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.

This also adds an omitted _decodedSampleCount initialization in Oki
ADPCM decoder.

This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'

Some backends may break as I only compiled SDL

- Split The Last Express' ADPCM to the engine. Using the MS IMA routine was really a hack.
- Fixed stereo MS IMA ADPCM, the old routine was completely wrong.

IMA is really just the definition on how to decode a sample from a nibble, DVI is just a way for those nibbles to be stored in the stream.

There are tons of ADPCM variants out there, and it is impractical to
stuff them all into a single adpcm.cpp file. By exposing the internals,
engines can implement their ADPCM decoder variants more easily.
