ipcpd: initial IPC processes

Basic functions for implementation of IPC processes, and
implementation of core functions of the shim IPCP over UDP.  Updates
to the build system to compile these IPC processes, as well as some
fixes in the irmd (rudimentary capturing exit signals) and some fixes
in the library, mainly relating to the messaging.

Basic implementation of creation / bootstrapping / deletion of the
shim UDP. Placeholders for other functions.
