r1486: commit the start of the generic server infastructure

the idea is to have services as modules (smb, dcerpc, swat, ...)

the process_model don't know about the service it self anymore.

TODO:
- the smbsrv should use the smbsrv_send function
- the service subsystem init should be done like for other modules
- we need to have a generic socket subsystem, which handle stream, datagram,
  and virtuell other sockets( e.g. for the ntvfs_ipc module to connect to the dcerpc server
  , or for smb or dcerpc or whatever to connect to a server wide auth service)
- and other fixes...

NOTE: process model pthread seems to be broken( but also before this patch!)
