Add a "MACs" line after "Ciphers" with the default MAC algorithms,

[kex.h mac.c mac.h monitor_wrap.c myproposal.h packet.c ssh.1]
[ssh_config.5 sshd.8 sshd_config.5]
Add a new MAC algorithm for data integrity, UMAC-64 (not default yet,
must specify umac-64@openssh.com). Provides about 20% end-to-end speedup
compared to hmac-md5. Represents a different approach to message
authentication to that of HMAC that may be beneficial if HMAC based on
one of its underlying hash algorithms is found to be vulnerable to a
new attack. http://www.ietf.org/rfc/rfc4418.txt
in conjunction with and OK djm@
[kex.c monitor_wrap.c packet.c mac.h kex.h mac.c]
Preserve MAC ctx between packets, saving 2xhash calls per-packet.
Yields around a 12-16% end-to-end speedup for arcfour256/hmac-md5

[ssh-agent.c]
Remove the signal handler that checks if the agent's parent process
has gone away, instead check when the select loop returns. Record when
the next key will expire when scanning for expired keys. Set the select
timeout to whichever of these two things happens next. With djm@, with &

[sshd_config]
Disable the legacy SSH protocol 1 for new installations via
a configuration override. In the future, we will change the
server's default itself so users who need the legacy protocol
will need to turn it on explicitly
[servconf.c sshd.c]
Move C/R -> kbdint special case to after the defaults have been
loaded, which makes ChallengeResponse default to yes again. This
was broken by the Match changes and not fixed properly subsequently.

bug in OpenSSL 0.9.8e that prevents aes256-ctr, aes192-ctr and arcfour256
ciphers from working correctly (disconnects with "Bad packet length"
errors) as found by Ben Harris. ok djm@
[auth2.c sshd_config.5 servconf.c]
Remove ChallengeResponseAuthentication support inside a Match
block as its interaction with KbdInteractive makes it difficult to
support. Also, relocate the CR/kbdint option special-case code into
servconf. "please commit" djm@, ok markus@ for the relocation.
[ssh-agent.c]
Remove expired keys periodically so they don't remain in memory when
the agent is entirely idle, as noted by David R. Piegdon. This is the
simple fix, a more efficient one will be done later. With markus,
deraadt, with & ok djm.
[sshd.c]
Clear alarm() before restarting sshd on SIGHUP. Without this, if there's
a SIGALRM pending (for SSH1 key regeneration) when sshd is SIGHUP'ed, the
newly exec'ed sshd will get the SIGALRM and not have a handler for it,
and the default action will terminate the listening sshd. Analysis and
patch from andrew at gaul.org.

NULL on some platforms (eg Tru64), which is explicitly permitted by
POSIX. Diagnosis and patch by svallet genoscope.cns.fr.
[monitor_wrap.c servconf.c servconf.h monitor.c sshd_config.5]
Teach Match how handle config directives that are used before
authentication. This allows configurations such as permitting password
authentication from the local net only while requiring pubkey from
offsite. ok djm@, man page bits ok jmc@

library interfaces aren't very helpful. Fix up the DOPR_OUTCH macro
so it works properly and modify its callers so that they don't pre or
post decrement arguments that are conditionally evaluated. While there,
put SNPRINTF_CONST back as it prevents build failures in some
configurations. ok djm@ (for most of it)

bz #1019: some ssh.com versions apparently can't cope with the
