Fixed ChoiceType to protect against some problem caused by treating of array.
Let's say we have the choice-form like:
```php
$form = $factory->create(ChoiceType, null, [
'choices' => [
'A',
'B',
'C',
],
'expanded' => true,
'multiple' => true,
]);
```
Then, submit data like this:
```php
$form->submit([
[], // unnecessality nested
]);
```
(Yes, I agree in most cases these situation doesn't happen, but can be)
Then, we get `array_flip(): Can only flip STRING and INTEGER values!` error at [here](6babdb3296/src/Symfony/Component/Form/Extension/Core/Type/ChoiceType.php (L114)).
Even if form is not `multiple`, annoying `Array to string conversion` error occurs in [here](6babdb3296/src/Symfony/Component/Form/ChoiceList/ArrayChoiceList.php (L144)) (via [ChoicesToValuesTransformer](5129c4cf7e/src/Symfony/Component/Form/Extension/Core/DataTransformer/ChoicesToValuesTransformer.php (L74))).
(As far as I know, non-multiple and non-expanded form has no problem, thanks to [ChoiceToValueTransformer](6babdb3296/src/Symfony/Component/Form/Extension/Core/DataTransformer/ChoiceToValueTransformer.php (L43)))
To resolve these problems, I just added a simple-validation listener to choice type.

It's currently not possible to use a custom format with `DateType` when not using one of the three values day, month or year (i.e in my case "MM/yyyy").
The formatter handles it, it looks like this option check is wrong, this PR fixes it.

# (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;
}
```

[Form] Skip CSRF validation on form when POST max size is exceeded

In #19140 the CSRF validation listener was not aware that the POST max size had exceeded, and was adding a form error message that wasn't relevant to the actual error.
This introduces the `ServerParams` utility class into the `CsrfValidationListener` and checks that the POST max size has not been exceeded. If it has then it won't bother trying to validate the CSRF token.
My main concern with this change is that it opens up an attack vector around tokens, but I've encapsulated the request size validation in a single method in `ServerParams` now so that the request handlers are using the same logic.

[Form] Consider a violation even if the form is not submitted

Hey!
I'm currently implementing an API using the form component in order to validate the payload sent (in conjonction with the FOSRestBundle). Unfortunatelly, we dig into an issue about the PATCH request which don't map some of our validation rules to the form. Basically, the violations are lost in the middle of the process.
### Use case
We have an entity with the following fields "type", "image" & "video". The field "type"can be either "default", "image" or "video" and then accordingly we use the appropriate field (none for the "default" type, video for the "video" type and image for the "image" type. Then, in our form, we change the validation groups according to our entity type in order to make the "image" field mandatory if the type is "image" and the same for the video field if the type is "video".
### Current behavior
The current behavior (since 2.5) seems to not propages a violation to a form if this form is not submitted but in our use case, changing the field "type" via a PATCH request triggers some new validation which should be reported to end user (inform that a field (video or image) is missing in the PATCH request).
### Expected behavior
The current behavior was introduced in #10567 but IMO, this update is a bug as suggested by @webmozart in https://github.com/symfony/symfony/issues/11493#issuecomment-59549054 Instead, the form component should still map validation errors to the form even if the field was not submitted. If the initial data is not valid, then your initial data was buggy from the beginning but the form should not accept it and instead of silently ignoring the errors, end users should be informed and fix it.
WDYT?

fixes#14712 and #17789.
`ChoiceType` now always use `ChoiceToValueTransformer` or
`ChoicesToValuesTransformer` depending on `multiple` option.
Hence `CheckboxListMapper` and `RadioListMapper` don’t handle
the transformation anymore.
Fixes pre selection of choice with model values such as `null`,
`false` or empty string.
