Enable the header metadata so that we have timestamps again. Rework allocation in the link a little. Reuse previously allocated buffers when possible. Keep track of where the buffers was allocated. Make some more convenience functions to initialize buffer headers. Make it so that we move allocations to the app. Make some helpers to make memfd memory in pinos now that we will be able to do all allocation there.
