f06db3e892 Fixes to the version of "varsep" group_concat so that (1) it builds under 
separate compilation and (2) omits tabs in source code and (3) runs faster
than trunk.  This variant of the group_concat_varsep branch might be preferred
over the tip because it preserves (undocumented) legacy behavior about the
position of separators relative to terms.

44183f83d0 What would it be like if you could add the keyword "STRICT" after a CREATE 
TABLE statement to cause the table to (1) allow only a few well-defined
datatypes, (2) rigidly enforce those types, (3) require NOT NULL on PK
columns, (4) always enforce foreign key constraint, and so forth?  This
branch seeks to explore that question.
