97601244e2 Enhance the vtablog extension so that it shows the value of 
sqlite3_vtab_distinct() in xBestIndex, and so that provides the new
consume_order_by option that can cause xBestIndex to set the
orderByConsumed flag.

1935887a68 Ensure that all fields of static sqlite3_module objects are explicitly 
initialized, in order to hush-up nuisance compiler warnings.

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.
