Fixes sound system to work with archives (use VFS files instead of POSIX), fixes #1604. Improves error handling and logging, refs #1594. Allows sound to be disabled with -nosound/-quickstart runtime options or --without-audio build option, fixes #1609, #1614. Experimentally increases default buffer size to help prevent sound stoppages. This was SVN commit r12566.
