The test now also creates TIME type values and checks that they are
converted correctly. Also added NULL value tests for all values and made
required adjustments to the code.
The type and name parsing functions could move outside of allocated memory
as they didn't check for the terminating null character. Also fixed the
printf format string used when the list of used tables is being created.
Fixed CDC testing connector to abort on error and added some extra output
to the cdc_datatypes test.
