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.
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.

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.

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.

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

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.

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.
