Many SCR's in WFM
-----------------

Create a new scr instance:

  integer handle = SCROpen (string name, bool check_version);

  The name must be a valid y2component name (e.g. "scr", "chroot=/mnt:scr").
  On error a negative value is returned.


Close a scr instance:

  void SCRClose (integer handle);


Get the name of a scr instance:

  string name = SCRGetName (integer handle);


Set/get the default instance:

  void SCRSetDefault (integer handle);
  integer handle = SCRGetDefault ();


The use of an instace has not changed:

  whatsoever result = SCR::Read (...);	// use default handle


At startup the default handle is 0 with the name is "scr".
