* hurd/hurdlookup.c (__file_name_lookup_under): New function. (__hurd_file_name_lookup, __hurd_file_name_lookup_retry, __hurd_file_name_split): Rewritten to take callback functions for using any needed init or dtable port, instead of passing in crdir and cwdir ports. (__file_name_lookup, __file_name_split): Use new calling convention; pass _hurd_ports_use and __getdport as the callback functions. * sysdeps/mach/hurd/chroot.c: Use __file_name_lookup_under instead of __hurd_file_name_lookup. * sysdeps/mach/hurd/chdir.c: Likewise. * sysdeps/mach/hurd/fchdir.c: Likewise. * hurd/fchroot.c: Likewise.
