I've gone over a few of the mofified files (those
which were showing warnings and errors to CiBoT. Some of them
have been fixed completely, while others only have fixed
for the lines belonging to this issue (lib/tests/moodlelib_test.php)
for example.
The current ->setMethods() has been silently (won't emit any
warning) in PHPUnit 9. And will stop working (current plans)
in PHPUnit 10.
Basically the now deprecated method has been split into:
- onlyMethods(): To point to existing methods in the mocked artifact.
- addMethods(): To point to non existing (yet) methods in the mocked
artifact.
In practice that means that all our current setMethods() calls can be
converted to onlyMethods() (existing) and done. The addMethods() is
mostly useful on development phases, not final testing.
Finally note that <null> isn't accepted anymore as parameter to
double all the methods. Instead empty array [] must be used.

All the setup/teardown/pre/post/conditions template methods
now are required to return void. This was warned with phpunit 7
and now is enforced.
At the same time, fix a few wrong function names,
provider data and param types, return statements...
