Created a shiny new abstraction for the socket handling. Has many
...
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.

Introduce a sane interface function, from_backend(), for backends to
...
use when they have data from the network. Replaces the utterly daft
inbuf / inbuf_head / term_out() interface, which only made sense
when feeding to terminal.c. (terminal.c now implements
from_backend() as a small function that gateways to the old
interface.)
As a side effect, from_backend() also has an `is_stderr' parameter,
so scp can once again separate the server's pronouncements on stderr
from the actual protocol progress on stdout.

PuTTYgen initial version. Still to do are basic user-friendliness
...
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.

- define yet more terminal compatibility modes
