each backend now stores all its internal variables in a big struct,
and each backend function gets a pointer to this struct passed to
it. This still isn't the end of the work - lots of subsidiary things
still use globals, notably all the cipher and compressor modules and
the X11 forwarding authentication stuff. But ssh.c itself has now
been transformed, and that was the really painful bit, so from here
on it all ought to be a sequence of much smaller and simpler pieces
of work.

terminal.c was apparently relying on implicit initialisation to
zero, and also I've removed the backends' dependency on terminal.h
by having terminal sizes explicitly passed in to back->size().

all the global and function-static variables out of terminal.c into
a dynamically allocated data structure. Note that this does not yet
confer the ability to run more than one of them in the same process,
because other things (the line discipline, the back end) are still
global, and also in particular the address of the dynamically
allocated terminal-data structure is held in a global variable
`term'. But what I've got here represents a reasonable stopping
point at which to check things in. In _theory_ this should all still
work happily, on both Unix and Windows. In practice, who knows?

CONNECT, but contains an extensible framework to allow other
proxies. Apparently SOCKS and ad-hoc-telnet-proxy are already
planned (the GUI mentions them already even though they don't work
yet). GUI includes full configurability and allows definition of
exclusion zones. Rock and roll.

process. This is functional in SSH, and vestigial (just returns 0)
in the other three protocols. Plink's Windows exit code is now
determined by the remote process exit code, which should make it
more usable in scripting applications. Tested in both SSH1 and SSH2.

by ceasing to listen on input channels if the corresponding output
channel isn't accepting data. Has had basic check-I-didn't-actually-
break-anything-too-badly testing, but hasn't been genuinely tested
in stress conditions (because concocting stress conditions is non-
trivial).

send Telnet special sequences (Interrupt Process, Suspend, Erase
Char, End Of Line) instead of their ASCII equivalents. In particular
Return -> Telnet End Of Line is _always_ enabled irrespective of the
configuration, while the others are optional. Also in this patch, an
entertainingly ghastly use of `switch' to allow literal ^M^J to do
the same thing as magic-^M (the Return key) when in Raw protocol.

version allows you to specify, per socket, which sockets receive OOB
data in-line (so that you know what was before the mark and what was
after) and which receive it out of line (so it's really a one-byte
out-of-band facility rather than discard-to-mark). This reflects the
fact that rlogin appears to make more sense in the latter mode, and
telnet in the former. This patch makes rlogin work right for me.
[originally from svn r921]
multiple switchable line disciplines, we now have a single unified
one which changes its behaviour based on option settings. Each
option setting can be suggested by the back end and/or the terminal
handler, and can be forcibly overridden by the configuration. Local
echo and local line editing are separate, independently switchable,
options.

automatic fatalbox(). Instead, the error is passed to the receiver
routine, which can decide just how fatal the problem really is.

advantages:
- protocol modules can call sk_write() without having to worry
about writes blocking, because blocking writes are handled in the
abstraction layer and retried later.
- `Lost connection while sending' is a thing of the past.
- <winsock.h> is no longer needed in most modules, because
"putty.h" doesn't have to declare `SOCKET' variables any more,
only the abstracted `Socket' type.
- select()-equivalent between multiple sockets will now be handled
sensibly, which opens the way for things like SSH port
forwarding.

use when they have data from the network. Replaces the utterly daft
inbuf / inbuf_head / term_out() interface, which only made sense
when feeding to terminal.c. (terminal.c now implements
from_backend() as a small function that gateways to the old
interface.)
As a side effect, from_backend() also has an `is_stderr' parameter,
so scp can once again separate the server's pronouncements on stderr
from the actual protocol progress on stdout.

- cope with strange WinSock wrappers not supporting SIOCATMARK
- define yet more terminal compatibility modes
- support UK-ASCII (just like US-ASCII but # is a sterling sign)
- support connection keepalives at a configurable interval
[originally from svn r692]
- `local ldisc' config option now switches between PuTTY's original
behaviour when off (aggressively start negotiations, never use
local line discipline) and Unix telnet's off-port-25 behaviour
when on (wait to be negotiated with, toggle local line discipline
when TELOPT_ECHO changes)
- SYNCH handling has been improved again, though it may still be
broken due to WinSock being irretrievably pants
[originally from svn r420]
now sends NVT `NL' (CR,LF) instead of NVT `CR' (CR,NUL). Unix
telnetd apparently cares not a jot for the difference, but others do.
[originally from svn r407]
- ^E answerback is now `PuTTY'.
- The framework is now in place for the scrollback to reset to
bottom on display _or_ keyboard events _or_ both. An actual
configurable option isn't yet present, but most of the code is in
place.
- Try to deal with the problems where incoming data gets dropped
after decoding but before display.
- Scrollback behaviour has changed: instead of keying it off
`scroll' versus `delete top line', things now go into the
scrollback from _either_ of those but only if the primary screen
is selected. Should fix problems with `less' and talkers.
- must_update variable has gone because rdb correctly observed that
it didn't seem to be doing a great deal :-)
[originally from svn r328]
- NetHack keypad mode (Shift only works with NumLock off)
- Alt-Space handling (best I could manage; not too bad considering)
- Event Log rather than Telnet Negotiation Log
[originally from svn r284]
- Stop using the identifier `environ' as some platforms make it a macro
- Fix silly error box at end of connection in FWHACK mode
- Fix GPF on maximise-then-restore
- Use SetCapture to allow drag-selecting outside the window
- Correctly update window title when iconic and in win_name_always mode
