The docs state that "protected closures do not get access to the container", but this is somewhat misleading (it confused me for a quite some time). It's true that protected closures are not passed the container as a function argument, but they can access the container via `use ($app)`.

This PR was squashed before being merged into the 2.1.x-dev branch (closes #1514).

Fixed WebTestCase compatibility with PHPUnit 6+

Makes `WebTestCase` inherit from `PHPUnit\Framework\TestCase` instead of `PHPUnit_Framework_TestCase`.

Strictly speaking it's a BC break, but as the namespaced class is now available in PHPUnit 4.8.35, 5.4+ and 6.x it's probable safe.

Use PHPUnit\Framework\TestCase in Silex tests

I changed all the tests so they use the namespaced class instead of `PHPUnit_Framework_TestCase`.

That doesn't really bring anything, but will be one less thing to change when Silex switches to PHP7/PHPUnit 6.

Added WebLink component integration

I made the necessary changes to support the new WebLink component:

- `HttpKernelServiceProvider` registers the `AddLinkHeaderListener` if the component is available
- `TwigServiceProvider` adds the `WebLinkExtension` if the component and the Twig bridge are available
- Both changes are tested
- The documentation has been amended (the link to the Symfony website doesn't work as 3.3 hasn't been released yet but I believe it's the good URL)

Fix deprecation notice with symfony/twig-bridge 3.2+ in TwigServiceProvider

Fixes the deprecation triggered when instantiating `FormExtension` twig-bridge with 3.2+.

I check for the existence of `Symfony\Bridge\Twig\Extension\HttpKernelRuntime` to determine if we're using 3.2 as it was added in 3.2.0-beta1.

Fix AssetServiceProviderTest::testGenerateAssetUrl

The test broke when symfony/symfony#22528 got merged.

I added one check without the starting slash (the returned path should be relative to `base_path`) and modified the expectation of the check with the starting slash (the returned path should not be relative).

```
There was 1 failure:

1) Silex\Tests\Provider\AssetServiceProviderTest::testGenerateAssetUrl
Failed asserting that two strings are equal.

Use the simple-phpunit script in Travis and add PHP 7.1

This will fix the Travis build issues with PHP 7.

I upped the `symfony/phpunit-bridge` version requirement so we can use the `simple-phpunit` script that was added in 3.2.0, and updated the `script` config value.

While I was at it, I also added PHP 7.1 to the matrix (hopefully it's ok to do this in the same PR).

Update the documentation

Hi all!

I've made a few minor changes to the docs ~to get those back into shape.
However I could use help finishing the `routing.rst`, this describes the `RoutingServiceProvider`.
The provider is powerful and awesome, but I struggle getting any good copy in there.
So if you have time please help out :)~
