This PR ensures that PHP [values which would be interpreted as booleans][1] in older versions of the YAML spec are escaped with single quotes when dumped by the Dumper.
For example, dumping this:
```php
array(
'country_code' => 'no',
'speaks_norwegian' => 'y',
'heating' => 'on',
)
```
Will produce this YAML:
```yaml
country_code: 'no'
speaks_norwegian: 'y'
heating: 'on'
```

3760e67 [Yaml] Improve YAML boolean escaping
- Moves dumping single-quoting logic into Yaml\Escaper
- Ensures that PHP values which would be interpreted as booleans in
older versions of the YAML spec are escaped with single quotes when
dumped by the Dumper.
This removes the unused use statements which were not catched by
PHP-CS-Fixer because of string occurences. It also fixes some invalid
phpdoc (scalar is not recognized as a valid type for instance).
To let opcode caches optimize cached code, the `PHP_VERSION_ID`
constant is used to detect the current PHP version instead of calling
`version_compare()` with `PHP_VERSION`.

When a line contains only a dash it cannot safely be assumed that it contains a nested list or an embedded mapping. If the next line starts with a dash at the same indentation, the current line's item is to be treated as `null`.

fc85435 fix handling of empty sequence items
Asterisks in unquoted strings are used in YAML to reference
variables. Before Symfony 2.3.19, Symfony 2.4.9 and Symfony 2.5.4,
unquoted asterisks in inlined YAML code were treated as regular
strings. This was fixed for the inline parser in #11677. However, an
unquoted * character now led to an error message like this:
```
PHP Warning: array_key_exists(): The first argument should be either a string or an integer in vendor/symfony/symfony/src/Symfony/Component/Yaml/Inline.php on line 409
[Symfony\Component\Yaml\Exception\ParseException]
Reference "" does not exist at line 171 (near "- { foo: * }").
```
When a line contains only a dash it cannot safely be assumed that
it contains a nested list or an embedded mapping. If the next line
starts with a dash at the same indentation, the current line's item
is to be treated as `null`.

unified return null usages
| Q | A
| ------------- | ---

This PR unifies the way we return `null` from a function or method:
* always use `return;` instead of `return null;` (the current code base uses both);
* never use `return;` at the end of a function/method.
