Eloy Lafuente (stronk7) f83d212bcf MDL-57432 upgrade: remove unused functions/settings from upgradelib
All these functions were used only by deleted upgrade steps
so it's safe to proceed with straight deletion, considering
them internal. Deletion has been documented in corresponding
upgrade.txt files:

- upgrade_mimetypes()
- upgrade_fix_missing_root_folders_draft()
- upgrade_minmaxgrade() and upgrade_minmaxgradestepignored setting
- upgrade_course_tags()
- atto_equation_update_librarygroup4_setting()
- mod_lti_upgrade_custom_separator()

These have been kept because continue being used by restore:

- upgrade_group_members_only()
- upgrade_extra_credit_weightoverride()
- upgrade_calculated_grade_items()

ACTIVITY MODULES
----------------

These are main modules in Moodle, allowing various activities.


Each of these modules contains a number of expected components:

  mod_form.php: a form to setup/update a module instance

  version.php: defines some meta-info and provides upgrading code

  pix/icon.gif: a 16x16 icon for the module

  db/install.xml: an SQL dump of all the required db tables and data

  index.php: a page to list all instances in a course

  view.php: a page to view a particular instance

  lib.php: any/all functions defined by the module should be in here.
         constants should be defined using MODULENAME_xxxxxx
         functions should be defined using modulename_xxxxxx

         There are a number of standard functions:

         modulename_add_instance()
         modulename_update_instance()
         modulename_delete_instance()

         modulename_user_complete()
         modulename_user_outline()

         modulename_cron()

         modulename_print_recent_activity()
