969ef3dac9 * Added new virtual base class 'Stream', ReadStream and
WriteStream are now subclasses of it.
* Added new methods eos(), ioFailed(), clearIOFailed() to
  all streams. This allows better error checking.
* SaveFile classes take advantage of these new standard
  stream APIS
* Removed File::gets()
* Added SeekableReadStream::readLine() (replaces File::gets)
* Added WriteStream::writeString, for convenience

a5356edb36 Got rid of all the .h files but one in the 'driver' directory. They were
either very small or, in the case of driver96.h, a disorganized jumbles.

807b33ec29 More BS2 restructuring.
The various game settings are no longer stored in the Gui class. They are
stored in the class that use them.

Code that doesn't belong in the Gui class, e.g. the "restart" code, has
been moved out of it.

Afterwards, the Gui class had been reduced to nothing more than a handful
of trivial methods for invoking the in-game dialogs. So the entire Gui
class has been removed.

43cfe01f3d This is the second part of the BS2 restructuring. There are two new
classes: Screen and Mouse. Screen handles most of the drawing, except the
mouse cursor and in-game menus.

The old Graphics class is no more.

I've also fixed some "reverse stereo" regressions from the first part of
the restructuring.

I'm not sure what the next step will be, but hopefully it will be smaller
than this one was.

fe3e01a110 Now there are two file handles for the music: one for each CD. This is not
the same thing as one for each music stream. If both music streams are
playing music from the same CD, they will both take turns at using the same
file handle.

The only case where both file handles are used is when music from one CD is
fading in while music from the other CD is fading out. Which of course can
only happen if you play the game from hard disk. If the game has to ask for
the other CD, it kills the music immediately.

The reason for doing this is that there was some concern about whether
having two file handles open to the same file was portable or not. I don't
think that question was ever fully answered, so I avoid the situation.

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.

ca58bfed3b Fixed bug that I must have introduced during one of my cleanups. The
original code read "LLogic.Logic_up( (*params*65536)+2);".

I don't know where this opcode is actually used, though.

f04e412269 Rewrote the code that loads credits.clu into memory. The new code is
perhaps less clever than the old one I wrote, but should be much easier to
read. Besides, the old code had a small memory leak in it.

cb399b63d5 Added support for compressed music. I'm sure there are some glitches still
to fix, but it should work well enough for now.

In this rewrite of the music code, I removed the "save/restore music state"
function, since it just complicated things for a very small gain. It wasn't
in the original engine, and I added it just for the credits, so that the
previously playing music could be resumed afterwards. I might re-add it
later, but probably not.

3c70f5a85c If the 'time' parameter to displayMsg() is 0, wait until the user clicks
or presses a button. This is how displayMsg() was always used, so the only
difference is that the code to check for events is no longer outside the
function.

In the process, it turned out that removeMsg() was probably unnecessary so
I have removed it. May cause regressions, but we can deal with them later.

0426d38aa5 Cleaned up the palette handling a bit. Renamed _palCopy to _palette since I
found the old name misleading (there is only one array that stores the
palette in the engine, though it could be argued that it's a copy of the
one used by the backend), and removed some code that I'm almost certain was
never used. (I've added assert()s to trigger in the cases where it would
have been used.)

fc970b3c75 Removed the buffering of mouse and keyboard events. I don't think any of
our other engines do this, so there is little reason for BS2 to. I did add
a filtering mechanism so that mouse button releases and scroll wheeling is
ignored during normal gameplay, but I don't know if that was necessary
either.

Since this left little more than an empty husk where the Input class used
to be, I've eliminated that class and buried its remains in Sword2Engine.

4c3a68027f Use the same syntax for accessing script variables as BS1 does, i.e. now
it's Logic::_scriptVars[ID] instead of just ID. Apart from looking cool, it
makes it much easier to tell the difference between variables and constants
when looking at the code.

Of course, this sort of sweeping changes is jolly good for introducing
truly weird regressions, which is why I waited until after 0.6.0.

8a91ae3257 Adapted LavosSpawn's idea for more efficient screen updating. It still
renders the entire screen every frame, but it tries to update (i.e. copy to
the backend) only the parts of the screen that actually changed. At least
approximately so.

3d012651fd The script engine frequently needs to pass pointers to various structures
etc. to the different opcodes. Until now it has done so by casting the
pointer to an int32 (opcode parameters are represented as arrays of int32)
and then the opcode function casts it back to whatever pointer it needs.

At least in C there is no guarantee that a pointer can be represented as an
integer type (though apparently C99 may define such a type), so this has
struck me as unsafe ever since I first noticed it.

However, since all such pointers appear to point to the memory block owned
by the memory manager, we can easily convert them to integers by treating
them as offsets into the memory block. So that's what I have done. I hope I
caught all the occurences in the opcode functions, or we're going to have
some pretty interesting regressions on our hands...

688c80b062 Moved more stuff into classes, changed some static allocation to dynamic,
and removed some of the references to global variables.

At this point I believe everything in the main game engine has been moved
into classes - not necessarily the correct ones, but still... However,
there is some stuff in the driver directory that need to be taken care of
as well.

their names to open() and close(), but I've changed my mind now.)
