Log message:
Replace audio(9) get_props() with duplex check in open() in partial duplex
drivers
Make drivers which do *not* adverise AUDIO_PROP_FULLDPLEX return ENXIO
in their open() if full-duplex mode was requested.
This way, sys/dev/audio.c:audio_open() will fail immediately rather than
later through the to-be-removed get_props() check.
This is the first round for drivers with logic in their get_props(), i.e.
those that only support full-duplex mode for specific hardware:
ess(4), gus(4), pas(4) and sb(4)
All of these are i386/GENERIC only and share code through
sys/dev/isa/{ad1848,sbdsp}{.c,var.h} which are not used by any other kernel.
i386/GENERIC.MP builds and boots with this diff.
