Immutable appends the option to mark the db immutable on connections

func LogSqliteDeprecation 

func LogSqliteDeprecation()

func Open

If the heads of all channels are being deprecated (including the default channel), the package is removed entirely from the index. MaybeRemovePackages deletes all bundles from the associated package from the bundles array, so that the subsequent Deprecate() call can proceed with deprecating other potential bundles from other packages.
