Eloy Lafuente (stronk7) fbb0767536 MDL-69475 versions: bump all versions and requires in master
version = 2021052500 release version
requires= 2021052500 same than version

Why 20210525? (25th May 2021) ?

Because master is going to be Moodle 4.0, to be released
on November 2021. And, until then, we are going to have
a couple of "intermediate" releases:

- Moodle 3.10 to be released 9th November 2020. (2020110900)

  This version will be using versions from today to 2020110900
  (once it's released the YYYYMMDD part stops advancing).

- Moodle 3.11 to be released 10th May 2021. (2021051000)

  This version will be using versions from 3.10 release to 2021051000
  (once it's released the YYYYMMDD part stops advancing).

That means that all versions from today to 2021051000 are going
to be used by those 2 "intermediate" releases (3.10 and 3.11).

And we cannot use them in master, because it's forbidden to have
any overlapping of versions between branches (or different upgrade
paths will fail).

So, get that 2021051000, let's add it a couple of weeks to cover
the on-sync period (or a 2 weeks delay max!) and, the first version
that master can "own" in exclusive (without any overlap) is, exactly,
25th May 2021, hence our 20210525.

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()
