I realized while implementing my own `ArgumentValueResolver` that registering a new one is not easy, you have to give the whole list of resolver instead of pushing your one in the stack.

- map VERBOSITY_QUIET normally, rather than suppressing all output
  without override

- ensure that we do write to the output if we've determined (via
  verbosityLevelMap) that we should

About the second point, it seems ConsoleLogger has the same issue (https://github.com/symfony/symfony/blob/2.8/src/Symfony/Component/Console/Logger/ConsoleLogger.php#L92), but since we're not using that, I haven't checked it.

[Routing] Throw exception when PHP start tag is missing

The Problem
---

In the documentation, we never use the PHP start tag. However, in the first tutorials, people simply copy/past the code examples, save the file and expect things to work. They seem to often forget to add the PHP start tag.

Without start tag, the annotation file loader simply skips the file without providing any reason why. As a big framework is quite overwhelming, simple things like this are completely forgotten.

The Fix
---

If a `*.php` file only consists of `T_INLINE_HTML`, it means there is no `<?php` start tag. In this case, instead of skipping the file, an exception is throwed with a possible fix.

BC Break?
---

As the file loader is only executed for `*.php` files, I think the BC break is minimal, but it is possible that people have applications with `*.php` files *without* a start tag. If this file lives in a routing loaded directory (e.g. when doing `@AppBundle/Controller`), it would now result in an exception.

I think this BC break is minimal and can be ignored. If you don't agree, we can add a little str match to check if `class ... {` exists. If that's the case, I think it's safe to say that it was meant to be a PHP file.

Bug or Feature?
---

I don't know if this is considered a bug or a feature, so I submitted it as a feature.

This adds the ability to dump a specific bundle config option from the `debug:config` command.

For instance `debug:config StofDoctrineExtensionsBundle uploadable` gives:

![](http://image.prntscr.com/image/b78953dbe34c4efd817bb6f831ddd0ba.png)

I hesitated to just look for a `.` in the `name` argument rather than adding a `path` argument that doesn't include the bundle alias (that is took from the first argument of the command), let me know what you think about that.

- [x] Getting someone to test on Windows as exception might differ from symlink functionality

## Why
Symlinks are good for directories, but for files hardlinks are sometime a better match when needing to represent same file in several locations.

One use case for this feature is for multi tagging of Http Cache when running against FileSystem. Multi tagging is used in FoSHttpCache and supported when running Varnish, but not with Symfony HTTPCache, yet.. With hardlinks combined with meta information containing tags within the file, lookup and reverse lookup is thus easily possible.

## What
Introduces method `hardlink()` with similar behavior as `symlink`, difference being:
- Allowing several targets to be provided to match use case in 'why'
- Like `symlink` removes existing target if not the same, but uses `fileinode` to compare target & source

When writing the `ControllerArgumentValueResolverPass`, I needed a sorting on `priority`. I ended up copying a method from another class. I noticed this was done more often and 99% of the code was the same. I've moved the most common notation into the trait and "used" the trait in the priority aware passes. This increases horizontal re-use and means people can also use this in their bundles.

The cases that were slightly different, are still working completely. I had to fix some tests because they returned an invalid value from the mocked find method.

While building a software to extract information from a webpage, I need to fill a form with hints on the fields labels.

Example:

```html
<form>
   ...
   <label for="my_field">Input the result of 3 + 4:</label>
   <input type="text" id="my_field" name="my_field" />
   ...
</form>
```

 I thought it would be handy to have the field labels attached to each field.
So given the previous form you could now do:

```php
$form->get('my_field')->getLabel()->textContent;
```

This PR uses the new `ArgumentResolver` to inject a security user when the signature implies so. This is based on the [docs code example](symfony/symfony-docs#6438 (comment)) and [existing pr on the SFEB](sensiolabs/SensioFrameworkExtraBundle#327).

With the new example you can do the following:
```php
// when a User is mandatory, e.g. behind firewall
public function fooAction(UserInterface $user)

// when a User is optional, e.g. where it can be anonymous
public function barAction(UserInterface $user = null)
```
This deprecates the `Controller::getUser()` method.

I have added it on a priority of 40 so it falls just under the `RequestValueResolver`. This is because it's already used and the initial performance is less of an impact.

There was a comment asking if the `controller_argument.value_resolver` tag name wasn't too long. If decided this tag should change before 3.1 is released, I will update it in here.

*`RequestValueResolver` contains a small codestyle consistency fix.*

Add support for setter injection in the Dependency Injection Component.

Setter injection should be avoided when possible. However, there is some legitimate use cases for it. This PR follows a proposal of @weaverryan to ease using [DunglasActionBundle](https://github.com/dunglas/DunglasActionBundle) with symfony#16863. The basic idea is to include a setter for the required service in the trait and let the DependencyInjection Component autowire the dependency using the setter.

This way, a newcomer can use the trait without having to create or modify the constructor of the action.
