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.

2964225247 Prevent the printf formatter from doing large memory allocations - larger 
than either the size of the static buffer for interfaces like
sqlite3_snprintf(), or larger than SQLITE_LIMIT_LENGTH for interfaces that
are associated with a database connection.  This helps to prevent DOS
attacks on products that let hostile sources inject arbitrary SQL.  It also
helps fuzzers run faster and more effectively.
