Timothy Flynn f8f36effc9 LibSQL: Limit the allowed depth of an expression tree ...

According to the definition at https://sqlite.org/lang_expr.html, SQL
expressions could be infinitely deep. For practicality, SQLite enforces
a maxiumum expression tree depth of 1000. Apply the same limit in
LibSQL to avoid stack overflow in the expression parser.
