Jacob Nevins 5aa719d16e Consistently use a single notation to refer to SSH protocol versions, as
discussed. Use Barrett and Silverman's convention of "SSH-1" for SSH protocol
version 1 and "SSH-2" for protocol 2 ("SSH1"/"SSH2" refer to ssh.com
implementations in this scheme). <http://www.snailbook.com/terms.html>

Simon Tatham f73fcb0424 Add asynchronous callback capability to the askappend() alert box.
This was harder than verify_ssh_host_key() and askalg() put
together, because:
 (a) askappend() can be called at any time, since it's a side effect
     of data-logging functions. Therefore there can be an unfinished
     askappend() alert at any time, and hence the OS X front end has
     to be prepared to _queue_ other alerts which occur during that
     time.
 (b) logging.c has to do something with data that comes in while
     it's waiting for an answer to askappend(). It buffers it until
     it knows what the user wants done with it. This involved
     something of a reorganisation of logging.c.

Simon Tatham 8574822b9b Revamp interface to verify_ssh_host_key() and askalg(). Each of them
now returns an integer: 0 means cancel the SSH connection and 1
means continue with it. Additionally, they can return -1, which
means `front end has set an asynchronous alert box in motion, please
wait to be called back with the result', and each one is passed a
callback function pointer and context for this purpose.

I have not yet done the same to askappend() yet, because it will
take a certain amount of reorganisation of logging.c.

Importantly, this checkin means the host key dialog box now works on
OS X.

Jacob Nevins c9116974ac The terminal window can now indicate that PuTTY is busy in various ways, by
changing its mouse pointer. Currently this is only used in the (slightly-
arbitrarily-defined) "heavy" bits of SSH-2 key exchange. We override pointer
hiding while PuTTY is busy, but preserve pointer-hiding state.

Not yet implemented on the Mac.

Also switch to frobbing window-class cursor in Windows rather than relying on
SetCursor().

Jacob Nevins 3c98d6e60d Add a preference list for SSH-2 key exchange algorithms, on a new "Kex" panel
(which will gain more content anon).

Retire BUG_SSH2_DH_GEX and add a backwards-compatibility wart, since we never
did find a way of automatically detecting this alleged server bug, and in any
case there was only ever one report (<3D91F3B5.7030309@inwind.it>, FWIW).

Also generalise askcipher() to a new askalg() (thus touching all the
front-ends).

I've made some attempt to document what SSH key exchange is and why you care,
but it could use some review for clarity (and outright lies).

Simon Tatham 7ecf13564a New timing infrastructure. There's a new function schedule_timer()
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).

Jacob Nevins 739de21c6d console_get_line() returns failure iff console_batch_mode is set, whereas
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.

Jacob Nevins 98028c746f X forwarding changes:
- new function platform_get_x_display() to find a sensible local display.
   On Unix, the Gtk apps weren't taking account of --display when
   determining where to send forwarded X traffic.
 - explicitly document that leaving X display location blank in config tries
   to do something sensible (and that it's now blank by default)
 - don't override X11Display setting in plink, since that's more properly
   done later

Simon Tatham 2d1287b9ca Added a command-line key generation tool. Currently builds and runs
on Linux, but the (very few) platform-specific bits are already
abstracted out of the main code, so it should port to other
platforms with a minimum of fuss.

Simon Tatham 66fa6f320e And just to prove that psftp.c really is now platform-independent
... here's a Unix port of PSFTP. Woo. (Oddly PSCP looks to be
somewhat harder; there's more Windows code interleaved than there
was in PSFTP.)

Simon Tatham 6bb121ecb9 Colin's const-fixing Patch Of Death. Seems to build fine on Windows
as well as Unix, so it can go in.

Simon Tatham 3bd0415579 Turned the old `Telnet Command' System-submenu into a more general
`Special Command' menu, in which any backend can place its own list
of magical things the user might want to ask the backend to do. In
particular I've implemented the recently proposed "break" extension
in SSH2 using this mechanism.
NB this checkin slightly breaks the Mac build, since it needs to
provide at least a stub form of update_specials_menu().

Simon Tatham f26b7aa0d3 Created new data types `Filename' and `FontSpec', intended to be
opaque to all platform-independent modules and only handled within
per-platform code. `Filename' is there because the Mac has a magic
way to store filenames (though currently this checkin doesn't
support it!); `FontSpec' is there so that all the auxiliary stuff
such as font height and charset and so on which is needed under
Windows but not Unix can be kept where it belongs, and so that I can
have a hope in hell of dealing with a font chooser in the forthcoming
cross-platform config box code, and best of all it gets the horrid
font height wart out of settings.c and into the Windows code where
it should be.
The Mac part of this checkin is a bunch of random guesses which will
probably not quite compile, but which look roughly right to me.
Sorry if I screwed it up, Ben :-)

Simon Tatham 520f716dec Just like under Windows, cleanup_exit() shouldn't need to check
before calling random_save_seed().

Simon Tatham 1b5cb7adf6 Each platform's implementation of askappend() is no longer required
to consult cfg.logxfovr, because it gets done once in logging.c.
askappend() is now called only when a question _really_ needs to be
asked of the user. Also in this checkin, cleanup_exit() in console.c
no longer consults cfg.protocol to decide whether to save the random
seed, because random_save_seed() can make that decision for itself
and do it better.

Simon Tatham 317180ed49 First attempt at a Unix port of Plink. Seems to basically work;
doesn't yet use the SSH agent, no way to specify arbitrary config
options, no manpage yet, couple of other fiddly things need doing,
but it makes SSH connections and doesn't fall over horribly so I say
it's a good start. Now to run it under valgrind...
