G/C In3270 - always false

Make this compile if pam is present. XXX: this sucks, because we don't
really use PAM here, but libtelnet needs it.

- 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.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.

PR/18984: John Heasley: telnet spins on dead tty

De-register, de-__P. Remove #ifndef __STDC__ parts.
defines.h: Be more careful with braces in macro definitions.

Update from trunk:
Bring the telnet situation back into better shape.  Specifically,
pull in just about all of the differences from the crypto-us telnet
suite (which includes Kerberos 4 and connection encryption support).
Also bring in the Kerberos 5 support from the Heimdal telnet, and
frob a little so that it can work with the non-Heimdal telnet suite.

There is still some work left to do, specifically:
- Add Heimdal's ticket forwarding support to the Berkeley Kerberos 4
  module.
- Add connection encryption support to the Heimdal Kerberos 5
  module.  Hints on this can be taken from the MIT Kerberos 5
  module which still exists in crypto-us.

However, even with the shortcomings listed above, this is a
better situation than using the stock Heimdal telnet suite,
which does not understand the IPSec policy stuff, and is also
based on much older code which contains bugs that we have already
fixed in the NetBSD sources.
