.

I don't currently have capacity to work on this project within the next few months.
