Log Message:
SQL connection objects now get their type converters from a distinct
property namespace for each DBAPI driver.  For example a driver using the
'cx_Oracle' module will get its type converters from the
'cx_Oracle.sql_types' property namespace, instead of 'peak.sql_types'.  For
backward compatibility, these driver-specific namespaces are set up to
fall back to 'peak.sql_types' for their defaults.  Type converter
construction has also been improved, to eliminate conversion overhead
completely when no conversions are required for a specific query.  Also,
SQL connections now offer a method that will create a row conversion
function for a given result description and optional postprocessing
function.  This new method should now be used in place of direct access to
the 'typeMap' attribute of connection objects.
