Unify the short-circuit translator logic
* libdiskfs/dir-lookup.c (short_circuited_callback1): Move function to libfshelp. (diskfs_S_dir_lookup): Use the function from libfshelp instead. * libdiskfs/fsys-getroot.c (diskfs_S_fsys_getroot): Adapt accordingly. * libdiskfs/trans-callback.c (_diskfs_translator_callback2_fn): Likewise. * libfshelp/fetch-root.c (fshelp_short_circuited_callback1): New function. * libfshelp/fshelp.h (struct fshelp_stat_cookie): New definition. (fshelp_short_circuited_callback1): New prototype. * libnetfs/dir-lookup.c (short_circuited_callback1): Drop function. (netfs_S_dir_lookup): Use the function from libfshelp instead. * libnetfs/fsys-getroot.c (netfs_S_fsys_getroot): Adapt accordingly. * libnetfs/trans-callback.c (_netfs_translator_callback2_fn): Likewise.
