Move drupal_var_export() to \Drupal\Component\Utility

It can live in devel module, if somewhere

hmm...those scripts are not even working

If i run them inside the core directory..am i missing something or we should open a critical?

// var_export
db_create_table('wysiwyg_user', array (
  'fields' => 
  array (
    'uid' => 
    array (
      'type' => 'int',
      'unsigned' => true,
      'not null' => true,
      'default' => 0,
    ),
    'format' => 
    array (
      'type' => 'varchar',
      'length' => 255,
      'not null' => false,
    ),
   //......
  'module' => 'wysiwyg',
  'name' => 'wysiwyg_user',
));

// drupal_var_export
db_create_table('wysiwyg_user', array(
  'fields' => array(
    'uid' => array(
      'type' => 'int',
      'unsigned' => TRUE,
      'not null' => TRUE,
      'default' => 0,
    ),
    'format' => array(
      'type' => 'varchar',
      'length' => 255,
      'not null' => FALSE,
    ),
    //...
  'module' => 'wysiwyg',
  'name' => 'wysiwyg_user',
));

Both readable, just with drupal_var_export array( is not in new line..
i guess we can let this file be, if we want our dumps to obey our coding standards

i was thinking that maybe Drupal\Core would be more suitable, but other projects could use the same coding standards as Drupal, so why dont make sharing easier?:)
