Russell Smith 1fcf0ca8a5 MDL-35628 performance: Remove dirname() where possible. 
dirname() is a slow function compared with __DIR__ and using
'/../'.  Moodle has a large number of legacy files that are included
each time a page loads and is not able to use an autoloader as it is
functional code.  This allows those required includes to perform as
best as possible in this situation.
