Refactored the ProLogicII code into a separate file and changed it to floating point math for easier debugging.
Added a basic ProLogic decoder that doesn't try to do surround separation into L/R.
The setting does not have a GUI option yet, since the PLII decoder is experimental and doesn't give too good results.
To change it, set DplDecodingLevel to one of: 0=none, 1=ProLogic, 2=ProLogicII. The default is 0.

Causes internal buffer size allocations to be as small as possible within portaudio and the OS, so it can have bad effects if the number turns out to be too small.
Would be nice if someone with a "real" audio card (Audigy, X-fi or similar) tested WASAPI Exclusive Mode, KS or ASIO with this change.

On 4840 I added dynamic tuning (which may have slight negative effect on stability) to adapt to different iterations/sec of different systems, but I didn't like this system too much. On 4840 I also made a small change which, I now understand, factors out the differences between systems in this regard, essentially making dynamic tuning not required anymore. So now dynamic tuning is disabled.
If you enable the SPU2X messages (and the overrun messages), you would see log messages similar to this:
buffers: 44 ms ( 89%), tempo: 1.000000, comp: 1.000, iters: 764, (N-IPS:750 -> avg:50, minokc:50, div:100)
If the iters value (764 at this example) on your system when running at 100% speed (50/60fps) is higher than 1000 or lower than 500, then please comment here and post few of the log lines.

I'm not fully happy with it, as it's a bit complicated for my taste, so feedback about how it performs will be appreciated.

1. Much better behavior at extreme low/high FPS (less skips/lower latency).
2. As a result, I was able to reduce internal latency by 50% (50ms config now equals 100ms before).
Recommended latency config for stretcher: 100ms.
For rhythm games, if your FPS is very stable, I recommend 50ms.

Pcsx2 now has a gifUnit class which acts like the ps2's gif and executes a single gif transfer at a time (and performs path arbitration according to priority and path3 slicing).
This new code is generally a speedup for most games. Particularly VU heavy games like GoW.
This revision breaks old saved state compatibility so don't update if you wish to keep playing with your old saved states.
Leave comments if this revision fixes or breaks anything...
Message to GS Plugin authors:
This new code now uses only 1 gif callback to transfer data to the gs plugin (GSgifTransfer).
pcsx2 also is garaunteed to send full GS primitives to the plugin. So you don't have to account for partial-transfers anymore.
Thanks goes out to shadowlady who tested around 500 games for me :D
Note 1: The old gif code is still in this revision, and can be enabled by the USE_OLD_GIF macro. The old code will be deleted soon.
Note 2: This revision also enables assertion dialogs in devel builds, and changed a lot of assume cases into assertions.

Should prevent erratic tempo variations near 100% speeds (compared to the previous implementation), and generally allow much lower latencies while keeping the audio stable (on all audio systems).
E.g. my tests show that at 70ms latency it can properly handle sharp speed variance of 50%-100%. If your game generally doesn't get slower than 70% speed, 50ms latency would probably be fine.
Note that on extreme scenarios (e.g. extreme sharp drops in speed) it doesn't try to keep the audio continues at all costs. If your game exhibits such behavior (audible clicks, etc), increasing the latency a bit at the config would help.
Comments on actual performance/quality on different systems would be greatly appreciated.

Before trying this revision, make sure your speakers/headphones are not too loud.
I have been looking at it for a long while, and I decided it couldn't be just "somewhat similar" to a Schroeder Reverberator.
The SPU2 designers would have actually used a working design for a reverberator, so chances are they implemented Schroeder's.
I haven't had the chance to test this code in spu2-x, but the results in the "Impulse Response Analyzer" tool I coded specifically for this, are positive.
Some tweaks might be needed, because I'm not sure if Neill got the IIR part right or not.

Some work on the fake reverb. Renamed it to "Custom Reverb" and the original to "SPU2 Reverb".

- Replaced the reverb boost control with a selector for normal reverb or a new mode we call "fake reverb".
- This new mode (coded by gigaherz) is intended as an alternative for the only partially working "normal reverb".
- The new mode will have to be tuned yet to sound good.
