            71455: MNT-10067 : Cleanup alf_prop_XXX data
            Fixed queries, separated the creation of tables.
            71491: MNT-10067 : Cleanup alf_prop_XXX data
            Changes to MySQl script:
             - Added index to the id column in temp tables.
             - Removed transaction marks.
             - Changed the format of temp tables to MyISAM.
            71756: MNT-10067 : Cleanup alf_prop_XXX data
            Implemented the changes to the scripts for all DBs.

-- The script intended to clean obsolete properties from alf_prop_xxx tables
-- see MNT-10067
--
-- All the useful properties in alf_prop_root are gathered in temp_prop_root_ref.
-- These can be found in alf_audit_app.disabled_paths_id, alf_audit_entry.audit_values_id, alf_prop_unique_ctx.prop1_id
-- Then the obsolete ones are put to temp_prop_root_obs and deleted.
--
-- Afterwards, all the usefull properties in alf_prop_value are gathered in temp_prop_val_ref.
-- These can be found in alf_audit_app.app_name_id, alf_audit_entry.audit_user_id, alf_prop_link.key_prop_id, alf_prop_link.key_prop_id,
-- alf_prop_unique_ctx.value1_prop_id, alf_prop_unique_ctx.value2_prop_id, alf_prop_unique_ctx.value3_prop_id.
-- All of these tables are participating in recording audit. Afterwards the obsolete values in alf_prop_value are deleted.
-- Knowing all the ID's gathered in temp_prop_val_obs.long_value with a combination of the properties type in temp_prop_val_obs.persisted_type,
-- the rest of the values used in audit can be deleted from alf_prop_string_value, alf_prop_serializable_value, alf_prop_double_value.
