Merge branch '6.3' into 6.4

* 6.3:
  [5.4] Allow PhpUnitBridge v7
  [Console] block input stream if needed When the input stream used in the question helper is not blocking, the default value is always used as the stream return false. In order to fix that, we force the stream to be in blocking state and go back to the old state after so other logic is not impacted by this change
