lib, irmd, tools, ipcpd: updates to dev API.

The registration function has been moved to the irm tool, applications
now need to be registered by an administrator. Currently only supports
one instance per registered name, and an AP can be registered under
only one name.

The irmd can now start a registered server application on demand.

For the full functionality of the tool, execute "irm register".

AP name removed from flow allocation. Flow allocation does not send
the source ap name as it is quite useless. The accept() call now only
returns the AE name.
