[Freeciv-Dev] 1/2 readline patch

[Thue Janus Kristensen <thue@xxxxxxx>]

I have tried making readline work with the civserver, but haven't been
completely succesfull.
-When suspending the server (CTRL-z) the server would for some reason
think it had gotten a new client connection and get stuck in the client
accept function.
-when you are typing some text and a line of output appears (fx telling
you the game have been autosaved) the prompt will not reappear by itself
-I did not code any autocompletion functionality.

If anybody want to give it a try then go ahead. It is mostly the first
problem that has me stuck.
