fix handling of empty sequence items

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`.

improve error when detecting unquoted asterisks

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: * }").
```
properly mask escape sequences in quoted strings
