RowData to Predicate adapter

[dmfs]

For testing purposes it can be useful to have a Predicate which takes RowData and matches all rows which contain the given RowData.

Usage:

new QueryRowSet(dataTable, new RowDataPredicate(rowData));

This would return all rows which contain the given rowData.

The question is, is that even possible at all? RowData is added to a ContentProviderOperation.Builder and requires a TransactionContext to do so. We could certainly subclass the Builder so it builds the actual predicate instead and provide an EmptyTransactionContext but that means you can not select by ids of virtual rows (because you need the TransactionContext). In most cases that's not an issue but in some edge cases it is.
