7235884959 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.

291f74b116 Try to check whether each key file exists before adding it, and bail out
if we didn't find any of them.  This reduces log spam about key files for
deprecated algorithms, which we look for but don't generate.

7b7845b35c Remove DSA from default cipher list and disable SSH1.
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.

a636f8f94f Use proper CHAN_TCP_PACKET_DEFAULT for agent forwarding when HPN disabled.
The use of CHAN_TCP_WINDOW_DEFAULT here was fixed in upstream OpenSSH
in CVS 1.4810, git 5baa170d771de9e95cf30b4c469ece684244cf3e:

  - dtucker@cvs.openbsd.org 2007/12/28 22:34:47
    [clientloop.c]
    Use the correct packet maximum sizes for remote port and agent forwarding.
    Prevents the server from killing the connection if too much data is queued
    and an excessively large packet gets sent.  bz #1360, ok djm@.

The change was lost due to the the way the original upstream HPN patch
modified this code. It was re-adding the original OpenSSH code and never
was properly fixed to use the new value.

fc833dce1b Add a pre-merge script which reverts mechanical changes such as added
$FreeBSD$ tags and man page dates.

Add a post-merge script which reapplies these changes.

Run both scripts to normalize the existing code base.  As a result, many
files which should have had $FreeBSD$ tags but didn't now have them.

Partly rewrite the upgrade instructions and remove the now outdated
list of tricks.
