ipcpd: Add threadpool manager to DHT

This adds a threadpool manager to the DHT. This was needed because the
detached thread could cause a data race on shutdown.

The threadpool manager is revised to allow multiple instances in a
single program.

The irmd and ipcp now store commands in a buffer (list) instead of a
single buffer before passing it to handler threads.
