Description: 

Use entity_load_multiple('taxonomy_vocabulary') instead of taxonomy_get_vocabularies()
Drupal 7:

$vocabularies = taxonomy_get_vocabularies();

Drupal 8:

use Drupal\taxonomy\Entity\Vocabulary;
$vocabularies = Vocabulary::loadMultiple();

This became possible because calling entity_load_multiple($entity_type) without any arguments (or NULL) now loads all $entity_type type entities. Previously, you needed to call entity_load($entity_type, FALSE).
