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.

0999bc4881 Re-apply part of r311585 which was inadvertantly reverted in the upgrade 
to 7.3p1.  The other part (which adds -DLIBWRAP to sshd's CFLAGS) is
still in place.

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.

144a80bd9a 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.

9ded33068e 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.
