First, make absolute times unsigned. This means that it's safe to
depend on their overflow behaviour (which is undefined for signed
integers). This requires a little extra care in handling comparisons,
but I think I've correctly adjusted them all.
Second, functions registered with schedule_timer() are guaranteed to be
called with precisely the time that was returned by schedule_timer().
Thus, it's only necessary to check these values for equality rather than
doing risky range checks, so do that.
The timing code still does lots that's undefined, unnecessary, or just
wrong, but this is a good start.

UTF-16 support. High Unicode characters in the terminal are now
converted back into surrogates during copy and draw operations, and
the Windows drawing code takes account of that when splitting up the
UTF-16 string for display. Meanwhile, accidental uses of wchar_t have
been replaced with 32-bit integers in parts of the cross-platform code
which were expecting not to have to deal with UTF-16.

so we should ensure we treat it the same way as other WM_SIZEs that
show up during that time: set the width and height in conf, and set
the flag to have that width and height enacted on WM_EXITSIZEMOVE.
Fixes a bug in which dragging a PuTTY window directly from the Win7
snapped-to-half-screen position to the snapped-to-maximised state
would leave the terminal in the pre-snapped size.

allocated type.
The main reason for this is to stop it from taking up a fixed large
amount of space in every 'struct value' subunion in conf.c, although
that makes little difference so far because Filename is still doing
the same thing (and is therefore next on my list). However, the
removal of its arbitrary length limit is not to be sneezed at.

data channels. Should comprehensively fix 'half-closed', in principle,
though it's a big and complicated change and so there's a good chance
I've made at least one mistake somewhere.
All connections should now be rigorous about propagating end-of-file
(or end-of-data-stream, or socket shutdown, or whatever) independently
in both directions, except in frontends with no mechanism for sending
explicit EOF (e.g. interactive terminal windows) or backends which are
basically always used for interactive sessions so it's unlikely that
an application would be depending on independent EOF (telnet, rlogin).
EOF should now never accidentally be sent while there's still buffered
data to go out before it. (May help fix 'portfwd-corrupt', and also I
noticed recently that the ssh main session channel can accidentally
have MSG_EOF sent before the output bufchain is clear, leading to
embarrassment when it subsequently does send the output).

Conf serialisation done with great care and working just fine, and

[originally from svn r9237]
'Config' in putty.h, which stores all PuTTY's settings and includes an
arbitrary length limit on every single one of those settings which is
stored in string form. In place of it is 'Conf', an opaque data type
everywhere outside the new file conf.c, which stores a list of (key,
value) pairs in which every key contains an integer identifying a
configuration setting, and for some of those integers the key also
contains extra parts (so that, for instance, CONF_environmt is a
string-to-string mapping). Everywhere that a Config was previously
used, a Conf is now; everywhere there was a Config structure copy,
conf_copy() is called; every lookup, adjustment, load and save
operation on a Config has been rewritten; and there's a mechanism for
serialising a Conf into a binary blob and back for use with Duplicate
Session.
User-visible effects of this change _should_ be minimal, though I
don't doubt I've introduced one or two bugs here and there which will
eventually be found. The _intended_ visible effects of this change are
that all arbitrary limits on configuration strings and lists (e.g.
limit on number of port forwardings) should now disappear; that list
boxes in the configuration will now be displayed in a sorted order
rather than the arbitrary order in which they were added to the list
(since the underlying data structure is now a sorted tree234 rather
than an ad-hoc comma-separated string); and one more specific change,
which is that local and dynamic port forwardings on the same port
number are now mutually exclusive in the configuration (putting 'D' in
the key rather than the value was a mistake in the first place).
One other reorganisation as a result of this is that I've moved all
the dialog.c standard handlers (dlg_stdeditbox_handler and friends)
out into config.c, because I can't really justify calling them generic
any more. When they took a pointer to an arbitrary structure type and
the offset of a field within that structure, they were independent of
whether that structure was a Config or something completely different,
but now they really do expect to talk to a Conf, which can _only_ be
used for PuTTY configuration, so I've renamed them all things like
conf_editbox_handler and moved them out of the nominally independent
dialog-box management module into the PuTTY-specific config.c.

