RFC: OpenAL Winmm driver and OpenAL32.dll thunk -- 2

[Nick Burns]

(due to alut changes -- im asking for comments again -- if no problems -- 
ill try and submit)
------

Very cool audio worked for you as well...
I too noticed the stereo effects in ut2004 and was taken aback -- first it 
was like -- its only on the right -- the the sound zipped over (never heard 
it like that before) good thing i had my airsick-bag handy.

--
Ok those build failures are not totally unexpected -- depending on yer impl 
of openal -- they may have broken binary compat (i would 'nm' (list exported 
symbols of) your openal lib) and look for alut*.
Very surprising that those functions are missing thou -- they are supposed 
to be there...

freealut will fix the binary compat issues -- so its not the biggest problem 
-- what i could do is be safer with alut and have the configure test for 
each alut function that SHOULD be in the openal lib.

OR better yet I can just IMPL the lame (OLD DEPRECATED) alut functions on 
top of openal inside openal32.dll -- this is probably the most portable and 
best solution...
(I would just copy the impl from freealut) Looking at freealut... It is 
doable -- but it quite a bit of extra code...

OR I can drop alut support altogether

so the possibilities...
1 - require freealut
2 - impl alut functions on openal (using freealut code 5 functions -> 7 
files)
3 - stub alut -- then use freealut to impl these (never used dead 
deprecated) functions
4 - remove alut

I have choosen 3 -- attaching my patch with those changes in (and removed 
some meaningless comments)

These stubs will FIXME -- if hit.

The stubbing is controlled with 'USE_BUILTIN_ALUT' in openal.c

---
btw if you dont have openal it will still build -- but spew at you if it is 
used -- that openal is not supported...
