- Disk quotas for content uploaded directly to a course (userfiles/docs/ and
userfiles/supplemental).
- Default is 500 MB, unless set at domain level, or individual course level.
- Domain defaults set by DC for: official courses, unofficial courses and
communities set via "Course/Community defaults" in "Set domain configuration".
- Quota for individual courses/communities set by DC via:
"View or modify a course or community"
- &excess_filesize_authorspace() renamed as excess_filesize_warning() to
support quota checking in course context, as well as in author context.
