This PR introduces named arguments for services definitions. It's especially useful to inject parameters in an autowired service. It is (at least partially) an alternative to #21376 and #20738.
Usage:
```yml
services:
_defaults: { autowire: true }
Acme\NewsletterManager: { $apiKey: "%mandrill_api_key%" }
# Alternative (traditional) syntax
services:
newsletter_manager:
class: Acme\NewsletterManager
arguments:
$apiKey: "%mandrill_api_key%"
autowire: true
```
```php
use Doctrine\ORM\EntityManager;
use Psr\Log\LoggerInterface;
namespace Acme;
class NewsletterManager
{
private $logger;
private $em;
private $apiKey;
public function __construct(LoggerInterface $logger, EntityManager $em, $apiKey)
{
$this->logger = $logger;
$this->em = $em;
$this->apiKey = $apiKey;
}
}
```

[DI] Add prototype services for PSR4-based discovery and registration

Talking with @dunglas, we wondered if this could be a good idea, as a more general approach to folder-based service registration as done in [DunglasActionBundle](https://github.com/dunglas/DunglasActionBundle/blob/master/DependencyInjection/DunglasActionExtension.php).
So here is the implementation.
This allows one to define a set of services as such:
```yaml
services:
App\:
resources: ../src/{Controller,Command} # relative to the current file as usual
autowire: true # or any other attributes really
```
This looks for php files in the "src" folder, derivates PSR-4 class names from them, and uses `class_exists` for final discovery. The resulting services are named after the classes found this way.
The "resource" attribute can be a glob to select only a subset of the classes/files.
This approach has several advantages over [DunglasActionBundle](https://github.com/dunglas/DunglasActionBundle/blob/master/DependencyInjection/DunglasActionExtension.php):
- it is resilient to missing parent classes (see test case)
- it loads classes using the normal code path (the autoloader), thus play well with them (e.g. if one registered a special autoloader).
- it is more predictable, because it uses discovered paths as the only source of ids/classes to register - vs relying on `get_declared_classes`, which would make things context sensitive.
Fits well with current initiatives to me.

This PR adds custom tags support to the Yaml component.
Symfony tags (`!!binary`, `!str`, etc.) are still managed in the parser to have a lighter diff but we'll be able to convert them later if we want to.
The primary addition of this PR is the `TagInterface`:
```php
interface TagInterface
{
public function construct(mixed $value): mixed;
}
```
It can be used to register custom tags. An example that could be used to convert [the syntax `=iterator`](https://github.com/symfony/symfony/pull/20907#issuecomment-270728216) to a tag:
```php
final class IteratorTag implements TagInterface
{
public function construct(mixed $value): mixed
{
return new IteratorArgument($value);
}
}
$parser = new Parser(['iterator' => new IteratorTag()]);
```
If you think this is too complex, @nicolas-grekas [proposed an alternative](https://github.com/symfony/symfony/issues/21185#issuecomment-271074840) to my proposal externalizing this support by introducing a new class `TaggedValue`.

[DI] Allow to count on lazy collection arguments

When using the new iterator feature of the DI component to lazy load collection, we always know the number of arguments in the collection (only the invalidBehavior set to `IGNORE_ON_INVALID_REFERENCE` may change this number). So we are able to generate and use a `RewindableGenerator` implementing `\Countable` by computing this value ahead.
So, in a service accepting `array|iterable`, like in the `GuardAuthenticationListener` (see #21450):
```php
class GuardAuthenticationListener implements ListenerInterface
{
private $guardAuthenticators;
/**
* @param iterable|GuardAuthenticatorInterface[] $guardAuthenticators The authenticators, with keys that match what's passed to GuardAuthenticationProvider
* @param LoggerInterface $logger A LoggerInterface instance
*/
public function __construct($guardAuthenticators, LoggerInterface $logger = null)
{
// ...
}
public function handle(GetResponseEvent $event)
{
if (null !== $this->logger) {
$context = array()
if (is_array($this->guardAuthenticators) || $this->guardAuthenticators instanceof \Countable) {
$context['authenticators'] = count($this->guardAuthenticators);
}
$this->logger->debug('Checking for guard authentication credentials.', $context);
}
// ...
}
}
```
we still keep the ability to call count without loosing the lazy load benefits.

Getter overriding by the container will allow a new kind of dependency injection which enables easier laziness and more immutable classes, by not requiring any corresponding setter. See linked issue for more.
This is WIP:
- [x] wire the concept
- [x] dump anonymous classes with PhpDumper
- [x] generate at runtime in ContainerBuilder::createService
- [x] tests
- [x] make it work on PHP 5

[DI] Add Yaml syntax for short services definition

In my experience, most (at least, a lot) of the service definitions in an end-application only require the class and constructor arguments.
#21133 allows to get rid of the `class` attribute by using the service id.
Which means only arguments remain for most use-cases. Hence, we could support this syntax:
#### Before:
```yml
services:
App\Foo\Bar:
arguments: ['@baz', 'foo', '%qux%']
```
#### After:
```yml
services:
App\Foo\Bar: ['@baz', 'foo', '%qux%']
```
It works especially well along with services `_defaults` introduced in #21071 :
```yml
services:
_defaults:
public: false
autowire: ['set*']
tags: ['serializer.normalizer']
App\Serializer\FooNormalizer: ['@baz', 'foo', '%qux%']
```

[DI] Factorize compiler passes around new AbstractRecursivePass

This PR introduces an AbstractRecursivePass that is able to visit the definition tree recursively everywhere a Definition or a Reference can be nested.
All existing compiler passes that need recursivity are updated to leverage this new class.
This remove a bunch of boilerplate that was previously repeated all over.
It also fixes compiler passes that eg missed looking at configurators for no reason (this "fix" is a new feature really).
It then applies recursivity to AutowirePass, that does not handle it today, but should.
I'm happy that the net result is a loss of 153 lines :)

For synthetic services, the generated methods are just dead code to fill opcache ;)
And having them in "methodMap" prevents using the property for checking if a service comes from a (non-synthetic) definition or not.
This prepares some changes that we'd like to do in 4.0, see #19668.

Helps a bit on https://rawgit.com/kocsismate/php-di-container-benchmarks/master/var/benchmark.html
note: if we want more performance, we should consider deprecating case insensitivity of service identifiers.
