scummvm/sword2/events.cpp
Torbjörn Andersson c0a3816e17 Began what I hope is the final major restructuring of the BS2 engine.
In this first step, I have moved all opcode functions into functions.cpp,
instead of having them scattered all over the place.

To get things to compile again, I had to rewrite the overly complicated
sound effects handling. It's much simpler now.

The next step will be to move any non-trivial code out of the opcode
functions and into the appropriate object. This, I hope, will make it
easier to create well-separated objects, instead of the current mess.

I also want to tear down the artificial boundary between the main directory
and the "driver" directory. We already have a cross-platform layer; there's
no need to have yet another one. (Actually, the rewriting of the sound
effects code took one first step in this direction.)

At the final stage, I'd like to get rid of the "drivers" directory
completely, but I'll probably need some help with that if I want to
preserve the CVS history of the code.

Things will probably be a bit bumpy along the way, but I seem to have
reached a point of relative stability again, which is why I'm commiting
this now.
