fteqw/engine/server/sv_demo.c
Spoike 503eff6421 Reworked the filesystem. We now support a virtual filesystem. Many places accept stream usage, although many formats do not support this.
I'm not sure if this will break anything. It shouldn't do, but it might.

Not everything is ported over yet. Ideally there would be no more use of fopen anywhere else in the engine, and com_gamedir would be made static to fs.c
There are a couple of other changes too.

http/ftp stuff is currently disabled.
