Implement FAPOFX

[flibitijibibo]

I just finished stubbing in the four effects provided by XAPOFX:

12a918b

This will improve compatibility with games that depend on it, but note that I have NOT implemented the XAPOFX DLLs. I've found that the X3DAudio DLL has given us more than enough trouble to warrant putting that off deliberately until we have something that can actively go out for use in something like Proton, so for this we'll do that after everything else is written.

Here's the checklist:

• Write testfx program, similar to testreverb
• FXEQ
• FXMasteringLimiter
• FXReverb - Maybe rip off FAudioFXReverb?
• FXEcho
• Wrapper DLL Project Files

Here's the MSDN documentation for XAPOFX.

If you need the CLSIDs for XAPOFX, you can find them here (sorry Johan!):

Heya, just wanted to add on to this, these DLLs are needed for quite a few games including some that have already been whitelisted by steam (Wolfenstein: TNO/TOB). I went to test the WMA PR in warframe, and came across it wanting xapofx1_5. I then removed the xapofx dlls from being set as native, and came across this:

3.652 Sys [Info]: S0009:err:ole:COMPOBJ_DllList_Add couldn't load in-process dll L"C:\\windows\\system32\\xaudio2_7.dll"
p0009:err:ole:CoGetClassObject no class object {5a508685-a254-4fba-9b82-9a24b00306af} could be created for context 0x1

which upon further searching, lead me to this old bug report which had been fixed by a stub:

https://bugs.winehq.org/show_bug.cgi?id=26808

obviously you know a "lot of games" need these, not trying to beat a dead horse. I'm just mentioning in particular because some of those games are whitelisted on steam play.

Much like X3DAudio I’m recommending the DXSDK version of XAPOFX for now - they should be compatible with FAudio and its COM wrapper. Implement the effects first, then we can talk about the DLL.

As of this commit the DLL should be a one-line function:

Still not making it until the rest is finished but it helps make the last step really quick.

While looking at the Wine built-in path again I ended up implementing the source, which should work as a native DLL. No project files though, so this is solely to fix up the built-ins:

Ended up adding XAPOFX for Warframe as well...

So it's just the Visual Studio projects that's left. Thankfully nobody but me and XNA4 people have VS2010 anymore, so surely this won't get done before the actual code...?!
