mid-session in SSH2: this forces an immediate rekey to activate the
new settings. I'm not sure exactly what this will be useful for
(except possibly it might make comparative performance testing
easier?), but it has wonderful James Bond value for being able to
switch to a more secure cipher before doing anything sensitive :-)
If, that is, you weren't using the most secure one to begin with...

of polishing to bring them to what I think should in principle be
release quality. Unlike the unfix.org patches themselves, this
checkin enables IPv6 by default; if you want to leave it out, you
have to build with COMPAT=-DNO_IPV6.
I have tested that this compiles on Visual C 7 (so the nightlies
_should_ acquire IPv6 support without missing a beat), but since I
don't have IPv6 set up myself I haven't actually tested that it
_works_. It still seems to make correct IPv4 connections, but that's
all I've been able to verify for myself. Further testing is needed.

of directory recursion was a strategic error: it obfuscates
sftp_{get,put}_file(), and also it makes it very hard to handle
subdirectory wildcards such as `foo/*'. Accordingly, here's a
completely different approach, in which sftp_{get,put}_file() are
still responsible for directory recursion, but wildcards are
expanded in sftp_general_{get,put}() before being passed thereto.
Subdirectory wildcards are now handled consistently across Unix,
Windows and the remote server.

mid-session if we are not using SSHv1. I've done this by introducing
a generic `cfg_info' function which every back end can use to
communicate an int's worth of data to setup_config_box; in SSH
that's the protocol version in use, and in everything else it's
currently zero.

bit is working out when to reschedule the next rekey for when the
timeout or data limit changes; sometimes it will be _right now_
because we're already over the new limit.
Still to do: the Kex panel should not appear in mid-session if we

Change Settings, the port forwarding setup function is run again,
and tags all existing port forwardings as `do not keep'. Then it
iterates through the config in the normal way; when it encounters a
port forwarding which is already in the tree, it tags it `keep'
rather than setting it up from scratch. Finally, it goes through the
tree and removes any that haven't been labelled `keep'. Hence,
editing the list of forwardings in Change Settings has the effect of
cancelling any forwardings you remove, and adding any new ones.
The SSH panel now appears in the reconfig box, and is empty apart
from a message explaining that it has to be there for subpanels of
it to exist. Better wording for this message would be welcome.

routine which is common between SSH1 and SSH2. Since this routine is
not part of the coroutine system, this means it can't sit and wait
to get its various success/failure responses back. Hence, I've
introduced a system of queued packet handlers, each of which waits
for exactly one of a pair of messages (SSH1_SMSG_{SUCCESS,FAILURE}
or SSH2_MSG_REQUEST_{SUCCESS,FAILURE}), handles it when it arrives,
and automatically de-registers itself. Hence the port-forwarding
setup code can be called once, and then subsequent packets related
to it will automatically be handled as they arrive.
The real purpose of all this is that the infrastructure is now there
for me to arrange mid-session configurability of port forwarding.
However, a side benefit is that fewer round trips are involved in
session startup. I'd quite like to move more of the connection setup
(X forwarding, agent forwarding, pty allocation etc) to using the
new queued handler mechanism for this reason.

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,

to call _either_ do_text() _or_ do_cursor() on a given character
cell. In fact you're supposed to call do_text() no matter what, and
then call do_cursor() as well if it's got the cursor on it, since
do_cursor() _only_ draws the actual cursor, which often doesn't also
cause the text to get drawn.
I'm half tempted to change this in the interface, retire do_cursor()
as an external function and relegate it to an internal function in
each front end, and require that do_text() must fully process all
cursor attributes it is passed. However, I haven't done this yet.

incorrect. I must have written that binary search idiom a hundred
times, so it's rather embarrassing that I can't _automatically_ get
it right! This was causing all kinds of characters to be classified
as ON when they should have been various other classes.
Also while I'm here, I've added another test case to utf8.txt (a
small piece of Arabic within a predominantly L->R line), and also
supplied a means to compile minibidi.c with -DTEST_GETTYPE to
produce a command-line character class lookup tool. (Not sure what
use that'll be _other_ than debugging this precise problem, but I
don't like to throw it away now I've written it :-)

the start of every contiguous run passed to do_text() or
do_cursor(), and arranges never to overwrite only part of such a run
on the next update.
I'm a bit worried about this checkin because I've also completely
revamped cursor handling: the cursor was previously being drawn
_outside_ the main loop over the display line, and is now drawn as
part of that loop when it gets to the cursor location. It _seems_ to
still work sensibly, even in complex cases involving LATTR_WIDE and
double-width CJK characters etc, but I won't be entirely happy until
it's had some beta use.

going through the line and working out which bits need to be redrawn
is now in a separate loop from the subsequent activity of actually
going through and doing the redraws. This _should_ enable me to
tinker with the which-bits-to-redraw data in between the two, thus
fixing `font-overflow'. However, I thought it would be sensible to
break the work up into two commits so we can track bugs in the
restructuring separately from bugs introduced by the new feature.
Also added a couple more terminal test files.
