### Overview
Currently, any metadata passed to `ConfigCache` (namely implementations of `ResourceInterface`) is serialized to disk. When the `ConfigCache` is validated, the metadata is unserialized and queried through `ResourceInterface::isFresh()` to determine whether the cache is fresh. That way, `ResourceInterface` implementations cannot interact with services, for example a database connection.
This PR introduces the new concept of `ResourceCheckers`. Services implementing `ResourceCheckerInterface` can be tagged as `config_cache.resource_checker` with an optional priority.
Clients that wish to use `ConfigCache` can then obtain an instance from the `config_cache_factory` service (which implements `ConfigCacheFactoryInterface`). The factory will take care of injecting resource checkers into the `ConfigCache` instance so that they can be used for cache validation.
Checking cache metadata is easy for `ResourceCheckers`:
* First, the `ResourceCheckerInterface::supports()` implementation is passed the metadata object in question. If the checker cannot handle the type of resource passed, `supports()` should return `false`.
* Otherwise, the `ResourceCheckerInterface::isFresh()` method will be called and given the resource as well as the timestamp at which the cache was initialized. If that method returns `false`, the cache is considered stale. If it returns `true`, the resource is considered unchanged and will *not* be passed to any additional checkers.
### BC and migration path
This PR does not (intend to) break BC but it comes with deprecations. The main reason is that `ResourceInterface` contains an `isFresh()` method that does not make sense in the general case of resources.
Thus, `ResourceInterface::isFresh()` is marked as deprecated and should be removed in Symfony 3.0. Resource implementations that can (or wish to) be validated in that simple manner can implement the `SelfCheckingResourceInterface` sub-interface that still contains (and will keep) the `isFresh()` method. The change should be as simple as changing the `extends` list.
Apart from that, `ResourceInterface` will be kept as the base interface for resource implementations. It is used in several `@api` interfaces and thus cannot easily be substituted.
For the Symfony 2.x series, a `BCResourceInterfaceChecker` will be kept that performs validation through `ResourceInterface::isFresh()` but will trigger a deprecation warning. The remedy is to either implement a custom ResourceChecker with a priority higher than -1000; or to switch to the aforementioned `SelfCheckingResourceInterface` which is used at a priority of -990 (without deprecation warning).
The `ConfigCache` and `ConfigCacheFactory` classes can be used as previously but do not feature checker-based cache validation.
### Outlook and closing remarks:
This PR supersedes #7230, #15692 and works at least in parts towards the goal of #7176.
The `ResourceCheckerInterface`, `...ConfigCache` and `...ConfigCacheFactory` no longer need to be aware of the `debug` flag. The different validation rules applied previously are now just a matter of `ResourceChecker` configuration (i. e. "no checkers" in `prod`).
It might be possible to remove the `debug` flag from Symfony's `Router` and/or `Translator` classes in the future as well because it was only passed on to the `ConfigCache` there.

[Form] Deprecated FormTypeInterface::getName() and passing of type instances
| Q | A
| ------------- | ---
| Bug fix? | no
| New feature? | yes
| BC breaks? | no
| Deprecations? | yes
| Tests pass? | yes
| Fixed tickets | #5321, #15008

#### Type Names
This PR deprecates the definition of the `getName()` method of form types. See #15008 for a more detailed description.
Before:
```php
class MyType extends AbstractType
{
public function getName()
{
return 'mytype';
}
// ...
}
```
After:
```php
class MyType extends AbstractType
{
// ...
}
```
You should always reference other types by their fully-qualified class names. Thanks to PHP 5.5, that's easy:
Before:
```php
$form = $this->createFormBuilder()
->add('name', 'text')
->add('age', 'integer')
->getForm();
```
After:
```php
$form = $this->createFormBuilder()
->add('name', TextType::class)
->add('age', IntegerType::class)
->getForm();
```
#### Type Instances
Furthermore, passing of type instances is deprecated.
Before:
```php
$form = $this->createForm(new AuthorType());
```
After:
```php
$form = $this->createForm(AuthorType::class);
```
#### DIC Aliases
When registering a type in the DIC, you should omit the "alias" attribute now.
Before:
```xml
<service id="my.type" class="Vendor\Type\MyType">
<tag name="form.type" alias="mytype" />
<argument type="service" id="some.service.id" />
</service>
```
After:
```xml
<service id="my.type" class="Vendor\Type\MyType">
<tag name="form.type" />
<argument type="service" id="some.service.id" />
</service>
```
Types without dependencies don't need to be registered in the DIC as they can be instantiated right away.
#### Template Block Prefixes
By default, the class name of the type in underscore notation minus "Type" suffix is used as Twig template block prefix (e.g. `UserProfileType` => `user_profile_*`). If you want to customize that, overwrite the new `getBlockPrefix()` method in your type:
```php
class UserProfileType extends AbstractType
{
public function getBlockPrefix()
{
return 'profile';
}
// ...
}
```
