Log Message:
Add haud(4), a driver for audio playback using Iris Indigo's
onboard DSP ("Hollywood Audio"). The same hardware is also
present on Personal Iris 4D/3x machines, split across the
mainboard and an optional "Magnum Audio" card (untested).

The DSP requires firmware, so this driver leverages IRIX's
hdsp.lod. Since that's proprietary, it's left up to the user
to install it from an existing IRIX system or its installation
media. See forthcoming haud(4) manpage for details.
