MDL-41284 stop using log table for login weekly and monthly stats

We already have stats for each day, the SUM is what we want there...
MDL-41284 hack stats to use new log readers if available
MDL-44106 add WS_SERVER constant to all web service calls

This will help us hack around some nasty webservice problems,
such as require_login() and it will be used to set proper 'ws' origin
in logged events.
MDL-44106 add origin info to $PAGE object and use it in logs
MDL-44107 deprecated event_base::can_view()

The problem is that it would be too expensive and difficult
to implement reliable access control in each event.
