Demodulating the 14.2 Hz Stardust carrier: software update and benchmark results.

The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record.
Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time.

Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser.

Compiled cleanly under gcc -O2 on my Slackware box. The adaptive Costas loop is rock solid even on my scratched US copy.

Netscape 1.1 crashes when loading large preformatted text. Stick to rn or tin!
