WG: again compilation of lcr

pull lcr again. the mISDNuser header paths have changed. i changed more stuff. also try to remove the /usr/include/mISDNuser directory. it is obsolete. now compat_af_isdn.h can be removed from openbsc also. todo so, replace the include of this file by: #include <mISDN/mISDNcompat.h> int __af_isdn = MISDN_AF_ISDN; maybe it is better to use "static int", so it will not conflict when linking to lcr... we will see. the function call init_af_isdn(); can be removed.
