This PR fixes bug described in #27018 issue.
I think that `getReflectionClass` should return `NULL` when internal type was used instead class name but not throws exception. As well as it does when class is empty. If someone have other opinion we can discuss it.

In several places in HttpFoundation we parse HTTP header values using a variety of regular expressions. Some of them fail in various corner cases.

Parsing HTTP headers is not entirely trivial. We must be able to parse quoted strings with backslash escaping properly and ignore white-space in certain places.

In practice, our limitations in this respect may not be a big problem. We only care about a few different HTTP request headers, and they are usually restricted to a simple values without quoted strings etc. However, this is no excuse for not doing it right :-)

This PR introduces a new utility class for parsing headers. This allows Symfony itself and third-party code to parse HTTP headers in a robust way without using complex regular expressions that are difficult to write and error prone.

We tried to do some Browsertesting with Mink and Behat, something like:

```gherkin
Scenario Outline: greet in native language

Given the browser language is "<lang>"
And I called the website
When I fill in "PHP" for "username"
And I submit the form
Then I should see "<greeting>"

	Examples:
		| lang 	| greeting 	|
		| en 	| Hello 	|
		| de 	| Hallo 	|
		| fr 	| Bonjour 	|
		| zh 	| 你好 		|
		| ru 	| привет	|
		| be 	| Bonjour 	|
```

```php
  public function theBrowserLanguageIs($arg1)
    {
        $this->getSession()->setRequestHeader('Accept', '*/*');
        $this->getSession()->setRequestHeader('Accept-Language', $arg1);
    }

```

While everything works fine with visit form submit didn't send the headers. At Mink theres also an open issue for that
https://github.com/minkphp/MinkBrowserKitDriver/issues/79

but actually the problem was between the mink browserkit and the symfony client.

This PR adds possibility to show the list of elements for a custom locale different to the current one and proposes also deprecate the `ChoiceLoaderInterface` implementation from all of them, moving it to a separate class.

See related issue #26737 for full description and use-case.

After:
```php
$formBuilder->add('country', CountryType::class, [
    'choice_translation_locale' => 'es',
]);
```

Now that services are private by default, `debug:container` should display them by default.
In fact, the public/private concept should not trigger a difference in visibility for this command.

Instead, I propose to handle service ids that start with a dot as hidden services.

PR should be ready.

(For reference, I tried using a tag instead in #26891, but that doesn't work in practice when working on the implementation.)

This PR fixed performance problem in dev mode and prevent logs serialize several times for each sub-request.

STR:
1) Install any symfony application v2.8-3.4
2) Create a simple page with 20-50 sub-requests and 5k-10k logs
3) Open page in dev mode

**Actual**
- debug toolbar not open (404 not found)
- sets of logs (in the logger debug panel) for different requests are same
- log processing takes about 20-30s
- gc also run about 50% of execution time

**Expected**
- Debug toolbar should be open
- As developer, I want to see in logger panel only those logs that are relevant to the given sub-request

### Profile and performance

Tested on page with 7k logs and 70 sub-request.

Comparison:
