4e2eb78eca Add code for being compatible with ssh.com's krb5 authentication. 
It is done by using the same ssh messages for v4 and v5 authentication
(since the ssh.com does not now anything about v4) and looking at the
contents after unpacking it to see if it is v4 or v5.
Based on code from Björn Grönvall <bg@sics.se>

94cb603894 Patches backported from later development version of OpenSSH which prevent 
(instead of just mitigating through connection limits) the Bleichenbacher
attack which can lead to guessing of the server key (not host key) by
regenerating it when an RSA failure is detected.

a121b36822 Fix a long-standing bug that resulted in a dropped session sometimes 
when an X11-forwarded client was closed.  For some reason, sshd didn't
disable the SIGPIPE exit handler and died a horrible death (well, okay,
a silent death really).  Set SIGPIPE's handler to SIG_IGN.

ab6b35a1d6 Update to OpenSSH 2.3.0 with FreeBSD modifications. OpenSSH 2.3.0 
new features description elided in favor of checking out their
website.

Important new FreeBSD-version stuff: PAM support has been worked
in, partially from the "Unix" OpenSSH version, and a lot due to the
work of Eivind Eklend, too.

This requires at least the following in pam.conf:

sshd    auth    sufficient      pam_skey.so
sshd    auth    required        pam_unix.so                     try_first_pass
sshd    session required        pam_permit.so

163406c6e5 In env_destroy(), it is a bad idea to env_swap(self, 0) to switch 
back to the original environ unconditionally.  The setting of the
variable to save the previous environ is conditional; it happens when
ENV.e_committed is set.  Therefore, don't try to swap the env back
unless the previous env has been initialized.

458b9e5882 Repair a broken conflict resolution in r1.2 which had the effect of nullifying 
the login_cap and login.access checks for whether a user/host is allowed
access to the system for users other than root. But since we currently don't
have a similar check in the ssh2 code path anyway, it's um, "okay".
