In idSampleDecoderLocal::DecodeOGG() `totalSamples` was 1 and
`reqSamples` was 0, which caused an endless loop.. this was caused by
idSoundWorldLocal::ReadFromSaveGame() setting
`chan->openalStreamingOffset` to an odd number, I think due to
`currentSoundTime` being an odd number.
To fix that, I round up `chan->openalStreamingOffset` to a (very) even
number, and to be double-sure I also added a check in DecodeOgg() to
make sure it exits the loop if `reqSamples` is 0.
In idSampleDecoderLocal::DecodeOGG() sometimes (esp. in The Lost Mission
mod) it happens that stb_vorbis_get_samples_float() decodes one sample
less than expected so one is left and when trying to decode that,
stb_vorbis_get_samples_float() returns 0, which we interpreted as an error.
This case is now handled more gracefully: No warning is printed (except
if developer 1) and failed is not set (setting it would prevent the sound
from being played again, I think).
Seems to work; note that idWaveFile is only ever used in idSoundSample::Load()
As stb_vorbis doesn't support custom callbacks for reading, I feed it
the full .ogg files as a buffer. Shouldn't make much of a difference
though - either the whole file is decoded on load anyway (so the buffer
is freed after decoding, or it's streamed, but in that case the old code
also kept the whole ogg file in memory by using idFily_Memory.
I also added warning messages in places where calls to stb_vorbis_*()
can fail, where there were none in the equivalent libvorbis code.
Don't include the lazy precompiled.h everywhere, only what's
required for the compilation unit.
platform.h needs to be included instead to provide all essential
defines and types.
All includes use the relative path to the neo or the game
specific root.
Move all idlib related includes from idlib/Lib.h to precompiled.h.
precompiled.h still exists for the MFC stuff in tools/.
Add some missing header guards.
