This commits removes stuff from different upgradelib files, used exclusively by the already deleted upgrade steps. Given such exclusivity it was not needed to proceed with a 2-phase deprecation as far as the functions were 100% internal to upgrade. This is the list of deleted functions, all them docummented in their corresponding upgrade.txt files: - repository_picasa_admin_upgrade_notification(); - repository_googledocs_admin_upgrade_notification(); - repository_boxnet_admin_upgrade_notification(); - repository_alfresco_admin_security_key_notice(); - qtype_essay_convert_to_html(); - portfolio_picasa_admin_upgrade_notification(); - portfolio_googledocs_admin_upgrade_notification(); - portfolio_boxnet_admin_upgrade_notification(); - mod_book_migrate_moddata_dir_to_legacy(); - mod_book_migrate_all_areas(); - mod_book_migrate_area(); - mod_assignment_pending_upgrades_notification(); - upgrade_mysql_fix_unsigned_and_lob_columns(); - upgrade_course_completion_remove_duplicates(); - upgrade_save_orphaned_questions(); - upgrade_rename_old_backup_files_using_shortname(); - upgrade_mssql_nvarcharmax(); - upgrade_mssql_varbinarymax(); - upgrade_fix_missing_root_folders(); - upgrade_course_modules_sequences(); - upgrade_grade_item_fix_sortorder(); - upgrade_availability_item();
