Workaround for broken OSS_GETVERSION on FreeBSD, part two

Turns out on those versions of FreeBSD (>= 7.x) that know OSS_GETVERSION
the ioctl doesn't actually work yet (except in the Linuxolator), so if
building on FreeBSD assume the sound drivers are new enough if the ioctl...

oss: fix fragment setting

Previous patch introduced subtle regression, in cases when
OSS_GETVERSION fails the code wasn't falling back to
SNDCTL_DSP_SETFRAGMENT.

Additional argument (whether to try poll mode) is only passed with
VOICE_ENABLE command.

Thanks to Markus Armbruster for noticing the potential breakage.

audio: internal API change

pcm_ops.run_out now takes number of live samples (which will be always
greater than zero) as a second argument, every driver was calling
audio_pcm_hw_get_live_out anyway with exception of fmod which used
audio_pcm_hw_get_live_out2 for no good reason....

Check the returned audio_buf_info fields

fragstotal (reported by Dave Scott), this results in an audio_calloc
failing the audio_bug check and another ominous error message. Fail
early and blame the system....
