Subject: [PATCH] quit: Destroy all mixers, then all audiodecoders, then all
 audios.

Mixers first, so callbacks stop before destroying anything else, AudioDecoders
next because they use MIX_Audio internally, which are then destroyed last,
when the list no longer contains the ones that any AudioDecoders were using.

Reference Issue #861.
