This patch corrects the following: - Fix to libtli/libxti to correctly handle a continuation data message still on the stream head. - Fixes a streams problem in libxti. The t_getprotaddr() function will cause a memory core dump if either of its second or third argument is NULL. - Fixes a problem in which an application using the X/Open Transport Interface (XTI) and the DECnet/OSI transport provider is unable to disconnect a rejected request.
