djm@openbsd.org 7c85685760 upstream: switch over to the new authorized_keys options API and 
remove the legacy one.

Includes a fairly big refactor of auth2-pubkey.c to retain less state
between key file lines.

Darren Tucker e0259a82dd Remove do_pam_set_tty which is dead code. 
The callers of do_pam_set_tty were removed in 2008, so this is now dead
code.  bz#2604, pointed out by jjelen at redhat.com.

Darren Tucker 1e8013a17f Remove obsolete CVS $Id from source files. 
Since -portable switched to git the CVS $Id tags are no longer being
updated and are becoming increasingly misleading.  Remove them.

Damien Miller 8bd81e1596 add --with-pam-service to specify PAM service name 
Saves messing around with CFLAGS to do it.

Darren Tucker 01558b7b07 Handle PAM_MAXTRIES from modules. 
bz#2249: handle the case where PAM returns PAM_MAXTRIES by ceasing to offer
password and keyboard-interative authentication methods.  Should prevent
"sshd ignoring max retries" warnings in the log.  ok djm@

It probably won't trigger with keyboard-interactive in the default
configuration because the retry counter is stored in module-private
storage which goes away with the sshd PAM process (see bz#688).  On the
other hand, those cases probably won't log a warning either.

   considered a security exposure).  ok djm@
