gatserver: Refactor IO code

The current GAtServer implementation had nasty corner cases where
multiple commands were issued on the same command line.  The
server_suspend had no effect and we ended up processing the second
command anyway, resulting in interesting side-effects or crashes.

This commit simply discards the rest of the read input if the server
starts processing a command.  Since we do not yet support command
abortion we also discard data that arrives when command is being
processed.
