Add the SQLITE_VTAB_USES_ALL_SCHEMAS option to sqlite3_vtab_config(). Update

Browse Source 
the sqlite_dbpage, sqlite_dbdata, and sqlite_dbptr virtual tables to make
use of that interface.  This was formerly handled by the internal
sqlite3VtabUsesAllSchemas() routine that was called directly from sqlite_dbpage.
But since sqlite_dbdata and sqlite_dbptr are an extension, an external
interface to that functionality had to be provided.
