Rather than the top-level component of X forwarding being an
X11Display structure which owns some auth data, it's now a collection
of X11FakeAuth structures, each of which owns a display. The idea is
that when we receive an X connection, we wait to see which of our
available auth cookies it matches, and then connect to whatever X
display that auth cookie identifies. At present the tree will only
have one thing in it; this is all groundwork for later changes.

zero but does it in such a way that over-clever compilers hopefully
won't helpfully optimise the call away if you do it just before
freeing something or letting it go out of scope. Use this for
(hopefully) every memset whose job is to destroy sensitive data that
might otherwise be left lying around in the process's memory.

modes of operation all took separate source and destination pointers. They
were never called with those pointers different, though, so reduce them to
a single pointer like everything else uses.

- We were using the first word of each block of keystream block twice and the
second not at all.
- We were incrementing the high-order word of the counter after every block
rather than the low-order one.
With those fixed, our 3des-ctr implementation interoperates with the one in
Moussh. Thanks to der Mouse for his help with the testing.
3des-ctr is now enabled by default.

default preferred cipher), add code to inject SSH_MSG_IGNOREs to randomise
the IV when using CBC-mode ciphers. Each cipher has a flag to indicate
whether it needs this workaround, and the SSH packet output maze has gained
some extra complexity to implement it.

aes128-ctr, aes192-ctr, and aes256-ctr. blowfish-ctr and 3des-ctr are
present but disabled, since I haven't tested them yet.
In addition, change the user-visible names of ciphers (as displayed in the
Event Log) to include the mode name and, in Blowfish's case, the key size.

discussed. Use Barrett and Silverman's convention of "SSH-1" for SSH protocol
version 1 and "SSH-2" for protocol 2 ("SSH1"/"SSH2" refer to ssh.com
implementations in this scheme). <http://www.snailbook.com/terms.html>

seems to be entirely the same as "des-cbc", so supporting it is trivial
and we may as well do so. If nothing else, it makes it clear whose fault
it is.

malloc functions, which automatically cast to the same type they're
allocating the size of. Should prevent any future errors involving
mallocing the size of the wrong structure type, and will also make
life easier if we ever need to turn the PuTTY core code from real C
into C++-friendly C. I haven't touched the Mac frontend in this
checkin because I couldn't compile or test it.

the remote IP/port data provided by the server for forwarded
connections. Disabled by default, since it's incompatible with SSH2,
probably incompatible with some X clients, and tickles a bug in
at least one version of OpenSSH.

we're going to be a security program, we can at least make a token
effort to use the most secure local X auth available! And I'm still
half-tempted to see if I can support it for remote X servers too...

source files in which it's no longer required (it was previously
required in anything that included <putty.h>, but not any more).
Also moved a couple of stray bits of exposed WinSock back into
winnet.c (getservbyname from ssh.c and AF_INET from proxy.c).

error messages are currently wrong, and Pageant doesn't yet support
the new key type, and I haven't thoroughly tested that falling back
to password authentication and trying invalid keys etc all work. But
what I have here has successfully performed a public key
authentication, so it's working to at least some extent.

introduce another layer of abstraction in SSH2 ciphers, such that a
single `logical cipher' (as desired by a user) can equate to more
than one `physical cipher'. This is because AES comes in several key
lengths (PuTTY will pick the highest supported by the remote end)
and several different SSH2-protocol-level names (aes*-cbc,
rijndael*-cbc, and an unofficial one rijndael-cbc@lysator.liu.se).

features (prompt for passphrase twice, prompt before overwriting a
file, check the key file was actually saved OK), testing of the
generated keys to make sure I got the file format right, and support
for a variable key size. I think what's already here is basically
sound though.
