Subject: stats: create an enable phase, and a prepare phase. Enable more or
 less takes the place of check, but also allows stats to do some other
 configuration.  Prepare moves all of the code that readies a stat for dumping
 into a separate function in preparation for supporting serialization of
 certain pieces of statistics data. While we're at it, clean up the visitor
 code and some of the python code.
