LTS (3.5) requires previous LTS (3.1)
This just deletes all the upgrade steps previous to 3.1.0. Some
small adjustments, like adding missing MOODLE_INTERNAL or tweaking
globals can also be applied when needed.
Also includes an upgrade step to prevent upgrading from any
version < 2016052300 (v3.1.0) as anti-cheating measure.
Next commit will get rid of/deprecate all the upgradelib functions
not used anymore in codebase.

If you dragged a question to the top of the quiz, it could
disappear. Several other cases of dragging questions to the
same place in sequence, but to a different page/section were
also failing, and have been fixed.

The sections are created on the edit quiz page, and then appear in the
navigation panel when the quiz is being attempted to help students find
their way around.
The 'Shuffle questions' setting has been moved from being per-quiz
to being a per-section.
This commit is actually the joint work of Mahmoud Kassaei and Tim Hunt
from The Open University. We could only use one persons name for the
commit and this time Mahmoud gets the credit/blame.
This feature is designed for use on pracice or formative quizzes.
It is available for quizzes that use Interactive or Immediate feedback
behaviour.
If the teacher turns this on in the quiz settings, then once a student
has finished a question, they get a 'Redo question' button beside the
question. If they click it, then the question they finished is replaced
by a new one so they can try again to practise that particul skill or
bit of knowledge a bit more.
When randomisation is involved, the studnets will be given a question or
variant that they have not seen before if possible.
Further improvements to this code, including resolving edge cases:
* The new feature can only be used when it is possible for the
previous question in the quiz to be complete.
* Also, this new feature cannot be used in combination with shuffle
questions, because that make no sense; nor in combination with
sequential navigation, because to make that work properly would be a lot
of effort. If someone needs that to work later, it should be possible
for them to implement it.
* There were changes in the edit renderer API, to try to make things
more consistent, and to make it less likely we will need to change
things again in the future. See mod/quiz/upgrade.txt.
* As part of this change, the styling of the Edit quiz page was tweaked
to make slighly more efficient use of the horizontal space, and to be
more symmetrical.
This patch adds completion options to Quiz similar to what is available in scorm.
One can have the quiz marked complete when either a passing grade is achieved or
all attempts are used up. This will allow a quiz to complete when the user "passes
or fails". (Where "fail" means "using up all attempts without passing".)
The sequence of questions that made up a quiz used to be stored as a
comma-separated list in quiz.questions. Now the same information is
stored in the rows in the quiz_slots table. This is not just 'better' in
a database design sense, but it allows for the future changes we will
need as we enhance the quiz in the MDL-40987 epic.
Having changed the database structure, all the rest of the code needs to
be changed to account for it, and that is done here.
Note that there are not many unit tests for the changed bit. That is
because as part of MDL-40987 we will be changing the code further, and
we will add unit tests then.
This data should all have been upgraded when moving to Moodle 2.1. It
was only kept as a back-up, and now, after 3 years have past, we can
clean it up.
Some columns needed to be renamed:
* quiz -> quizid
* question -> questionid
* grade -> maxmark
Then all the places that refer to those needed to be fixed.
Melinda Kraft reported having rows in their quiz_question_instances
table which caused various problems. These rows are meaningless, so I
have done a DB upgrade step to clean them up, which should deal with the
bad side-effets they were causing.
... before trying to create the unique index that should be there.
The violations may come from old buggy code.
We do two things.
1. First we delete all previews.
2. Then, if there are still problems, we renumber attempts to eliminate
the duplicates.
