=item * &excess_filesize_warning()

Returns warning message if upload of file to authoring space, or copying
of existing file within authoring space will cause quota for the authoring
space to be exceeded.

Same, if upload of a file directly to a course/community via Course Editor
will cause quota for uploaded content for the course to be exceeded.

Inputs: 7
1. username or coursenum
2. domain
3. context ('author' or 'course')
4. filename of file for which action is being requested
5. filesize (kB) of file
6. action being taken: copy or upload.
7. quotatype (in course context -- official, unofficial, community or textbook).

Returns: 1 scalar: HTML to display containing warning if quota would be exceeded,
otherwise return null.

=item * clean_path($name)

Performs clean-up of directories, subdirectories and filename in an
embedded object, referenced in an HTML file which is being uploaded
to a course or portfolio, where
"Upload embedded images/multimedia files if HTML file" checkbox was
checked.

Clean-up is similar to replacements in lonnet::clean_filename()
except each / between sub-directory and next level is preserved.
