Stopping playback does not stop currently playing audio files

[sgreene570]

pthreads need to be killed when "stopping" the play back sequence even if the song is actually longer than a couple seconds. Long wav files will play until done once they start. This is a problem.

this is gonna be a little tricky to fix.
This section will need to be re-worked.

this is a big bet

I was looking into this and I found some interesting stuff in the manpages. It might not be so complex, unless I'm missing a detail, but it should be possible to stop the thread by referencing its ID.

Before returning, a successful call to pthread_create() stores the ID
of the new thread in the buffer pointed to by thread; this identifier is
used to refer to the thread in subsequent calls to other pthreads functions.

You might also just be able to keep track of the threads in the first place with an array and then pthread_canceling them accordingly. The issue then becomes that this would probably require some intense malloc action, since big sampleZone projects would have a lot of threads.

So I think I've found another clue that could turn into a solution. The thread starts, and is stopped by pressing space like I've been doing, but that's not what needs to stop. In playback.c there is a for loop that appears to control playback. It might be possible to have that function listen for a ' ' and return when it hears that. That should stop the audio.

I might have something resembling a solution in https://github.com/WillNilges/sampleZone/tree/will-threading
