07fdb4201a More work on CVE-2019-0053. 
Telnet protocol messages must remain sane at all costs, instead of
being truncated because indata was oversized.  Some additional cases
of insufficient buffer declaration are corrected.

ec8c9a31b4 telnetd: Premature connection closure. 
A change, part of 0b7e8687, but secondary to its
intention, turned out to cause service rejects during
conditions akin to connection flooding.  Revert this
particular part to gain established, good behaviour
on GNU/Linux.
Reported in `bug-inetutils/2015-07/msg00006.html'.

239949170f telnetd: Incomplete processing of PTY data. 
It may happen that an incoming SIGCHLD intervenes with the transfer
of the last few bytes from the PTY of the child process to the net
stream servicing the remote client with response.  Improved signal
handling of SIGCHLD prevents this loss.
