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()

This files describes API changes in the editor_atto code.
=== 3.4 ===
* The following functions, previously used (exclusively) by upgrade steps are not available
anymore because of the upgrade cleanup performed for this version. See MDL-57432 for more info:
- atto_equation_update_librarygroup4_setting()
=== 3.0 ===
* Rangy updated to 1.3.0.
Rangy has deprecated the createCssClassApplier function in this version (it is now createClassApplier).
=== 2.9 ===
* When adding a shortcut to the button of a plugin, atto will add a layer of validation
to ensure that only the required keys are pressed. However, if you are using a custom
keyConfig object you must validate the shortcut yourself. This is particularly important
for non-English keyboard users. For more information read the documentation of
EditorPluginButtons::_addKeyboardListener() and MDL-47133.
