Changelog:
- ruby: rewrote the API interfaces for Video, Audio, Input
- ruby/audio: can now select the number of output channels (not useful
to higan, sorry)
- ruby/asio: various improvements
- tomoko: audio settings panel can now select separate audio devices
(for ASIO, OSS so far)
- tomoko: audio settings panel frequency and latency lists are
dynamically populated now
Note: due to the ruby API rewrite, most drivers will not compile. Right
now, the following work:
- video: Direct3D, XShm
- audio: ASIO, OSS
- input: Windows, SDL, Xlib
It takes a really long time to rewrite these (six hours to do the
above), so it's going to be a while before we're back at 100%
functionality again.
Errata:
- ASIO needs device(), setDevice()
- need to call setDevice() at program startup to populate
frequency/latency settings properly
- changing the device and/or frequency needs to update the emulator
resampler rates
The really hard part is going to be the last one: the only way to change
the emulator frequency is to flush all the audio streams and then
recompute all the coefficients for the resamplers. If this is called
during emulation, all audio streams will be erased and thus no sound
will be output. I'll most likely be forced to simply ignore
device/frequency changes until the user loads another game. It is at
least possible to toggle the latency dynamically.

Note: for Windows users, please go to nall/intrinsics.hpp line 60 and
correct the typo from "DISPLAY_WINDOW" to "DISPLAY_WINDOWS" before
compiling, otherwise things won't work at all.
This will be a really major WIP for the core SNES emulation, so please
test as thoroughly as possible.
I rewrote the 65816 CPU core's dispatcher from a jump table to a switch
table. This was so that I could pass class variables as parameters to
opcodes without crazy theatrics.
With that, I killed the regs.r[N] stuff, the flag_t operator|=, &=, ^=
stuff, and all of the template versions of opcodes.
I also removed some stupid pointless flag tests in xcn and pflag that
would always be true.
I sure hope that AWJ is happy with this; because this change was so that
my flag assignments and branch tests won't need to build regs.P into
a full 8-bit variable anymore.
It does of course incur a slight performance hit when you pass in
variables by-value to functions, but it should help with binary size
(and thus cache) by reducing a lot of extra functions. (I know I could
have used template parameters for some things even with a switch table,
but chose not to for the aforementioned reasons.)
Overall, it's about a ~1% speedup from the previous build. The CPU core
instructions were never a bottleneck, but I did want to fix the P flag
building stuff because that really was a dumb mistake v_v'

This WIP substantially restructures the ruby API for the first time
since that project started.
It is my hope that with this restructuring, destruction of the ruby
objects should now be deterministic, which should fix the crashing on
closing the emulator on Linux. We'll see I guess ... either way, it
removed two layers of wrappers from ruby, so it's a pretty nice code
cleanup.
It won't compile on Windows due to a few issues I didn't see until
uploading the WIP, too lazy to upload another. But I fixed all the
compilation issues locally, so it'll work on Windows again with the next
WIP (unless I break something else.)
(Kind of annoying that Linux defines glActiveTexture but Windows
doesn't.)

Finally!! Compilation works once again on Windows.
However, it's pretty buggy. Modality isn't really working right, you can
still poke at other windows, but when you select ListView items, they
redraw as empty boxes (need to process WM_DRAWITEM before checking
modality.)
The program crashes when you close it (probably a ruby driver's term()
function, that's what it usually is.)
The Layout::setEnabled(false) call isn't working right, so you get that
annoying chiming sound and cursor movement when mapping keyboard keys to
game inputs.
The column sizing seems off a bit on first display for the Hotkeys tab.
And probably lots more.

Not an official WIP (a WIP WIP? A meta-WIP?), just throwing in the new
fullscreen code, and I noticed that OpenGL colors in 30-bit mode are all
fucked up now for some strange reason. So I'm just using this snapshot
to debug the issue.
