- Clean up symbol visibility.
- Don't force quit in signal handler, since we might double-free things.
- Disable reverb flag in modplug decoder. It's producing trash in some cases.
- Don't underflow array when parsing timidity config file.
- Fix read_config_file() not closing the file when there is an error.
- Honor the return code from recursive read_config_file() call.
- Reset some state on shutdown to prevent crash when reinitializing.
