Clip the 'lines' parameter to scroll() at the size of the scroll
window. scroll() iterates that many times, so this prevents a tedious
wait if you give a very large parameter to ESC[L or ESC[M, for
example.

A side effect is that very large requests for upward scrolling in a
context that affects the scrollback will not actually wipe out the
whole scrollback: instead they push just the current lines of the
screen into the scrollback, and don't continue on to fill it up with
endless boring blank lines. I think this is likely to be more useful
in general, since it avoids wiping out lots of useful scrollback data
by mistake. I can imagine that people might have been using it
precisely _to_ wipe the scrollback in some situations, but if so then
they should use CSI 3 J instead.

Two related changes to timing code:

First, make absolute times unsigned.  This means that it's safe to

integers).  This requires a little extra care in handling comparisons,

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.

Patch from Robert de Bath to substantially simplify timing.c.

The previous platform-dependent ifdefs, switching between a system
which tried to cope with spurious callbacks (which I'd observed on
Windows) and one which tried to cope with system clock jumps (which
can happen on Unix, if you use gettimeofday) have been completely
removed, and replaced with a much simpler approach which just copes
with system clock jumps by triggering any timers immediately.

None of the resulting effects should be catastrophic (the worst thing
might be the waste of CPU in a spurious rekey, but as long as the
system clock isn't jumping around _all_ the time that's hardly
critical) and in any case the Unix port has had a long-standing oddity
involving occasional lockups if pterm or PuTTY runs for too long,
which hopefully this should replace with a much less bad failure mode.
And the code is much simpler, which is not to be sneezed at.

New utility script to parse an SSH packet dump and write out an
interpretation with some analysis done on it. The script will do its
own tracking of the set of open channels and their states, and its
output is in a one-line-per-packet format such that every distinct
channel has a unique identifier in it which should make it easy to
grep out all lines relating to that channel. The script also matches
up {CHANNEL,REQUEST}_{SUCCESS,FAILURE} to the requests that caused
them, by tracking a queue of requests in each direction per channel
and for global requests. Command-line options permit generating a
final dump of all channels ever known to the script and their various
ids and final state, and also dumping out the data transferred over
each channel in each direction.

Output is not complete, in the sense that some parameters in some
messages (e.g. pixel sizes in window-size specifications) are
deliberately omitted due to being boring, and the entire contents of
some messages (e.g. KEXINIT) are omitted because I haven't yet seen
any purpose in decoding them. Filling them in might be a useful thing,
although I'm inclined to think that the default should still be to
show only the potentially interesting stuff (e.g. still not pixel
sizes!) and enable the rest using a -v option.

Hopefully this should do a lot of the legwork in debugging issues in
which a channel mysteriously remains partially open and prevents PuTTY
closing.
