Module traits
capability traits shared across modules.
A trait that more than one module's roles are built from lives here, so each module includes it instead of declaring its own copy.
Resettable reset(): back to the initial state. An arena-style
allocator frees every block at once (alloc/allocator.h's
ArenaAllocator); a filter clears its history, so the next
output is the response from silence (dsp/sample_filter.h's
SampleFilter).
