timing.c, and hence takes its own responsibility for calling
noise_regular() at regular intervals. Again, this means it will be
called consistently in _all_ the SSH-speaking tools, not just those
in which I remembered to call it!

blink when the window doesn't have focus, we don't schedule blink
timers at that point either.
Infrastructure change: term->has_focus should now not be written
directly from outside terminal.c. Instead, use the function
term_set_focus, which will sort out the blink timers as well.

SSH2, is now handled by the packet dispatch table. Dispatch table
entries are enabled as soon as possible, so that if anyone tries to
(for example) start using a forwarded port before the main shell
session setup has finished, things should work sensibly.
The SSH code is now a hybrid of coroutine-based sequential logic and
table-driven event dispatch, each where it makes the most sense. I'm
rather pleased with it.
Should fix: ext-data-at-start, portfwd-at-start.

data transfer in either direction (whichever comes first), or at
explicit client request (nice idea Jacob). Have tested by lowering
the limits, and it all seems solid enough; in particular, this has
also allowed me to test the behaviour when connection-level data is
received during rekey, and that looks fine too (at least it does
_now_ :-).

which pretty much any module can call to request a call-back in the
future. So terminal.c can do its own handling of blinking, visual
bells and deferred screen updates, without having to rely on
term_update() being called 50 times a second (fixes: pterm-timer);
and ssh.c and telnet.c both invoke a new module pinger.c which takes
care of sending keepalives, so they get sent uniformly in all front
ends (fixes: plink-keepalives, unix-keepalives).

ssh1_protocol() and ssh2_protocol() are now high-level functions
which see _every_ SSH packet and decide which lower-level function
to pass it to. Also, they each support a dispatch table of simple
handler functions for message types which can arrive at any time.
Results are:
- ignore, debug and disconnect messages are now handled by the
dispatch table rather than being warts in the rdpkt functions
- SSH2_MSG_WINDOW_ADJUST is handled by the dispatch table, which
means that do_ssh2_authconn doesn't have to explicitly
special-case it absolutely every time it waits for a response to
its latest channel request
- the top-level SSH2 protocol function chooses whether messages get
funnelled to the transport layer or the auth/conn layer based on
the message number ranges defined in the SSH architecture draft -
so things that should go to auth/conn go there even in the middle
of a rekey (although a special case is that nothing goes to
auth/conn until initial kex has finished). This should fix the
other half of ssh2-kex-data.
[originally from svn r4901]
can keep several of them in parallel. In particular, this allows us
to queue outgoing packets during repeat key exchange, to be actually
sent after the rekey completes.
(This doesn't fully fix ssh2-kex-data; also required is the ability
to handle _incoming_ connection-layer packets during rekey without
exploding.)

structure have been retired. Now all Packet structures are
dynamically allocated. Each rdpkt function allocates one, and it's
freed after being used; and the packet construction functions
allocate them too, and they're freed by the send functions.
`pktin' and `pktout' were ugly. They were _morally_ still global
variables; even though they were replicated per SSH session to
comply with the Mac no-globals requirement, they weren't really in
the _spirit_ of `dynamically allocate your data'.
As a side effect of this change, the `pktout_blanks' and
`pktout_nblanks' fields in the Ssh structure have been moved into
the Packet structure.

- initialise blank mbstate_t using memset rather than an ad-hoc
initialiser.
- expand the OMIT_UTMP ifdefs to enclose a load of entire functions
that would generate `static function never called' warnings if
left as empty shells.
- couple of other fiddly things.

prompt for keyboard-interactive. I suspect we should do the same with that
method (especially given the apparent number of systems that use it for
regular password auth), but in the absence of systems to test against I've
not actually made the change. (I'm worried that the `partial success' field
might not be set correctly in a multi-stage authentication, for instance.)

authentication state, a failed `password' authentication in SSH-2 was
sending us back to trying `none' and `keyboard-interactive' each time
round, which uses up OpenSSH's quota of authentication attempts rather
quickly. Added a check for `cfg.change_username' to the logic which
sends us back to the start.

before is would return success and the empty string. IMO this makes `-batch'
much more useful; before, utilities such as Plink in `-batch' mode would
attempt to plough on using empty strings for usernames, passwords, and so on.
[originally from svn r4832]
pointed out that Plink would attempt to use a zero-length username iff
a remote command was specified (because the FLAG_INTERACTIVE test was
erroneously combined with the no-username test).
I don't think this will break non-interactive use; in the cases which
behave differently, Plink would be attempting to use the empty
username, which was almost certainly wrong, whereas now it will give a
prompt (which can be avoided with -batch as usual).
(Although perhaps we should attempt to use a local username as a guess for
the remote username, as PSCP does? I've not done this.)

line for every single .but file at the bottom of each page of the
HTML PuTTY docs. However, we can't _always_ replace that with a
single SVN revision, because there isn't always one available (SVN
still allows mixed working copies in which some files are
deliberately checked out against a different revision).
Hence, here's a mechanism for doing better. It uses `svnversion .'
to determine _whether_ a single revision number adequately describes
the current directory, and replaces all the version IDs with that if
so. If it can't do that, it uses the version IDs as before.
Also, this allows an explicit version string to be passed on the
make command line which will override _both_ these possibilities, so
that release documentation can be clearly labelled with the release
version number.