rectangle into smaller ones: it doesn't work any more, since the new
variable-pitch code can now call general_textout() with a larger
clipping rectangle than the text it's meant to be displaying. Instead,
general_textout() now uses the same semantics as the next loop up in
do_text_internal(): the first piece of text it displays uses the
opacity setting passed in, which blanks the entire clipping rectangle
if necessary, and then subsequent overlays are non-opaque. And the
same clipping rectangle is used throughout.

array to ExtTextOut:
- move it inside the new big loop (this should fix a potential bug
whereby the DBCS handling altered some elements of it but the loop
did not actually step along it)
- initialise it more sensibly
- rename it to lpDx rather than IpDx, since as far as I can tell the
latter name was derived from a misreading of the former in the
Windows API docs.
[originally from svn r9066]
pass null lpDx, because general_textout depends on it being filled in.
Instead we null it out in the calls to subroutines _from_
general_textout.

Done in much the same way as it is in the GTK front end: the character
cell width is determined using the font's digits (which seems to give
generally not-too-offensive spacing in most cases, at the expense of
Ms and Ws typically overhanging a bit into adjacent cells) and each
character is centred in its cell. Overhangs never leave permanent
droppings on the window, because the existing work done in r5003
handles them just fine even in this stressful scenario.
There's a hacky new checkbox in the Appearance panel to make
variable-pitch fonts appear in the font selector (they still don't by
default, because I still think it's _usually_ not What You Want); the
checkbox state is not actually stored as part of a saved session, but
it should be automatically ticked when reloading a session that's got
a variable pitch font selected.
(I'm half-expecting a potential flurry of requests for this feature in
the wake of http://xkcd.com/840/ , so I thought I'd pre-empt them :-)

I'm not sure whether I broke this in the recent revamp or whether it
was always broken, but: transitions in and out of full-screen mode
work by first maximising or restoring the window, which triggers a
WM_SIZE, whose handler then fiddles with the window style to disable
or re-enable all the furniture, which in turn triggers a recursive
WM_SIZE. The trouble is, after returning from the handler for the
inner WM_SIZE, the rest of the outer handler runs, and its client area
size is now out of date.
So I've added a flag which is set when a resize is handled 'properly',
so that after returning from the inner WM_SIZE handler the outer one
knows not to try to redo badly work that's already been done well.

jump list is updated every time a saved session is loaded, and shows
the last few launchable saved sessions (i.e. not those like Default
Settings) that were loaded. Also, if Pageant or PuTTYgen or both is in
the same directory as the PuTTY binary, the jump list will present
links to launch those too.

maximised state, we must be sure to disable the window offset used to
centre the terminal in cases where the window is non-negotiably the
wrong size (e.g. maximised). Hence we must call reset_window after our
terminal resize.
[originally from svn r9044]
restoring a maximised window.
Failure to do this was noticeable in the following scenario (again
using Aero UI enhancements):
1. resize window using topmost resize handle, and move pointer to top
of screen which 'maximises' the window vertically
2. now maximise the window properly using the maximise button in top
right
3. now restore. Notepad restores to its position before step 1,
because Aero remembers that position for the purpose, but PuTTY
thinks it knows better. Only now it doesn't any more.
[originally from svn r9041]
Firstly, maximise and restore events were expected never to occur
during an interactive resize process (i.e. between WM_ENTERSIZEMOVE
and WM_EXITSIZEMOVE), but in fact Aero now allows this to happen if
you move the pointer to the top of the screen while dragging the
window.
Secondly, plain old WM_SIZE events were expected never to occur
_outside_ interactive resizes, but Aero permits that too (e.g.
Windows-left and Windows-right), and also third-party window
repositioning tools will send these.

case of double-width text (ESC # 3, ESC # 4, ESC # 6), because the
string passed to it was not truncated to the same width as the
clipping rectangle. (In fact, it _can't_ reliably be, in the case
where the window width is odd.) So instead we just assert that we
managed to _at least_ fill the clipping rectangle, not that we
exactly filled it.
The problem is easily reproduced by sending ESC # 8 (fill the screen
with Es) followed by ESC # 3. It doesn't typically happen, though,
if you _manually_ fill the screen with Es, because in that case
PuTTY's terminal buffer ends up being filled with CSET_ACP | 'E' or
similar, which means that general_textout() never gets called
because one of the other branches of do_text_internal() does the
work instead. ESC # 8 will fill the terminal buffer with genuine
_Unicode_ 'E' characters, which exercises the failing code path.
