[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.

Secure unserialize by restricting allowed classes when using PHP 7

While playing around with Symfony in a PHP 7.1 application I noticed a warning in how EnvParameterResoure uses unserialize. Since PHP 7.0 introduced the options argument which allows to restrict which classes can be unserialized for better security, it might make sense to use it here. As far as I can tell this is no BC break, it only provides an additional safety mechanism.

[Yaml] Add tags support

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`.

With new changes comming to 3.3, we need a more generic reflection tracking logic than the one already managed by the autowiring subsystem.
This PR adds a new ReflectionClassResource in the Config component, and a new ContainerBuilder::getReflectionClass() method in the DI one (for fetching+tracking reflection-related info).
ReflectionClassResource tracks changes to any public or protected properties/method.
PR updated and ready, best viewed [ignoring whitespaces](https://github.com/symfony/symfony/pull/21419/files?w=1).
changelog:
* added `ReflectionClassResource` class
* added second `$exists` constructor argument to `ClassExistenceResource` - with a special mode that prevents fatal errors from happening when some parent class is broken (logic generalized from AutowiringPass)
* made `ClassExistenceResource` also work with interfaces and traits
* added `ContainerBuilder::getReflectionClass()` for retrieving and tracking reflection class info
* deprecated `ContainerBuilder::getClassResource()`, use `ContainerBuilder::getReflectionClass()` or `ContainerBuilder::addObjectResource()` instead

[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

We should log more in compiler passes - and this should be better integrated in usual log reports.
For logging more, let's drop LoggingFormatter and add a simple "log" method on ContainerBuilder.
For better integration, let's throw silenced notices - they can be caught by our Debug handler.

[DependencyInjection] Use current class as default class for factory declarations

| Doc PR | Should update the notice about the "class" attribute on http://symfony.com/doc/current/service_container/factories.html#20888 makes sense to me, considering the following sample extracted from the documentation:
```xml
<service id="app.newsletter_manager" class="AppBundle\Email\NewsletterManager">
<factory class="AppBundle\Email\NewsletterManager" method="create" />
</service>
```
The class is used as a factory to create itself, thus it can be simplified to:
```xml
<service id="app.newsletter_manager" class="AppBundle\Email\NewsletterManager">
<factory method="create" />
</service>
```
However, it's not possible to provide the same feature for the YAML format, because it doesn't allow to distinct a function from a method call if the class is not provided explicitly under the `factory` key, whereas the xml format use a dedicated `function` attribute.
Would this inconsistency between those two formats be a no-go for this feature?
The doc notices:
> When using a factory to create services, the value chosen for the class option has no effect on the resulting service. The actual class name only depends on the object that is returned by the factory. However, the configured class name may be used by compiler passes and therefore should be set to a sensible value.
If this is merged, it should be updated wisely in order to not confuse everyone with this feature when using the xml format.
UPDATE: The yaml format is now supported when the class is not provided in the factory array:
```yml
services:
my_factory:
class: Bar\Baz
factory: [~, 'create']
```
