This prevents Timidity++ from playing externally, so it now always goes through
the sound system. Aside from the issues relating to controlling playback, that
functionality has been busted for who knows how long anyway since Open() always
tries to create a pipe and sound stream regardless of the calculated size.
Rather than building a command line that's going to be manually split into
individual arguments passed to execvp, build the individual arguments directly.
For non-Windows systems, read() may be non-blocking and can return less than
the requested amount if the timidity process hasn't written enough audio yet.

Add code to find the timidity executable, and split the command line into separate arguments by spaces.
For some reason, this doesn't work, although reverting 64e96c5f makes timidity work again.
This helps to avoid flooding of output with the following messages on every MIDI song change:
fluidsynth: error: Unable to open file "/usr/share/sounds/sf2/FluidR3_GS.sf2"
fluidsynth: error: Couldn't load soundfont file

Use snd_streambuffersize CVAR to set buffer size in kilobytes, from 16 to 1024
Name of existed CVAR from removed FMOD sound backend is used
Increased default size of stream buffer to 64 kB like it was in FMOD backend
This fixes the following compilation warnings:
src\sound\oalsound.cpp(1588): warning C4244: 'argument': conversion from 'unsigned int' to 'ALfloat', possible loss of data

Stopping a source in the middle of playback can causing undesirable "popping"
from a sudden change in amplitude. Setting the source gain to 0 gives OpenAL
the opportunity to ramp the source's output to 0, where it can be safely
stopped without causing a sudden change in amplitude.
This isn't supported with the OpenAL backend, and instead of trying to make a
workaround for it, a better approach would probably be to make a FileReader
implementation that handles URLs.
