Modified Files:
	src/usr.bin/telnet: commands.c externs.h network.c sys_bsd.c telnet.c
	    terminal.c

Log Message:
- deal with a dead tty in ttyflush() by cleaning-up and exiting instead of
  returning a failure code and processing that all the way up the stack.
- deal with a dead peer similarly and do it without setjmp/longjmp() (at
  christos' request).

These fix bin/20304 and my own observations when the remote abruptly closes
the connection.
