Avoid overlapping addresses to stpcpy calls in nscd (BZ #16760)
Calls to stpcpy from nscd netgroups code will have overlapping source and destination when all three values in the returned triplet are non-NULL and in the expected (host,user,domain) order. This is seen in valgrind as: ==3181== Source and destination overlap in stpcpy(0x19973b48, 0x19973b48) ==3181== at 0x4C2F30A: stpcpy (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==3181== by 0x12567A: addgetnetgrentX (string3.h:111) ==3181== by 0x12722D: addgetnetgrent (netgroupcache.c:665) ==3181== by 0x11114C: nscd_run_worker (connections.c:1338) ==3181== by 0x4E3C102: start_thread (pthread_create.c:309) ==3181== by 0x59B81AC: clone (clone.S:111) ==3181== Fix this by using memmove instead of stpcpy.
