8998619212 Add support for dynamically adjusted buffers to allow the full use of
the bandwidth of long fat pipes (i.e. 100Mbps+ trans-oceanic or
trans-continental links).  Bandwidth-delay products up to 64MB are
supported.

Also add support (not compiled by default) for the None cypher.  The
None cypher can only be enabled on non-interactive sessions (those
without a pty where -T was not used) and must be enabled in both
the client and server configuration files and on the client command
line.  Additionally, the None cypher will only be activated after
authentication is complete.  To enable the None cypher you must add
-DNONE_CIPHER_ENABLED to CFLAGS via the make command line or in
/etc/make.conf.

This code is a style(9) compliant version of these features extracted
from the patches published at:

http://www.psc.edu/networking/projects/hpn-ssh/

Merging this patch has been a collaboration between me and Bjoern.

0a70456882 Fix Incorrectly formatted ClientHello SSL/TLS handshake messages could
cause OpenSSL to parse past the end of the message.

Note: Applications are only affected if they act as a server and call
SSL_CTX_set_tlsext_status_cb on the server's SSL_CTX. This includes
Apache httpd >= 2.3.3, if configured with "SSLUseStapling On".

905571c031 Remove copyright strings printed at login time via login(1) or sshd(8).
It is not clear to what this copyright should apply, and this is in line
with what other operating systems do.

For ssh specifically, printing of the copyright string is not in the
upstream version so this reduces our FreeBSD-local diffs.

6a599222bb Merge OpenSSL 0.9.8m into head.
This also "reverts" some FreeBSD local changes so we should now
be back to using entirely stock OpenSSL.  The local changes were
simple $FreeBSD$ lines additions, which were required in the CVS
days, and the patch for FreeBSD-SA-09:15.ssl which has been
superseded with OpenSSL 0.9.8m's RFC5746 'TLS renegotiation
extension' support.

b40cdde64c Make OpenSSH work with utmpx.
- Partially revert r184122 (sshd.c). Our ut_host is now big enough to
  fit proper hostnames.

- Change config.h to match reality.

- defines.h requires UTMPX_FILE to be set by <utmpx.h> before it allows
  the utmpx code to work. This makes no sense to me. I've already
  mentioned this upstream.

- Add our own platform-specific handling of lastlog. The version I will
  send to the OpenSSH folks will use proper autoconf generated
  definitions instead of `#if 1'.

Please note that this can't be done while such processes run in jails.

Note: in future it would be interesting to find a way to do that
selectively for any desired proccess (choosen by user himself), probabilly
via a ptrace interface or whatever.
