Deprecate the SQLITE_ALLOW_COVERING_INDEX_SCAN compile-time option when it is
turned off. This probably will impact no-one. If it does, they will get an
error message instructing them to contact developers, so that we can get
feedback that somebody is actually using this feature. Start-time disabling
of covering index scan is not affected.
