/**
* Main upgrade tasks to be executed on Moodle version bump
*
* This function is automatically executed after one bump in the Moodle core
* version is detected. It's in charge of performing the required tasks
* to raise core from the previous version to the next one.
*
* It's a collection of ordered blocks of code, named "upgrade steps",
* each one performing one isolated (from the rest of steps) task. Usually
* tasks involve creating new DB objects or performing manipulation of the
* information for cleanup/fixup purposes.
*
* Each upgrade step has a fixed structure, that can be summarised as follows:
*
* if ($oldversion < XXXXXXXXXX.XX) {
* // Explanation of the update step, linking to issue in the Tracker if necessary
* upgrade_set_timeout(XX); // Optional for big tasks
* // Code to execute goes here, usually the XMLDB Editor will
* // help you here. See {@link http://docs.moodle.org/dev/XMLDB_editor}.
* upgrade_main_savepoint(true, XXXXXXXXXX.XX);
* }
*
* All plugins within Moodle (modules, blocks, reports...) support the existence of
* their own upgrade.php file, using the "Frankenstyle" component name as
* defined at {@link http://docs.moodle.org/dev/Frankenstyle}, for example:
* - {@link xmldb_page_upgrade($oldversion)}. (modules don't require the plugintype ("mod_") to be used.
* - {@link xmldb_auth_manual_upgrade($oldversion)}.
* - {@link xmldb_workshopform_accumulative_upgrade($oldversion)}.
* - ....
*
* In order to keep the contents of this file reduced, it's allowed to create some helper
* functions to be used here in the {@link upgradelib.php} file at the same directory. Note
* that such a file must be manually included from upgrade.php, and there are some restrictions
* about what can be used within it.
*
* For more information, take a look to the documentation available:
* - Data definition API: {@link http://docs.moodle.org/dev/Data_definition_API}
* - Upgrade API: {@link http://docs.moodle.org/dev/Upgrade_API}
*
* @param int $oldversion
* @return bool always true
