lib, irmd, ipcpd: Change of IRM API

This changes the IRM API after discussions with Dimitri. The register
operation is now split into a bind and register operation. The same
for unregister; unbind and unregister. PIDs are now used as the
application instance name. A name for a PID is only provided for
scriptability in bash. It is therefore also no longer passed down to
the IPCP. Every operation on an IPCP through the IRM API has to use
the PID. Quering of the PIDs by name is possible. The IRM tool has
been updated to use this new API as well. A subcommand 'ipcp' has been
added for operations that take effect on IPCPs only.

Fixes #12
