Author: Arthur Taylor <art@ified.ca>
Reason: The minimal possible MPEG file contains no headers or identification
other than the brief sync header. This header is only 3 bytes, and is quite
prone to false-positives. Particularly raw PCM can look like a sync header.
As such, move detection of 'naked' MPEG files in guess_file_type()
to the very last test. Give more weight to a sync header if it
follows an ID3 tag.
