Add new arcofi(4) audio driver for NetBSD/hp300, ported from OpenBSD.
The arcofi(4) is a driver for the HP "Audio1" device
(Siemens PSB 2160 "ARCOFI" phone quality audio chip)
found on the HP9000/425e and HP9000/{705,710,745,747} models
(but only hp300 attachment is ported for now).
The chip supports 8-bit mono 8kHz U-law, A-law and
16-bit mono slinear_be formats.
The old HP9000/425e playing tunes with this new arcofi(4) audio driver
was also demonstrated at Open Source Conference 2014 Shimane.
Add a man page for arcofi(4) driver.  From OpenBSD.
Fix date.
