done properly (by binding to INADDR_LOOPBACK) instead of hackishly
(by binding to INADDR_ANY, looking at the peer address when a
connection is accepted, and slamming the connection shut at that
point).

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).

Only currently works on SSH1; SSH2 should be doable but it's late
and I have other things to do tonight. The Cool Guy award for this
one goes to Nicolas Barry, for doing most of the work and actually
understanding the code he was adding to.

version allows you to specify, per socket, which sockets receive OOB
data in-line (so that you know what was before the mark and what was
after) and which receive it out of line (so it's really a one-byte
out-of-band facility rather than discard-to-mark). This reflects the
fact that rlogin appears to make more sense in the latter mode, and
telnet in the former. This patch makes rlogin work right for me.

automatic fatalbox(). Instead, the error is passed to the receiver
routine, which can decide just how fatal the problem really is.

smalloc() macros and thence to the safemalloc() functions in misc.c.
This should allow me to plug in a debugging allocator and track
memory leaks and segfaults and things.

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.
