[DomCrawler] Added auto-discovery and explicit registration of namespaces in filter() and filterByXPath()

| Q | A
| --- | ---
|Bug fix: | no
|Feature addition: |yes
|Backwards compatibility break: | yes, default namespace is no longer removed in the `addContent` method
|Symfony2 tests pass: | yes|
|Fixes the following tickets: | #4845
|Todo: | -
|License of the code:| MIT
|Documentation PR: | symfony/symfony-docs#2979

* added support for automatic discovery and explicit registration of document namespaces for `Crawler::filterXPath()` and `Crawler::filter()`
* improved content type guessing in `Crawler::addContent()`
* [BC BREAK] `Crawler::addXmlContent()` no longer removes the default document namespace

I mentioned in #4845 it would probably be possible to use [DOMNode::lookupNamespaceURI()](http://www.php.net/manual/en/domnode.lookupnamespaceuri.php) to find a namespace URI by given prefix. Unfortunately we cannot use it here since we'd have to call it on a node in the namespace we're looking for.

Current implementation makes the following query to find a namespace:
```php
$domxpath->query('(//namespace::*[name()="media"])[last()]')
```

Removed old way of building icu data

Somehow these lines leaked from 2.2 while merging #9018. This needs to go to 2.3 and master.

The XPath query used was not handling descendant form elements correctly, so I fixed it and added tests for it.

Fixes this bug:
```php
$cookieJar = new CookieJar();
$cookieJar->set(new Cookie('foo', 'bar', null, '/', '.example.com'));

print_r($cookieJar->allValues('http://wwwexample.com'));
// expected result: array()
// actual result: array('foo' => 'bar')
```

**Note:** Please keep in mind that this is a first version only. Not all features (especially UX/UI-wise) that I'd like to see are in there, but it's good enough for a first merge.
