Eloy Lafuente (stronk7) 58b56e2395 MDL-71747 upgrade: remove all the < 3.9.0 upgrade steps
This just deletes all the upgrade steps previous to 3.9.0. Some
small adjustments, like tweaking globals can also be applied
when needed.

Also includes an upgrade step to prevent upgrading from any
version < 2020061500 (v3.9.0) as anti-cheating measure.

The next commits will proceed to deprecate / remove functions
that were exclusively (usually belonging to upgradelib) being
used by those, now removed, upgrade steps. This is the list
of code to remove and document in upgrade.txt files:

  - upgrade_analytics_fix_contextids_defaults()
  - upgrade_convert_hub_config_site_param_names()
  - upgrade_rename_prediction_actions_useful_incorrectly_flagged()
  - \mod_forum\task\refresh_forum_post_counts adhoc task.

And these is the code that has NOT been removed
because it may be needed later (no matter there aren't uses now):

  - \core_search\manager::clean_up_non_existing_area(), used by
  - \core\task\clean_up_deleted_search_area_task adhoc task

Official Chat Module for Moodle
------------------------------

The chat module now supports a backend daemon for
more efficiency.

It's still buggy and being worked on, but if you
want to test it and help out here are some quick
instructions:

1) Admin -> Config -> Modules -> Chat -> Settings

2) Set the method to "sockets" and set up the ports etc

3) Start the server like this (from the Unix command line):

   cd moodle/mod/chat
   php chatd.php --start &

4) Go to a chat room in Moodle and open it as normal.

KNOWN PROBLEMS

 - User list is not always working
 - Some browsers (eg Safari) cause lines to be repeated
   by 10 - 20 times
 - Occasionally "Document was empty" messages

Help solving these very welcome!
