MDL-38456 Allow colons in paths passed to mdeploy.php utility

in C:\apache.
MDL-38215 Fix cross-db support in workshop SQL queries

The $sql used in these methods may contain multiple parts glued
together by the UNION operator. Simply appending the ORDER BY statement
to the end of the query does not work in all DBs (failure reported at
Oracle). Following the pattern already applied in MDL-30051, we wrap the
SQL into yet another SELECT statement and perform ordering there.

Credit goes to Sara Cenni for suggesting the fix.

MDL-38490 question preview, variant is attempt (not display) option
MDL-38397 question editing: only validate default mark if present.

Most qtypes have that field, but not all. multianswer is an example in core.
Also some contrib qtypes.
MDL-38355 qtype_multianswer: input boxes too big in Russian.

... and any other language where the characters take multiple
bytes in UTF-8.

This fix was worked out by Dušan Ristić. I am just committing it.
MDL-38388 qformat_blackboard_six: fix question image import

This works on the expectation that the returned array from readdata()
is opaque and will be fed directly into readquestions() since
filebase is different per file and needs to be set up appropriately
before each parse.
MDL-38395 question categories: wrong URLs after editing.

The problem was that array1 + array2 takes the values from
array1 when a key appears in both places.

While working on this area, I updated it to use html_writer.
MDL-38363 qtype_calculated. Fix warnings.
MDL-38412 fix quiz reports group mode weirdness.

Moodle currently selected group uses the session. This can cause weird
effects when you have two tabs open. This is particularly weird in the
quiz reports, where some actions like delete attempt are checked against
the currently selected group.

The solution is to put the currently selected group into the URL for all
actions like delete/regrade attempt, regrade all attempts, download and
sort table.
