Factor out some common code in {ux,win}cons.c. The assorted host-key and warning prompt messages have no reason to differ between the two platforms, so let's centralise them. Also, while I'm here, some basic support functions that are the same in both modules.

/*
* Common pieces between the platform console frontend modules.

Mention the host name in host-key prompts. Now that it's possible for a single invocation of PuTTY to connect to multiple SSH servers (jump host followed by ultimate destination host), it's rather unhelpful for host key prompts to just say "the server". To check an unknown host key, users will need to know _which_ host it's purporting to be the key for. Another possibility is to put a message in the terminal window indicating which server we're currently in the SSH setup phase for. That will certainly be what we have to end up doing for userpass prompts that appear _in_ the terminal window. But that by itself is still unhelpful for host key prompts in a separate dialog, because the user would have to check both windows to get all the information they need. Easier if the host key dialog itself tells you everything you need to know to answer the question: is _this_ key the one you expect for _that_ host?

Centralise host key message formatting. The format _strings_ were previously centralised into the platform- independent console.c, as const char arrays. Now the actual formatting operation is centralised as well, by means of console.c providing a function that takes all the necessary parameters and returns a formatted piece of text for the console. Mostly this is so that I can add extra parameters to the message with some confidence: changing a format string in one file and two fprintf statements in other files to match seems like the kind of situation you wish you hadn't got into in the first place :-)
