splitted stroke plugin to several files:

socket: reads messages from socket, dispatching
  config: process add/del conn, serves configs through backend_t
  control: controlling of the daemon (up/down/route/...(
  cred: credential loading, serves creds through credential_set_t
  ca: ca sections from ipsec.conf, serves cdp's through credential_set_t
  list: log status information to stroke console (status/statusall/list*)
  shared_key: shared key implementation for keys read from ipsec.secrets
  plugin: registers stroke plugin and starts socket w/ thread
