callbackOutput() and updateCallback3() functions won't change the channel data
pointer unless the new sound has a higher unk2 and the current one.
Since it's set to 0 when the data pointer is nulled, I've changed the priority
to be unsigned.
The updateCallback22() function is now update_setPriority().

level", which I believe is the individual channel volume. (The functions also
return the "scaling level" bits, but they are preserved, not calculated.) I
have renamed these functions calculateOpLevel1() and 2().
The unk25 and unk26 variables have been renamed opLevel1 and opLevel2. These
are called oplvl_1 and oplvl_2 in our MidiDriver_ADLIB class.
The unk26, unk27 and unk28 variables are potentially added to both operator
levels, and have been renamed opExtraLevel1, opExtralevel2 and opExtraLevel3.
The updateCallback25() function has been remamed update_setExtraLevel1().
The updateCallback33() function has been renamed update_setExtraLevel2().
The updateCallback32() function has been renamed update_setExtraLevel3().
Note that these callbacks aren't quite as similar as their names would seem to
indicate: They differ in whether or not the volume is updated and/or how the
parameters are passed.

stuff, it pretty much has to be our "set instrument" function. Also, while I'm
not entirely sure of the implications, "unk23" is the Algorithm bit for the
Feedback / Algorithm register, so I've renamed it "algorithm".

- Adds sound fading support to the adlib player
- Adds support for stopping running tracks
- Changes baseFreq type back to uint8
- corrects octave handling in updateAndOutput1
(Thanks to eriktorbjorn for doing that)

all: it adjusts the frequency even when state.unk16 is zero. Fixed that, and
added some comments to hopefully explain the differences between the cleaned up
code and the original disassembly.

* Rewrote updateCallback41() in terms of updateAndOutput1(), since they were
almost identical to begin with.
* Rewrote updateAndOutput1() for better readability.
* Made unk10 signed, and renamed it baseOctave.
* Made unk14 signed, and renamed it baseNote.
* Made unk15 signed, and renamed it baseFreq.
* Renamed unk17 regAx. It appears to be a cache for that register.
* Renamed unkOutputValue1 regBx. It appears to be a cache for that register.
* Renamed updateCallback8() update_setBaseOctave().
* Renamed updateCallback13() update_setBaseNote().
* Renamed updateCallback20() update_setBaseFreq().
Which still leaves the mystery of unk16 and _unkTables[]. Perhaps *this* is the
pitch bend?

_unkTable[]. Investigating the latter further might help unravelling several of
the "unk" variables. (Right now, I'm suspecting that unk15 is the pitch bend.)

the octave bits.
The unkOuput1() function always turns off the note, so I've renamed it
noteOff(). I've added some comments to unkOuput2() as well, but I'm still not
quite sure what its purpose is. It seems unlikely that it's simply a "note on"
function, given the many things it will clear for the channel. It does end by
turning the note on, though. Strange.

game descriptions. Doing this now is the responsibility of the engines.
- Adapted the SCUMM engine to add lang/platform to the desc string if
necessary. Other engines still have to be adapted (but many do not seem to
need this at all, since they either are lang/platform agnostic, or already
include this information in their MD5 tables).
