MDL-45991 groups: Auto-create groups with ungrouped users only
When using auto-create groups, sometimes it is needed to only create
groups with users that are not already inside a course group. This
patch creates a checkbox that will ignore users that are in already
existing groups. It alters the groups_get_potential_members function so
that the eligible users are retrieved entirely though sql.
This combines the following changes:
* Event for group member added
* Event for group member removed
* Event for group created
* Event for grouping created
* Event for group updated
* Event for grouping updated
* Event for group deleted
* Event for grouping deleted
* Adding tests for deleting functions
* Bulk remove of members uses low-level API
The reason for this is that a bulk event has no value from a logging
perspective as it is not granular. So now, the API is a bit slower,
but the information the events contain makes sense, beside this is
not (and should not be) used very often.
The reason why the events_trigger_legacy() is kept is because we
cannot create a new event for this, as we don't encourage developers
to created bulk events, for the reasons mentioned above.
I removed the call that gets the user record from the function
groups_remove_member() as it was not required and only appeared
to check if the user existed. It appears to be safe not to do
this check as nothing would fail down the line.
* Bulk unassign of groupings uses low-level API
As the previous commit, we keep the legacy event for now as it would
be wrong to create a new event to replace it.
Also, the code has been changed to call the low-level API to unassign
groups from groupins, even though at the moment there are no
events for that function.
* Bulk deletion of groups uses low-level API
Again, we keep the legacy event because replacing it would force
us to create a new event that does not make sense. See MDL-41312.
* Bulk deleting of groupings uses low-level API
* Asserting legacy event name in unit tests
* Minor SQL query and code improvements

This change adds conditional availability support for sections analagous to
that already available for activities. (Backend, UI, backup/restore.)
In order that this feature does not reduce performance, section cacheing has
also been added using a new course 'sectioncache' field analagous to modinfo.
The new feature integrates with activity availability so that activities
inside sections which are not available are automatically not available
themselves (meaning it works to restrict access).
From now on, all English strings use the new syntax. They are not
eval()'ed any more and the only valid placeholders are {$a} and
{$a->foobar}. No extra quotes escaping, dollar sign escaping and putting
double percent signs.
The modified files were exported from AMOS database repository in the
new syntax and were re-ordered by stringid. Standard GNU/GPL and PHPdoc
blocks are added. Where there was no copyright note so far, I added the
default one with Martin Dougiamas as the copyright holder.
Live long and prosper.
