[ssh.c]
close any extra file descriptors inherited from parent at start and
reopen stdin/stdout to /dev/null when forking for ControlPersist.
prevents tools that fork and run a captive ssh for communication from
failing to exit when the ssh completes while they wait for these fds to
close. The inherited fds may persist arbitrarily long if a background
mux master has been started by ControlPersist. cvs and scp were effected
by this.

openbsd-compat/openbsd-compat.h openbsd-compat/strptime.c] Add strptime to
the compat library which helps on platforms like old IRIX. Based on work
by djm, tested by Tom Christensen.

regress/test-exec.sh] Under certain conditions when testing with sudo
tests would fail because the pidfile could not be read by a regular user.
"cat: cannot open ...../regress/pidfile: Permission denied (error 13)"
Make sure cat is run by $SUDO. no objection from me. djm@

[channels.c]
Fix a trio of bugs in the local/remote window calculation for datagram
data channels (i.e. TunnelForward):
Calculate local_consumed correctly in channel_handle_wfd() by measuring
the delta to buffer_len(c->output) from when we start to when we finish.
The proximal problem here is that the output_filter we use in portable
modified the length of the dequeued datagram (to futz with the headers
for !OpenBSD).
In channel_output_poll(), don't enqueue datagrams that won't fit in the
peer's advertised packet size (highly unlikely to ever occur) or which
won't fit in the peer's remaining window (more likely).
In channel_input_data(), account for the 4-byte string header in
datagram packets that we accept from the peer and enqueue in c->output.

[ssh.1 ssh_config.5 sshd.8]
Remove mentions of weird "addr/port" alternate address format for IPv6

[clientloop.c readconf.c readconf.h ssh.c ssh_config.5]
add a "ControlPersist" option that automatically starts a background
ssh(1) multiplex master when connecting. This connection can stay alive
indefinitely, or can be set to automatically close after a user-specified
duration of inactivity. bz#1330 - patch by dwmw2 AT infradead.org, but
further hacked on by wmertens AT cisco.com, apb AT cequrux.com,
martin-mindrot-bugzilla AT earth.li and myself; "looks ok" markus@

[ssh-rsa.c]
more timing paranoia - compare all parts of the expected decrypted
data before returning. AFAIK not exploitable in the SSH protocol.

implement a timing_safe_cmp() function to compare memory without leaking
timing information by short-circuiting like memcmp() and use it for
some of the more sensitive comparisons (though nothing high-value was
readily attackable anyway); "looks ok" markus@

[ssh.c ssh_config.5]
expand %h to the hostname in ssh_config Hostname options. While this
sounds useless, it is actually handy for working with unqualified
hostnames:
Host *.*
Hostname %h
Host *
Hostname %h.example.org
