   * Blocks are plugins; however, plugin information is not consistently
   * available from the various modules that render block forms (both core
   * and contrib). Resultantly, it is necessary to perform a variety of checks
   * to determine the plugin of a given block.
   *
   * Block forms for all plugins, excluding block_content and inline_block, can
   * be altered with hook_block_plugin_form_alter().
   *
   * Block forms for the block_content and inline_block plugins can be altered
   * with hook_block_type_form_alter().
