binaries. This step splits sshd into a listener and a session binary. More
splits are planned.
After this changes, the listener binary will validate the configuration,
load the hostkeys, listen on port 22 and manage MaxStartups only. All
session handling will be performed by a new sshd-session binary that the
listener fork+execs.
This reduces the listener process to the minimum necessary and sets us
up for future work on the sshd-session binary.

NB. if you're updating via source, please restart sshd after installing,
otherwise you run the risk of locking yourself out.

We've previously removed a lot of the really old compatibility code,
and with it went the need to include compat.h in most of the files that
have it.

allow authentication methods to have one additional name beyond their
primary name.
allow lookup by this synonym
Use primary name for authentication decisions, e.g. for
PermitRootLogin=publickey
Pass actual invoked name to the authmethods, so they can tell whether they
were requested via the their primary name or synonym.

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

Add support for Unix domain socket forwarding. A remote TCP port
may be forwarded to a local Unix domain socket and vice versa or
both ends may be a Unix domain socket. This is a reimplementation
of the streamlocal patches by William Ahern from:

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.
Bug #892: Send messages from failing PAM account modules to the client via
SSH2_MSG_USERAUTH_BANNER messages. Note that this will not happen with
SSH2 kbdint authentication, which need to be dealt with separately. ok djm@
