be prevented.

cc516af4cc Instead of disallowing writes to fts5 tables if there are fts5vocab cursors open on them (commit [c49a6ed7]), abort any fts5vocab queries if the on-disk structure of the fts5 table changes.

84c501bac1 Initial code to make shadow tables read-only to ordinary SQL. The now 
xShadowName method is added to the sqlite3_module object and is used
to identify potential shadow tables.  The SQLITE_PREPARE_SHADOW argument
to sqlite3_prepare_v3() is defined.  It is designed to permit writing to
shadow tables, but is currently an unused placeholder.
