Subject: [PATCH] added better L2 handling for ptp, if it's down we don't try
 to call on that port in groupdial anymore, also we try to get it up then.
 Additionally added the configoptions  ntdebugflags and ntdebugfile to debug
 the mISDNuser NT Stack (should have done that ages before..). isdn_lib.c
 compiles again.
