2a01feabb3 openssh: cherry-pick OpenSSL 1.1.1 compatibility
Compatibility with existing OpenSSL versions is maintained.

Upstream commits:
482d23bcac upstream: hold our collective noses and use the openssl-1.1.x
48f54b9d12 adapt -portable to OpenSSL 1.1x API
86e0a9f3d2 upstream: use only openssl-1.1.x API here too
a3fd8074e2 upstream: missed a bit of openssl-1.0.x API in this unittest
cce8cbe0ed Fix openssl-1.1 fallout for --without-openssl.

Trivial conflicts in sshkey.c and test_sshkey.c were resolved.

Connect libressl-api-compat.c to the build, and regenerate config.h

4f52dfbb8d Upgrade to OpenSSH 7.6p1. This will be followed shortly by 7.7p1.
This completely removes client-side support for the SSH 1 protocol,
which was already disabled in 12 but is still enabled in 11.  For that
reason, we will not be able to merge 7.6p1 or newer back to 11.

342b8b88ba Refine and update blacklist support in sshd
Adjust notification points slightly to catch all auth failures,
rather than just the ones caused by bad usernames.

Modify notification point for bad usernames to send new type of
BLACKLIST_BAD_USER. (Support in libblacklist will be forthcoming soon.)
Add guards to allow library headers to expose the enum of action values.

b2af61ec69 Add refactored blacklist support to sshd
Change the calls to of blacklist_init() and blacklist_notify to be
macros defined in the blacklist_client.h file.  This avoids
the need for #ifdef USE_BLACKLIST / #endif except in the
blacklist.c file.

Remove redundent initialization attempts from within
blacklist_notify - everything always goes through
blacklistd_init().

Added UseBlacklist option to sshd, which defaults to off.
To enable the functionality, use '-o UseBlacklist=yes' on
the command line, or uncomment in the sshd_config file.

repeat performance by introducing a script that runs configure with and
without Kerberos, diffs the result and generates krb5_config.h, which
contains the preprocessor macros that need to be defined in the Kerberos
case and undefined otherwise.

8c0260d62b OpenSSH: allow VersionAddendum to be used again
Prior to this, setting VersionAddendum will be a no-op: one will
always have BASE_VERSION + " " + VERSION_HPN for VersionAddendum
set in the config and a bare BASE_VERSION + VERSION_HPN when there
is no VersionAddendum is set.

HPN patch requires both parties to have the "hpn" inside their
advertized versions, so we add VERSION_HPN to the VERSION_BASE
if HPN is enabled and omitting it if HPN is disabled.

VersionAddendum now uses the following logics:
 * unset (default value): append " " and VERSION_ADDENDUM;
 * VersionAddendum is set and isn't empty: append " "
   and VersionAddendum;
 * VersionAddendum is set and empty: don't append anything.

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.

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'.

7a7043c787 Avoid sshd, cron, syslogd and inetd to be killed under high-pressure swap
environments.
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.

0aeb000d7b At some point, construct_utmp() was changed to use realhostname() to fill
in the struct utmp due to concerns about the length of the hostname buffer.
However, this breaks the UseDNS option.  There is a simpler and better
solution: initialize utmp_len to the correct value (UT_HOSTSIZE instead of
MAXHOSTNAMELEN) and let get_remote_name_or_ip() worry about the size of the
buffer.

d4af9e693f Upgrade to OpenSSH 5.1p1.
I have worked hard to reduce diffs against the vendor branch.  One
notable change in that respect is that we no longer prefer DSA over
RSA - the reasons for doing so went away years ago.  This may cause
some surprises, as ssh will warn about unknown host keys even for
hosts whose keys haven't changed.
