1ea0443c2d Add new sqlite3_prepare_v3() flag SQLITE_PREPARE_NO_VTAB, for preparing 
statements that are not allowed to use any virtual tables. Use this to prevent
circular references in triggers on virtual table shadow tables from causing
resource leaks.

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.

be0bc8bb4d Have fts5 close any open blob-handle when a new savepoint is opened. This 
ensures that fts5 does not prevent DROP TABLE statements (which always open a
savepoint) from succeeding.
