 1.5  12-May-2025  nat Add code to configure the Digitally Filtered Audio Chip.

This was the missing puzzle piece to audio recording on the Macintosh.

It is currently experimental and use caution when testing!

It should work on most machines expecpt the PowerBook 5xx and similar
due to the fact they configure the dafc via the power manager.
 1.4  09-Apr-2025  nat Move version identifiers to ascreg.h

No functional change intended.
 1.3  13-Jan-2025  riastradh mac68k/asc: Nix trailing whitespace.

No functional change intended.
 1.2  12-Jan-2025  nat Overhaul of ascaudio(4).

Simpler interrrupt function.
Volume control works properly on different variants of EASCs.
Alternate FIFOs identified for some EASCs.

Recording still does not work as yet as microphone audio needs to be routed
to the sound chip. However attempting to record should no longer cause a
lockup or panic.
 1.1  13-Mar-2024  nat branches: 1.1.2;
