fix build on plan 9 (lots of changes)

About

This is a improved version of `games/glendy`, also known as trap the cat game.

the goal of the game is to either escape the trapper,
or manage to block the bunny (also known as glenda);

two clients currently are included, plan 9 client and cli client.
new features:
	- ablity to play as glenda
	- multiplayer (local and networked)
	- better colors!
	- cli and sdl clients
	- game server

game logic is seprated from client details and interface,
and can be found on engine.[ch], there are also some portablity code
in `unix.c`.

`cli.c` and `gui9.c` contain clients, there is also a server in `srv.c` (also `srv4.c`, `srv5.c`),
cli client current doesn't support networked mode, because i'm too lazy
to implement networking in a portable manner between UNIX and plan 9.

there are some documention of engine details and networked protocol in doc.
