Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * labels.Builder: allow re-use of result slice This reduces memory allocations where the caller has a suitable slice available. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * model/relabel: re-use source values slice To reduce memory allocations. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Unwind one change causing test failures Restore original behaviour in PopulateLabels, where we must not overwrite the input set. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * relabel: simplify values optimisation Use a stack-based array for up to 16 source labels, which will be the vast majority of cases.
