Log Message:
Got rid of weird data structure manipulations that were needed for
parameter support, by converting to stream-oriented SQL generation.  See
'ISQLWriter' and 'ISQLRenderable' for details.  Also, got rid of direct
calls to the 'sql*' methods and isolated them in 'SQLWriter', so that we
can create protocols for different backends that may need to generate
some SQL differently.
