- replaced all usage of 'callback_xxx' functions with format_base methods
- made arguments of get_section_name(), get_course_url() more flexible
- deprecated function get_generic_section_name(), it's contents is moved to format_base

This commit coverts everything in the codebase to use the new
users_order_by_sql function when sorting lists of users. More details in
the bug.
Note that this does not change places where users are displayed in a
sortable table, and the sort order comes from the table.
The purpose of this method is to ensure that when we display lists of
users in different places, the default sort order is consistent.
Having this code centralised in one place them makes it possible to
improve things accross the board, and there is an example of that here.
There is logic so that if we are searching for particular string, then
users with an exact match are sorted first.
Tell the YUI drag/drop delegate that the show/hide and dock icons are not valid drag handles. Otherwise, a drag can be initiated by showing or hiding a block (probably not from docking one, but better safe than sorry). Not strictly related to MDL-34328, but likely to be encountered whilst testing - and closely related to another patch for MDL-34328.
Note that the "invalid" config option for the delegate takes a string - not an array - but can have multiple selectors separated by commas.
