Summary:                    Use ptsname_r instead of ptsname in telnetd.c
Description: 
The Busybox telnet daemon (networking/telnetd.c) uses ptsname(3) to find
the slave device of a terminal. However apparently at least in some
environments this function fails consistently: it always returns NULL.

The ptsname_r(3) function is a replacement for ptsname() that doesn't
require thread-local storage and is likely to work in more environments,
so I propose that the code be changed to use ptsname_r instead of
ptsname/strcpy or equivalent.
