Too many functions, too different parameters, unnecessary DB queries.
All repositories developed for Moodle 2.3-2.5 will continue to work.
Also get rid of DB field files_reference.lifetime, it is not used by
anybody except repository itself.
This parallels question_attempt->minfraction, which allows the
fractional mark to go below zere.
This is needed to allow the certainty-base marking behaviours to work
better.
Using 'should see' outputs rather than an incorrect
xpath query. Also our custom selectors are not properly
used by WebAssert so switching to find xpath.
