Commits-------6296a24 Standalone query string normalizationDiscussion----------[HttpFoundation] Standalone query string normalizationI wanted to leverage query string normalization in a test. I considered copying this code to my own library but I noticed that the only instance data `getQueryString` needed to know from the `Request` was `QUERY_STRING` so I broke the rest out into a standalone static function.---------------------------------------------------------------------------by simensen at 2012-07-02T20:05:59ZI made the requested changes.---------------------------------------------------------------------------by fabpot at 2012-07-02T20:10:27ZCan you squash your commits?

Dumping a `ReflectionAttribute` just yields `ReflectionAttribute {#4711}` which is not really helpful. This PR attempts to fix this.```ReflectionAttribute {#4711  name: "App\MyAttribute"  arguments: array:2 [    0 => "one"    "extra" => "hello"  ]}```While working on this, I noticed that class constants (which can be reflected on since PHP 7.1) are just dumped as plain values, so I've also added a caster for `ReflectionClasConstant` as bonus.The full output for the `LotsOfAttributes` fixture class that is included with is PR looks like this:<details>```^ ReflectionClass {#7  +name: "Symfony\Component\VarDumper\Tests\Fixtures\LotsOfAttributes"  modifiers: "final"  implements: []  constants: array:1 [    0 => ReflectionClassConstant {#20      +name: "SOME_CONSTANT"      +class: "Symfony\Component\VarDumper\Tests\Fixtures\LotsOfAttributes"      modifiers: "public"      value: "some value"      attributes: array:2 [        0 => ReflectionAttribute {#33          name: "Symfony\Component\VarDumper\Tests\Fixtures\RepeatableAttribute"          arguments: array:1 [            0 => "one"          ]        }        1 => ReflectionAttribute {#34          name: "Symfony\Component\VarDumper\Tests\Fixtures\RepeatableAttribute"          arguments: array:1 [            0 => "two"          ]        }      ]    }  ]  properties: array:1 [    "someProperty" => ReflectionProperty {#19      +name: "someProperty"      +class: "Symfony\Component\VarDumper\Tests\Fixtures\LotsOfAttributes"      modifiers: "private"      attributes: array:1 [        0 => ReflectionAttribute {#30          name: "Symfony\Component\VarDumper\Tests\Fixtures\MyAttribute"          arguments: array:2 [            0 => "one"            "extra" => "hello"          ]        }      ]    }  ]  methods: array:1 [    "someMethod" => ReflectionMethod {#21      +name: "someMethod"      +class: "Symfony\Component\VarDumper\Tests\Fixtures\LotsOfAttributes"      returnType: "void"      parameters: {        $someParameter: ReflectionParameter {#28          +name: "someParameter"          position: 0          attributes: array:1 [            0 => ReflectionAttribute {#42              name: "Symfony\Component\VarDumper\Tests\Fixtures\MyAttribute"              arguments: array:1 [                0 => "three"              ]            }          ]          typeHint: "string"        }      }      attributes: array:1 [        0 => ReflectionAttribute {#27          name: "Symfony\Component\VarDumper\Tests\Fixtures\MyAttribute"          arguments: array:1 [            0 => "two"          ]        }      ]      modifiers: "public"    }  ]  attributes: array:1 [    0 => ReflectionAttribute {#22      name: "Symfony\Component\VarDumper\Tests\Fixtures\MyAttribute"      arguments: []    }  ]  extra: {    file: "./src/Symfony/Component/VarDumper/Tests/Fixtures/LotsOfAttributes.php"    line: "15 to 28"    isUserDefined: true  }}```</details>Commits-------34dbf01 [VarDumper] Support for ReflectionAttribute.
