Makes libossaudio use sndio instead of the kernel mixer(4) interface.

Programs will see the device handled by sndiod (instead of the first one) and will always get access at least the sndiod master level control. If present, hardware master input and output volumes are exposed as well. feedback from landry and sthen, "do it" deraadt

When system calls indicate an error they return -1, not some arbitrary

value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

remove a misleading comment; ok ratchov@

Make SNDCLT_DSP_* ioctls return ENOTTY, and remove the corresponding

code. No ABI change. ok armani@, guenther@, sthen@

rename define to reflect current operating system, as in sys/compat

First pass at removing clauses 3 and 4 from NetBSD licenses.

Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@

simplify SNDCTL_DSP_SETTRIGGER

- don't mess with the operational mode. that was primarily to be able to set record|play mode for full-duplex, which isn't needed any more. - don't set pause=1. this ioctl isn't supposed to be used for stopping streams. suggestions, ok ratchov

this is the recording source. rename 'source' to 'recsource' and be

2007-11-12T05:43:59Z

sure to only use 'record.source' instead of possibly 'inputs.source'.

a single OSS ioctl, return the return value and errno from from AUDIO_SETINFO if there was an error, since it's more informative than the return value and errno from AUDIO_GETINFO. also, don't bail if AUDIO_SETINFO fails, because OSS ioctls should return the current value of the parameter they are setting, even if there was an error. - avoid a possible (though highly unlikely) divide by zero in SNDCTL_DSP_GET[IO]SPACE. ok ratchov@
