[Form] Fixed show float values as choice value in ChoiceType

There is a closed [issue][1] related to this before Symfony 2.7 (when choice value still was the key from the `array`). This issue already happened in 2.7+ but now inside Symfony core.
Information
-----------
[This method][3] checks whether the given choices can be cast to strings without generating duplicates (3ab8189080 in #16705):
```php
private function castableToString(array $choices, array &$cache = array())
{
foreach ($choices as $choice) {
if (is_array($choice)) {
if (!$this->castableToString($choice, $cache)) {
return false;
}
continue;
} elseif (!is_scalar($choice)) {
return false;
} elseif (isset($cache[$choice])) { // <---- red breakpoint
return false;
}
$cache[$choice] = true; // <---- red breakpoint
}
return true;
}
```
So it should to keep [scalar values (integer, float, string or boolean)][2] as choice values always (unless have duplicates values).
The Problem
-----------
But in this situation it doesn't happen:
```php
$form = $this->createFormBuilder()
->add('foo', ChoiceType::class, [
'choices' => [
'Min' => 0.5,
'Mid' => 1.0,
'Max' => 1.5,
]
])
->getForm();
```
**Output:**
```html
<select id="form_foo" name="form[foo]">
<option value="0">Min</option>
<option value="1">Mid</option>
<option value="2">Max</option>
</select>
```
[**Why?**][5]
If the key of the array is a float number, it's interpreted as integer automatically:
```php
// ...
$cache[$choice] = true;
// when $choice = 0.5: $cache = [0 => true]
// when $choice = 1.0: $cache = [0 => true, 1 => true]
```
Then, when `$choice = 1.5` [this sentence][4] `isset($cache[1.5])` returns `true` because really checks `isset($cache[1])` and this key already exists, so `castableToString()` returns `false` (detected as duplicate) and the choices values are generated incrementing integers as values.
The PR's Effect
-------------
**Before:**
```html
<select id="form_foo" name="form[foo]">
<option value="0">Min</option>
<option value="1">Mid</option>
<option value="2">Max</option>
</select>
```
**After:**
```html
<select id="form_foo" name="form[foo]">
<option value="0.5">Min</option>
<option value="1">Mid</option>
<option value="1.5">Max</option>
</select>
```

Commit 0216e05605 removed the opening of connection to memcached server on call to `open()`, because it's assumed that connection is already opened. However, `close()` still closes the connection. As a result no more read/write calls can be made if session got closed, as the connection does not get reestablished.
Basically MemcacheSessionHandler should follow same logic as Memcache**d**SessionHandler, which is exactly what this MR acomplishes.

This fixes the infinite loop occurring when no input is provided for a question which has a validator and no max attempts (`null`), e.g. when using `SymfonyStyle::ask()` which automatically adds a validator.

According to https://tools.ietf.org/html/rfc3986#section-3.1:
<details>
<summary>`scheme = ALPHA *( ALPHA / DIGIT / "+" / "-" / "." )`</summary>
> Each URI begins with a scheme name that refers to a specification for
assigning identifiers within that scheme. As such, the URI syntax is
a federated and extensible naming system wherein each scheme's
specification may further restrict the syntax and semantics of
identifiers using that scheme.
> Scheme names consist of a sequence of characters beginning with a
letter and followed by any combination of letters, digits, plus
("+"), period ("."), or hyphen ("-"). Although schemes are case-
insensitive, the canonical form is lowercase and documents that
specify schemes must do so with lowercase letters. An implementation
should accept uppercase letters as equivalent to lowercase in scheme
names (e.g., allow "HTTP" as well as "http") for the sake of
robustness but should only produce lowercase scheme names for
consistency.
</details>
~~Fixing the regex to add missing chars could solve the issue. However according to the RFC, we should not allow underscores. But `\w+` permits it (removing it would be a minor BC break anyway).~~
~~IMHO, we should not care in this listener if the scheme is valid or not (a validator should be used instead), so I'd suggest to simply check if a scheme is provided or not.~~ I'm not using `parse_url($string, PHP_URL_SCHEME)` because `http:/symfony.com` or `http:symfony.com` is considered valid as containing a scheme.
Actually, I changed my mind about previous fix (28f816a) and went back to the regex, in order to have strings like `symfony.com?uri=http://example.com` properly transformed to `symfony.com?uri=http://example.com`

Fix edge case with StreamedResponse where headers are sent twice

If you have PHPs output buffering enabled (`output_buffering=4096` in your php.ini per example), there is an edge case with the StreamedResponse object where the headers are sent twice. Even if it is harmless most of the time, it can be critical sometimes (per example, if an `Access-Control-Allow-Origin` header is duplicated the browser will block the request).
Explanation: because the streamed response may need the request in order to generate the content, the `StreamedResponseListener` class calls the send method of the `Response` when the event `kernel.response` is fired. To prevent the content from being duplicated, a state has been introduced in the `sendContent()` method and it works fine.
But there is an edge case is the headers of the response. If the content generated by the `sendContent()` method is smaller than the value defined for `output_buffering` in the `php.ini` then the buffer won't be flushed and the `headers_sent()` function will return false.
Therefore when `$response->send()` is called for the second time (in the `app.php` file), the headers will be sent a second time.

Trim constant values in XmlFileLoader

When an XML config file gets long, it's nice to put the constant name into the next line like this:
```xml
<parameter key="som_very_very_long_constant_name" type="constant">
Some\Namespace\That\Is\Sufficiently\Long\To\Require\A\LineBreak::someLongishConstantName
</parameter>
```
If that’s the case, `constant()` will try and find a constant including the spaces. While it is theoretically possible to have a constant in PHP that starts or ends with a space, it’s impossible for class constants and only doable using `define(" FOO ", …);`. So that’s probably an edge case we can ignore.
