Merge branch '2.7' into 2.8

* 2.7:
  [DependencyInjection] fix dumped YAML snytax
  Remove InputOption::VALUE_REQUIRED mode from $default parameter description as InputOption::setDefault() throws an exception only when called in InputOption::VALUE_NONE mode. In practice the $default value could still be accessed in InputOption::VALUE_REQUIRED mode in case InputOption was never set but accessed from InputDefinition::getOption() method
  [Form] Fixed violation mapping if multiple forms are using the same (or part of the same) property path
  [TwigBridge] Symfony 3.1 forward compatibility
