mode ever failed to do this, and only Plink actually had a problem
with it, so this didn't become obvious for a while. rlogin mode is
fixed, and all implementations of from_backend() now contain an
assertion so that we should spot errors of this type more quickly in
future.

sick of recompiling to enable packet dumps. SSH packet dumping is
now provided as a logging option, and dumps to putty.log like all
the other logging options. While I'm at it I cleaned up the format
so that packet types are translated into strings for easy browsing.
POSSIBLE SIDE EFFECT: in the course of this work I had to re-enable
the SSH1 packet length checks which it turns out hadn't actually
been active for some time, so it's possible things might break as a
result. If need be I can always disable those checks for the 0.52
release and think about it more carefully later.

uses to manipulate the window (minimise, maximise, front, back,
move, resize) and report things about the window (is it minimised or
maximised, how big is it, what's its title). Missing are ESC[4;X;Yt
(resize to a specified pixel size; our resize code doesn't like it)
and ESC[19;X;Yt (report size of _screen_ in _characters_, which it
isn't even obvious how to do when you've got a variable font size).

line break was created by wrapping. (Equivalently, if the selection
would _paste_ as a single word without a newline in the middle, then
it will _select_ in the same way.)

9, then did ANSI Delete Line on line 10, the selection highlight
would move up a line even though it wasn't over any text that
actually moved. Easy to reproduce in the likes of vi. Trivial fix.

wraparound, not referencing vbell_timeout if in_vbell==FALSE, that
sort of thing. I doubt it'll fix the reported problems with screen
vbells, since none of the failure modes I've just prevented looked
all that probable to me, but it's nice to have extra robustness
anyway.

term_out() can in turn call ldisc_send() which calls back to
from_backend() when local echo is enabled. This was giving rise to
crazy re-entrancy stuff and stack overflows. Instead from_backend()
deposits its data in a bufchain which term_out() empties the next
time it's called.

fiddle with the widths of characters in DBCS screen fonts, and (the
big one) one to enable a mode in which resizing the window locks the
terminal size and lets the font change, instead of vice versa. That
should shut up a few feature requests!

characters that failed the UTF-8 canonicality rules were being sent
to the session log twice. Sounds trivial, but I bet it'd have
confused anyone who turned on session logging precisely to track
down a canonicality bug :-)

mouse tracking is enabled. (This can be turned off if your app
really wants Shift+mouse, but it defaults to on for general
usefulness.)

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).

it out. A line was removed from the scrollback, cleared, and placed
at the bottom of the screen. Fine, except that the clearing process
assumed the line was the right length already, and thanks to lazy
resizing this wasn't necessarily the case. Segfaults and memory
corruption ensued.)

possible and we have a single unified means of trying to display any
Unicode code point. Instead of the various ad-hoc translation modes
we had before, we now have a single `codepage' option which allows
us to treat the incoming (and outgoing) text as any given character
set, and locally we map that to Unicode and back.
[originally from svn r1110]
requires fix_cpos() to be called after it (otherwise cpos might point
to a line that isn't where you remember it being), and a mis-aimed
incpos() was causing forward selection dragging not to include the
char under the mouse. Both fixed.

configurable bell overload handling. Thanks to Robert de Bath for
galvanising me into doing this, but I've had to rip most of his code
out and redo it myself...

now to translate them into poor man's characters (+--+ and |). We also
have an option to disable this (and map line drawing characters to the
corresponding ASCII code as before). Thanks to Robert de Bath.

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.

character if we were wrapping, not whether we _will_ wrap next
character. Makes for saner behaviour with vertical-line cursor and
also when changing autowrap mode while on rightmost column. Does
entail small behavioural changes to backspace and destructive-
backspace when in rightmost column with Auto Wrap off, but I don't
think they should be catastrophic, or indeed that there's a well
defined Right Behaviour.

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.
[originally from svn r744]
- Robert de Bath's Compose key is now off by default and configurable on
- The ages-old controversy over whether ALT by itself should bring the
System menu up is now controllable by a config option
- You can now independently configure whether scrollback resets on a
keypress _and_ whether it resets on screen activity.

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.
[originally from svn r729]
- 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

ATTR_BLINK (as bold background) and VT52 support. Plus a
compatibility tracking system whereby all escape sequences can be
disabled for a pure-VT102 compatibility mode or other levels.

apparently defined behaviour for _all_ CSI-type sequences that ESC[Q
should be equivalent to ESC[0Q. Which is a pain in the wossname and
not a sane way to do it, but if the standards say it then I suppose
... :-(
[originally from svn r406]
- ^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]
- 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
