Remove datatypes.set_here()

This used to store the directory of the main config file and was
used to expand %(here)s.  Now, %(here)s has changed to mean the
directory of the file containing it, so it will be different for
files included via an [include] section.  Other code now sets
'here' and tests for all documented places %(here)s can be used
were added in 0eb3b885de30adbf2c4cb9bc46f399764e296ed0.
