blacklistd has been renamed to blocklistd upstream, and a future
import into FreeBSD will follow that change. Support the new name
as an alias in config files.

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.
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.

deprecated algorithms, which we look for but don't generate.

Upstream did this a long time ago, but we kept DSA and SSH1 in FreeBSD for
reasons which boil down to POLA. Now is a good time to catch up.

"sandbox" instead of "yes". In sandbox mode, the privsep child is unable
to load additional libraries and will therefore crash when trying to take
advantage of crypto offloading on CPUs that support it.

- Revert modifications to loginrec.c, as the upstream version already
does the right thing.
- Fix indentation and whitespace of local changes.

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.

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.
