ipcpd: normal: Add initial steps for N+1 flow allocation

This adds the initial framework for flow allocation between two N+1
endpoints. The FMGR will receive flow allocation requests and will
create a connection as a result, addressed to the right address, it
will also pass a flow allocation message to this address. Upon receipt
on the other side, the FMGR will be receive a flow allocation message
and a pointer to a new connection. The FMGR can then accept or destroy
the connection. This commit also introduces the RMT function, which is
needed by the FRCT to forward its SDUs on the right file descriptor.
