This update uses upstream commit
f88ef828a600ce66d1f730c8fb2a7f580f6f6165.
This update switches to use the new Munt C++ interface, which
will allow ScummVM to link to an external Munt library instead
of requiring it to be built-in in the future. For the moment,
the emulator is still built-in, since it is not available from
most package repositories.
The Munt driver in ScummVM now uses writeSysex instead of the
(now-private) playSysexWithoutFraming, per recommendation from
the Munt team <https://github.com/munt/munt/pull/30>.
This changeset also removes direct modifications that used to be
made to Munt code, to ease future updates. To update Munt code in
the future:
1. Replace all source files in the `softsynth/mt32` directory with
new files from the upstream `mt32emu/src` directory;
2. Update `config.h` with the correct version number for the new
version of Munt;
3. Update `module.mk` to add any new source files that need to be
built.

This fixes the audio in the intro AVI movie for German Fullpipe.

The CMS emulation assumes the chips run at 8 MHz clock,
but in PCs they run at 7.15909 MHz, so the emulated pitch
is too high. Adjusting the requested sampling rate higher
by matching amount the pitch is lowered down to normal.

Since _decodedSamples[] is filled with either 2 or 4 samples, we
can't use 1 - (count - 1) to "ensure that acts as a FIFO". When
we have 4 samples, that index will become negative, putting
uninitialized data into the buffer.
We could still use a similar trick, but I think it's much clearer
to use an index variable like this. We need an addition variable
either way.

This allows raw PCM in WAVE containers to have duration and be
seekable, and opens the door for ADPCM streams to be seekable later
if necessary.
This change is needed to avoid duplication of RIFF/WAVE container
parsing for SCI engine, which uses raw PCM WAVE files and needs to
be able to determine their lengths.

Since it was --voice, we were reading element index -1.

This fixes the Indiana Jones and the Fate of Atlantis specific issue reported
in bug #6242 "AUDIO: Built-In MT-32 MUNT Produces Wrong Sounds".
Delaying MIDI events has been introduced with Munt 1.3.0.
Regression from 00992c1e68444a8123ffc89a971751cecf7287ed.

Since we are not using munt's SHA-1 hashing code, this returns the most
appropriate feature set for CM-32L ROMs
|
|
This reverts commit 908d2f39d7579c3f1781f7dedc7b26366a6d3dfc.
The licence of the SHA1 code that munt is using is unclear.
Reverting until it's sorted properly, for now

This ensures that the CM32-L ROMs will be preferred, if both sets are
located in the same folder
|
|
This ensures that the capabilities of the detected ROM files are
set properly from the list of known ROMs. This is mostly needed
for the extra samples of the CM32-L ROMs

(This works around issues with some Indy 3 sound tracks. These tracks seem to be broken, since they have way too long duration values for some notes which would fill up the event buffer rather quickly. I tested with the UNZ emulator to be sure that this is an issue which also occurs with the original driver.)
