This patch adds a better dcerpc server infastructure.

1.) We now register endpoint servers add startup via register_backend()
    and later use the smb.conf 'dcerpc endpoint servers' parameter to setup the dcesrv_context

2.) each endpoint server can register at context creation time as much interfaces as it wants
    (multiple interfaces on one endpoint are supported!)
    (NOTE:  there's a difference between 'endpoint server' and 'endpoint'!
	    for details look at rpc_server/dcesrv_server.h)

3.) one endpoint can have a security descriptor registered to it self
    this will be checked in the future when a client wants to connect
    to an smb pipe endpoint.

4.) we now have a 'remote' endpoint server, which works like the ntvfs_cifs module
    it takes this options in the [globals] section:

    dcerpc remote:interfaces = srvsvc, winreg, w32time, epmapper
    dcerpc remote:binding = ...
    dcerpc remote:user = ...
    dcerpc remote:password = ...

5.) we currently have tree endpoint servers: epmapper, rpcecho and remote

    the default for the 'dcerpc endpiont servers = epmapper, rpcecho'

    for testing you can also do
    dcerpc endpoint servers = rpcecho, remote, epmapper
    dcerpc remote:interfaces = srvsvc, samr, netlogon

6,) please notice the the epmapper now only returns NO_ENTRIES
    (but I think we'll find a solution for this too:-)

7.) also there're some other stuff left, but step by step :-)

This patch also includes updates for the
register_subsystem() , ntvfs_init(), and some other funtions
to check for duplicate subsystem registration
