When trying to call a method on an anonymous class (with or without methods) the `UndefinedMethodFatalErrorHandler` tries to iterate `null`.

Avoid warning in PHP 7.2 because of non-countable data

Recently, the "[Counting of non-countable objects][1]" RFC was merged in PHP 7.2-dev. This means `count()` now causes a warning when passing anything that's not countable (e.g. `null` or `''`).

As PHP does not lazily execute conditions, `FormUtil::isEmtpy($data) || 0 === count($data)` will cause *both* conditions to be executed. This means `count($data)` errors when `$data` is empty.

Splitting it up in 2 statements avoids the warning being triggered in PHP 7.2.

See https://travis-ci.org/symfony-cmf/content-bundle/jobs/181815895 for a failing test caused by this bug.

Issue is easy to reproduce with test giving negative data set.
0 should not pass as supported attribute for any set of attributes but it does as in_array in the method does not use flag 'strict' set to true.

As this is abstract voter and is used by users with their code flag 'strict' should be set to true.
Since is there in 2.7 and 2.8 (LTS) IMHO it should be fixed.

b587a7294f [config] Fix issue when key removed and left value only
When a key attribute is mapped and the key is removed from the value array, if
only 'value' element is left in the array, it should replace its wrapper
array.

Assume the original value array is as follows (key attribute is 'id').

```php
array(
    'things' => array(
        array('id' => 'option1', 'value' => 'value1'),
        array('id' => 'option2', 'value' => 'value2')
    )
)
```

After normalized, the above shall be converted to the following array.

```php
array(
    'things' => array(
        'option1' => 'value1',
        'option2' => 'value2'
    )
)
```

It's also possible to mix 'value-only' and 'none-value-only' elements in
the array:

```php
array(
    'things' => array(
        array('id' => 'option1', 'value' => 'value1'),
        array('id' => 'option2', 'value' => 'value2', 'foo' => 'foo2')
    )
)
```

The above shall be converted to the following array.
```php
array(
    'things' => array(
        'option1' => 'value1',
        'option2' => array('value' => 'value2','foo' => 'foo2')
    )
)
```

The 'value' element can also be array:

```php
array(
    'things' => array(
        array(
            'id' => 'option1',
            'value' => array('foo'=>'foo1', 'bar' => 'bar1')
        )
    )
)
```
The above shall be converted to the following array.
```php
array(
    'things' => array(
        'option1' => array('foo' => 'foo1', 'bar' => 'bar1')
    )
)
```

When using VariableNode for value element, it's also possible to mix
different types of value elements:
```php
array(
    'things' => array(
        array('id' => 'option1', 'value' => array('foo'=>'foo1', 'bar' => 'bar1')),
        array('id' => 'option2', 'value' => 'value2')
    )
)
```

The above shall be converted to the following array.
```php
array(
    'things' => array(
        'option1' => array('foo'=>'foo1', 'bar' => 'bar1'),
        'option2' => 'value2'
    )
)
```

~I know there must be a lot of other places in the core where there is some repeated or useless informations in docblocks, but everytime I dig into the `Application` class, I see this, and I don't want to repeat things for consistency when adding new methods 😅  (for instance in #20808, the `setCatchThrowables / areThrowablesCaught ` methods do not need a docblock description IMHO).~

~This PR adapts docblocks where:~

- ~A docblock description is not required, as everything can be expressed in the `@return / @param` argument (the case mentioned above)~
- ~Information is redundant between description and tags, and the context does not have to be reminded again:~

    /**

The test is now completed in 3.2, but for older branch, any changes in the `YamlReferenceDumper` is not tested on travis and requires to test it manually or comment the `markTestIncomplete` line.

`assertEquals` should still be used on 3.2.

Original fix, #19813, works only when there is event dispatcher available.
This PR fix the issue also for scenario without event dispatcher.

Closes #20110 issue and #20111 PR connected to it.
Closing #17257 , as everywhere the error is converted to exception and it should be handled

# (1st) Derive "data_class" option from passed "multiple" option

Information
-------------

Following this tutorial ["How to Upload Files"][1] but storing many `brochures` instead of one, i.e.:

```php
// src/AppBundle/Entity/Product.php

class Product
{
    /**
     * @var string[]
     *
     * @ORM\Column(type="array")
     */
    private $brochures;

    //...
}
```

```php
//src/AppBundle/Form/ProductType.php

$builder->add('brochures', FileType::class, array(
    'label' => 'Brochures (PDF files)',
    'multiple' => true,
));
```

The Problem
--------------

I found a pain point here when the form is loaded again after save some brochures (Exception):

> The form's view data is expected to be an instance of class Symfony\Component\HttpFoundation\File\File, but is a(n) array. You can avoid this error by setting the "data_class" option to null or by adding a view transformer that transforms a(n) array to an instance of Symfony\Component\HttpFoundation\File\File.

The message is very clear, but counter-intuitive in this case, because the form field (`FileType`) was configured with `multiple = true`, so IMHO it shouldn't expect a `File` instance but an array of them at all events.

The PR's effect
---------------

**Before:**

```php
$form = $this->createFormBuilder($product)
    ->add('brochures', FileType::class, [
        'multiple' => true,
	'data_class' => null, // <---- mandatory
    ])
    ->getForm();
```

**After:**

```php
$form = $this->createFormBuilder($product)
    ->add('brochures', FileType::class, [
        'multiple' => true,
    ])
    ->getForm();
```

# (2nd) Return empty `array()` at submit no file

Information
-------------

Based on the same information before, but adding some constraints:

```php
// src/AppBundle/Entity/Product.php

use Symfony\Component\Validator\Constraints as Assert;

class Product
{
    /**
     * @var string[]
     *
     * @ORM\Column(type="array")
     *
     * @Assert\Count(min="1") // or @Assert\NotBlank()
     * @Assert\All({
     *     @Assert\File(mimeTypes = {"application/pdf", "application/x-pdf"})
     * })
     *
     */
    private $brochures;
}
```

This should require at least one file to be stored.

The Problem
--------------

But, when no file is uploaded at submit the form, it's valid completely. The submitted data for this field was `array(null)` so the constraints pass without any problem:

* `@Assert\Count(min="1")` pass! because contains at least one element (No matter what)
* `@Assert\NotBlank()` it could pass! because no `false` and no `empty()`
* `@Assert\File()` pass! because the element is `null`

Apart from that really we expecting an empty array instead.

The PR's effect
----------------

**Before:**

```php
// src/AppBundle/Entity/Product.php

use Symfony\Component\Validator\Constraints as Assert;

class Product
{
    /**
     * @var string[]
     *
     * @ORM\Column(type="array")
     *
     * @Assert\All({
     *     @Assert\NotBlank,
     *     @Assert\File(mimeTypes = {"application/pdf", "application/x-pdf"})
     * })
     *
     */
    private $brochures;
}
```

**After:**

```php
// src/AppBundle/Entity/Product.php

use Symfony\Component\Validator\Constraints as Assert;

class Product
{
    /**
     * @var string[]
     *
     * @ORM\Column(type="array")
     *
     * @Assert\Count(min="1") // or @Assert\NotBlank
     * @Assert\All({
     *     @Assert\File(mimeTypes = {"application/pdf", "application/x-pdf"})
     * })
     *
     */
    private $brochures;
}
```
