irmd: Allow direct rbuff between local processes
This allows bypassing the IPCP for local processes that share the same
packet pool, lowering latency between processes to comparable levels
as Unix sockets (RTT in the order of a microsecond).
For local processes, no IPCPs are needed:
$ irm b prog oping n oping
$ oping -l
Ouroboros ping server started.
New flow 64.
Received 64 bytes on fd 64.
The direct IPC can be disabled with the DISABLE_DIRECT_IPC build
flag. Note that this is needed for rumba 'local' experiments to
emulate network topologies. Without this flag all processes will just
communicate directly.
