function imageapi_optimize_pipeline_name_validate in Image Optimize (or ImageAPI Optimize) 7.2

Element validate function to ensure unique, URL safe pipeline names.

This function is no longer used in Drupal core since image pipeline names are now validated using #machine_name functionality. It is kept for backwards compatibility (since non-core modules may be using it) and will be removed in Drupal 8.
