decoder/vorbis: faster tag scanning with ov_test_callback()
using ov_test_callback with function CALLBACKS_STREAMONLY will cause scanning to stop after the comment field. ov_open (and ov_test) default to CALLBACKS_DEFAULT which scans the file structure causing a huge slowdown. The speed improvement is huge: It scanned my files around 10x faster This procedure has been recommended by monthy (main vorbis developer) and was said to be safe for scanning files.
