ipcpd: Refactor ipcpi struct
The ipcp-ops header was removed and merged into ipcp.h. The common components dif_name and ipcp_type have been moved to the main ipcp struct. After this move, ipcp_data only contained shim information, so it was renamed to shim_data. The ipcp_init() function checks the type and will only include the shim_data if the type is not an IPCP_NORMAL. All ipcps have been adapted to this change in API.
