* Improved robustness while parsing the tokenize= arguments in
FTS5.
* Enhancements to covering index prediction in the query planner.
* Do not let the number of terms on a VALUES clause be limited by
SQLITE_LIMIT_COMPOUND_SELECT, even if the VALUES clause
contains elements that appear to be variables due to
double-quoted string literals.
* Fix the window function version of group_concat() so that it
returns an empty string if it has one or more empty string
inputs.
* In FTS5 secure-delete mode, fix false-positive integrity-check
reports about corrupt indexes.
* Syntax errors in ALTER TABLE should always return SQLITE_ERROR.
In some cases, they were formerly returning SQLITE_INTERNAL.
* Other minor fixes.
