Subject: [PATCH 1/2] mempool: make event callbacks process-private

Callbacks for mempool events were registered in a process-shared tailq.
This was inherently incorrect because the same function may be loaded to a
different address in each process.
Make the tailq process-private.
Use the EAL tailq lock to reduce the number of different locks this module
operates.
