markus@openbsd.org c7d39ac8dc upstream: sshd: switch authentication to sshbuf API; ok djm@

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.

     may be forwarded to a local Unix domain socket and vice versa or

     Thanks also to Ben Hawkes, David Tomaschik, Ivan Fratric, Matthew
     Dempsky and Ron Bowes for a detailed review a few months ago.

     NB. This commit also removes portable OpenSSH support for OpenSSL
     <0.9.8e.

[auth2-none.c auth2.c]
     Make protocol 2 MaxAuthTries behaviour a little more sensible:
     Check whether client has exceeded MaxAuthTries before running
     an authentication method and skip it if they have, previously it
     would always allow one try (for "none" auth).
     Preincrement failure count before post-auth test - previously this
     checked and postincremented, also to allow one "none" try.
     Together, these two changes always count the "none" auth method
     which could be skipped by a malicious client (e.g. an SSH worm)
     to get an extra attempt at a real auth method. They also make
     MaxAuthTries=0 a useful way to block users entirely (esp. in a
     sshd_config Match block).
     Also, move sending of any preauth banner from "none" auth method
     to the first call to input_userauth_request(), so worms that skip
     the "none" method get to see it too.

     makes the pain stop in one easy step
     NB. portable commit contains everything *except* removing includes.h, as
     that will take a fair bit more work as we move headers that are required
     for portability workarounds to defines.h. (also, this step wasn't "easy")
