Find undeclared elements

[llaville]

Yesterday, in evening, I've created locally a patch in compatibility analyser to show by a U mark what elements ( class / interface / trait / user function ) are undeclared.

I've reborn an old request #137 from past !

With new API 4.0 I obtains better results with few code modified. Commit will follow soon.

It let me look also that there are some other issues I need to fix, because it gave some false positive.

Here are two examples, what it will look like :

Example 1

<?php
namespace Foo;

use Doctrine\Common\Cache\Cache;
use DateTime;

class Bar extends DateTime {
    function __construct (Cache $c) {
    }
    function foo (\Foo\Foo $foo) {
    }
}

var_dump(DateTime::ATOM);
$a = new \PDO();
$b = new \Console_Table();
$c = new \SebastianBergmann\Version("1.2");

Output :
