9c94fcbea8 In the experimental and unsupported amatch.c extension, raise an error 
if a cost value is out of range even if the rule that the cost applies
to will never be used.

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.
