This PR removes the need to call `$this->iniSet('error_reporting', -1 & ~E_USER_DEPRECATED);` in tests that are already tagged as legacy. We needed them while drafting our deprecation policy, but that's only burden to me now.
This PR also fixes the way we detect if phpunit is running the test suite for projects that have phpunit in their composer.json's require-dev

Automatically start server:run if server:start failed
After this PR, `server:start` will ask the user if it wants to start `server:run` automatically. If yes, the `server:run` command is executed and the server is started. If no, the command exits with `1`.
Example of Yes:
```
$ php app/console server:start
This command needs the pcntl extension to run.
You can either install it or use the server:run command instead to run the built-in web server.
Do you want to start server:run immediately? [Yn]
Server running on http://127.0.0.1:8000
Quit the server with CONTROL-C.
```
Example of No:
```
$ php app/console server:start
This command needs the pcntl extension to run.
You can either install it or use the server:run command instead to run the built-in web server.
Do you want to start server:run immediately? [Yn] n
$ ...
```
I've created this PR, because documentation currently still has to promote `server:run` to be safe. You don't want to tell people, "use `server:start`" and have them getting an error immediately (please note that starting the server is probably the first action with Symfony). Example: https://github.com/symfony/symfony-demo/pull/17

Description
---
This PR adds some visual and textual information about the Symfony version that is currently used. It'll indicate when the used version has reached eom or eol. I hope this will make people more aware of the fact that they should update (as I've seen quite some people using completely outdated Symfony versions).

