eab0e10304 In extensions rtree, fts3 and fts5, ensure that when dynamic buffers are bound 
to persistent SQL statements using SQLITE_STATIC, the binding is replaced with
an SQL NULL before the buffer is freed. Otherwise, a user may obtain a pointer
to the persistent statement using sqlite3_next_stmt() and attempt to access
the freed buffer using sqlite3_expanded_sql() or similar.
