There was a fatal error when calendar event linked to non-extant activities.
Now, instead of throwing an exception when a course_module does not exist, is_user_visible() will print a debug statement.
If a cm isn't in modinfo's cm list, then the user shouldn't be able to see that cm.
This fixes an issue where hidden activities would cause users to be unable to use moodle.
If there is invalid data in the availability condition (note: this
should not happen, but can do in unusual situations, such as
specifying a date after 2038 in 32-bit PHP), this should not
leave the course so broken that users cannot edit the activity and
update it.
Includes all the conditions that were in previous Moodle versions:
* Date
* Grade
* Completion (of another activity)
* User profile field
Also includes conditions that are used to reimplement
groupmembersonly:
* Grouping
* Group
For each condition, the component plus unit tests are included.
PLEASE NOTE: The code to actually check each condition is reused
from previous Moodle versions and has not been modified except to
pass codechecker. This is intentional, to reduce the risk of the
change and maximise the chance that behaviour is preserved. Some
of this code might not be very good and might need updating but
that can happen separately.

This commit defines the new /availability root folder, with
/availability/classes, /availability/tests, and
/availability/condition where the condition plugins will live.
Condition plugin prefix is availability_, e.g. availability_date.
Rationale for this organisation:
1. I was originally going to put this in /lib/availability but
it has been pointed out that putting even more junk in lib
is probably bad.
2. 'availability' and 'condition' are the two names used in code
to refer to this system ($CFG->enableavailability).
3. The prefix has to be short enough to allow database tables
(although in practice I assume that condition plugins will not
normally contain database tables).
The new API includes a Boolean tree structure that controls the
availability of an item.