configure the format of both numbers and dates as well as timezones
without the need to write custom code.
For example, using the new configuration options can look like this:
```yaml
twig:
date:
format: d.m.Y, H:i:s
interval_format: %%d days
timezone: Europe/Berlin
number_format:
decimals: 2
decimal_point: ,

As discussed, after updating the first console commands to the new style guide, we were going to introduce the needed tweaks. This PR is the first one with those tweaks.
### Tables
Headers now are displayed in the usual green color used frequently by Symfony commands:
### Command tiles and section titles
I see these titles in a beautiful blue color ... but lots of people use color schemes which make them almost unreadable. Now they use the yellow color frequently used by Symfony commands:
### Listings
Elements in a listing no longer add an extra blank line. See #14174 for the rationale.

According to https://github.com/Seldaek/monolog#log-levels
the level `NOTICE` means "Normal but significant events".
So when a PHP notice occurs, it's not a "normal" event,
but an error.
That's why all PHP errors should use at least the `WARNING` error
level.

This PR uses the parameters "locale" and "fallback_locales" to generate the catalogues at warmup, avoiding the creation of files at runtime.
Commits

94d3876FIX#13919 added TranslationsCacheWarmer to generate catalogues at warmup
The word 'movies' was singularified to 'movy'. There seem to be only two
words ending in 'ovies', which are 'movies' and 'anchovies'. The singular
of the latter is 'anchovy'. All other words ending in 'vies' singularify to
'vy', so the word 'movies' is an exception to the general rule.
According to https://github.com/Seldaek/monolog#log-levels
the level `NOTICE` means "Normal but significant events".
So when a PHP notice occurs, it's not a "normal" event,
but an error.
That's why all PHP errors should use at lease the `WARNING` error
level.

The fix for IE8 which does not have the addEventListener method on

checking the existence on the wrong object. It is a method on the

I implemented the additional options "choice_label", "choice_name", "choice_value", "choice_attr", "group_by" and "choices_as_values" for ChoiceType. Additionally the "preferred_choices" option was updated to accept callables and property paths.
The "choices_as_values" option will be removed in Symfony 3.0, where the choices will be passed in the values of the "choices" option by default. The reason for that is that, right now, choices are limited to strings and integers (i.e. valid array keys). When we flip the array, we remove that limitation. Since choice labels are always strings, we can also always use them as array keys:
```php
// Not possible currently, but possible with "flip_choices"
$builder->add('attending', 'choice', array(
'choices' => array(
'Yes' => true,
'No' => false,
'Maybe' => null,
),
'choices_as_values' => true,
));
```
All the features described here obviously also apply to subtypes of "choice", such as "entity".
**choice_label**
Returns the label for each choice. Can be a callable (which receives the choice as first and the key of the "choices" array as second argument) or a property path.
If `null`, the keys of the "choices" array are used as labels.
```php
// callable
$builder->add('attending', 'choice', array(
'choices' => array(
'yes' => true,
'no' => false,
'maybe' => null,
),
'choices_as_values' => true,
'choice_label' => function ($choice, $key) {
return 'form.choice.'.$key;
},
));
// property path
$builder->add('attending', 'choice', array(
'choices' => array(
Status::getInstance(Status::YES),
Status::getInstance(Status::NO),
Status::getInstance(Status::MAYBE),
),
'choices_as_values' => true,
'choice_label' => 'displayName',
));
```
**choice_name**
Returns the form name for each choice. That name is used as name of the checkbox/radio form for this choice. It is also used as index of the choice views in the template. Can be a callable (like for "choice_label") or a property path.
The generated names must be valid form names, i.e. contain alpha-numeric symbols, underscores, hyphens and colons only. They must start with an alpha-numeric symbol or an underscore.
If `null`, an incrementing integer is used as name.
```php
// callable
$builder->add('attending', 'choice', array(
'choices' => array(
'Yes' => true,
'No' => false,
'Maybe' => null,
),
'choices_as_values' => true,
'choice_name' => function ($choice, $key) {
// use the labels as names
return strtolower($key);
},
));
// property path
$builder->add('attending', 'choice', array(
'choices' => array(
'Yes' => Status::getInstance(Status::YES),
'No' => Status::getInstance(Status::NO),
'Maybe' => Status::getInstance(Status::MAYBE),
),
'choices_as_values' => true,
'choice_name' => 'value',
));
```
**choice_value**
Returns the string value for each choice. This value is displayed in the "value" attributes and submitted in the POST/PUT requests. Can be a callable (like for "choice_label") or a property path.
If `null`, an incrementing integer is used as value.
```php
// callable
$builder->add('attending', 'choice', array(
'choices' => array(
'Yes' => true,
'No' => false,
'Maybe' => null,
),
'choices_as_values' => true,
'choice_value' => function ($choice, $key) {
if (null === $choice) {
return 'null';
}
if (true === $choice) {
return 'true';
}
return 'false';
},
));
// property path
$builder->add('attending', 'choice', array(
'choices' => array(
'Yes' => Status::getInstance(Status::YES),
'No' => Status::getInstance(Status::NO),
'Maybe' => Status::getInstance(Status::MAYBE),
),
'choices_as_values' => true,
'choice_value' => 'value',
));
```
**choice_attr**
Returns the additional HTML attributes for choices. Can be an array, a callable (like for "choice_label") or a property path.
If an array, the key of the "choices" array must be used as keys.
```php
// array
$builder->add('attending', 'choice', array(
'choices' => array(
'Yes' => true,
'No' => false,
'Maybe' => null,
),
'choices_as_values' => true,
'choice_attr' => array(
'Maybe' => array('class' => 'greyed-out'),
),
));
// callable
$builder->add('attending', 'choice', array(
'choices' => array(
'Yes' => true,
'No' => false,
'Maybe' => null,
),
'choices_as_values' => true,
'choice_attr' => function ($choice, $key) {
if (null === $choice) {
return array('class' => 'greyed-out');
}
},
));
// property path
$builder->add('attending', 'choice', array(
'choices' => array(
'Yes' => Status::getInstance(Status::YES),
'No' => Status::getInstance(Status::NO),
'Maybe' => Status::getInstance(Status::MAYBE),
),
'choices_as_values' => true,
'choice_value' => 'htmlAttributes',
));
```
**group_by**
Returns the grouping used for the choices. Can be an array/Traversable, a callable (like for "choice_label") or a property path.
The return values of the callable/property path are used as group labels. If `null` is returned, a choice is not grouped.
If `null`, the structure of the "choices" array is used to construct the groups.
```php
// default
$builder->add('attending', 'choice', array(
'choices' => array(
'Decided' => array(
'Yes' => true,
'No' => false,
),
'Undecided' => array(
'Maybe' => null,
),
),
'choices_as_values' => true,
));
// callable
$builder->add('attending', 'choice', array(
'choices' => array(
'Yes' => true,
'No' => false,
'Maybe' => null,
),
'choices_as_values' => true,
'group_by' => function ($choice, $key) {
if (null === $choice) {
return 'Undecided';
}
return 'Decided';
},
));

'No' => Status::getInstance(Status::NO),
'Maybe' => Status::getInstance(Status::MAYBE),
),
'choices_as_values' => true,
'group_by' => 'type',
));
```
**preferred_choices**
Returns the preferred choices. Can be an array/Traversable, a callable (like for "choice_label") or a property path.
```php
// array
$builder->add('attending', 'choice', array(
'choices' => array(

**Technical Changes**
To properly implement all this, the old `ChoiceListInterface` class was deprecated and replaced by a new, slimmer one. The creation of choice views is now separated from choice lists. Hence a lot of logic is not executed anymore when processing (but not displaying) a form.
Internally, a `ChoiceListFactoryInterface` implementation is used to construct choice lists and choice views. Two decorators exist for this class:
* `CachingFactoryDecorator`: caches choice lists/views so that multiple fields displaying the same choices (e.g. in collection fields) use the same choice list/view
* `PropertyAccessDecorator`: adds support for property paths to a factory
**BC Breaks**
The option "choice_list" of ChoiceType now contains a `Symfony\Component\Form\ChoiceList\ChoiceListInterface` instance, which is a super-type of the deprecated `ChoiceListInterface`.
