Performance test in symfony-standard:
```php
<?php

use Symfony\Bundle\FrameworkBundle\Templating\TemplateNameParser;

require __DIR__.'/vendor/autoload.php';
require __DIR__.'/app/AppKernel.php';

$kernel = new AppKernel('dev', true);
$kernel->boot();
$parser = new TemplateNameParser($kernel);

$time = microtime(true);

for ($i = 0; $i < 50; ++$i) {
    $parser->parse("AcmeDemoBundle:Foo:bar$i.html.twig");
}

echo "Time:   " . (microtime(true) - $time)*1000 . "ms\n";
echo "Memory: " . memory_get_peak_usage(true)/(1024*1024) . "MB\n";
```

[Form] Deprecated bind() and isBound() in favor of submit() and isSubmitted()

| Q             | A
| ------------- | ---
| Bug fix?      | no
| New feature?  | no
| BC breaks?    | yes (*)
| Deprecations? | yes

This change was discussed for a while in #5493. **(*)** It breaks BC *only for people who implemented* `FormInterface` *manually* (not a lot, so I hope). These can fix the problem by simply renaming `bind()` and `isBound()` in their implementation to `submit()` and `isSubmitted()`.

The main rationale is that with the request handlers introduced in #6522, people won't be confronted with the term "binding" anymore. As such, `isBound()` will be a very strange name to new users that have never used `bind()` manually.

See this code sample as example:

```php
$form = $this->createForm(...);
$form->handleRequest($request);

// Imagine you have never heard about bind() or binding. What does this mean?
if ($form->isBound()) {
    // ...
}
```

In reality, `bind()` submits a form. Where-ever I renamed "bind" to "submit" in the comments, "submit" made actually much more sense. So it does in the code sample above:

```php
$form = $this->createForm(...);
$form->handleRequest($request);

// Aha!
if ($form->isSubmitted()) {
    // ...
}
```

Also when using `submit()` directly, the code makes much more sense now:

```php
$text = $this->createForm('text');
$text->submit('New Value');
```

For current users, the current naming will be supported until 3.0.

[Console] application/command as text/xml/whatever decoupling

This PR removes description generation from `Command`, `Application` and `InputDefinition` classes and delegate it to specialized descriptor classes, making it dead simple to add new output formats.

**Maybe this could include other commands, like `router:debug` or `container:debug` (see #5740)?**

- [x] Add a `DescriptorProvider` which uses `DescriptorInterface` objects to describe things.
- [x] Add `txt` descriptors.
- [x] Add `xml` descriptors.
- [x] Add `json` descriptors.
- [x] Add `md` descriptors.
- [x] Remove obsolete methods.
- [x] Repair tests.
