ae997346b5 Add factor_denom, a denominator of factor, 
in 'struct audio_param' for vs0 on x68k.

{hw,user}_bytes_per_sample is changed to {hw,user}_bits_per_sample
to handle 4bit/sampling.

1339e88a86 Add a new optional method, dev_ioctl, to the audio hardware driver interface. 
It is called when an unrecognized ioctl() is performed on a device,
thus allowing ioctl()s that frob the hardware driver (like loading
microcode).

8d9290c427 Allow 24 and 32bit linear audio. 
Actually, the silence filler can do any multiple of 8 bits now, but I didn't
allow the parameter check to accept more than 32 bit to avoid confusion
of drivers that fail to check the parameters themselves thoroughly.
This should be changed later.

577ac6e31c Remove the line in audio_open which zeroes sc_[pr]r.blksize. 
Because zeroing them causes zero division panic with devices which don't
support 8kHz mulaw, and the effect of this line was to force calling
audio_calcwater even when unnecessary.

5b7fb2728a Back out changes from 1.124 since the additions of *ports.master=-1 wasn't 
documented as to why it was added in and it breaks the ability to set the
gain on playback. A longer term fix to set these correctly should be done but
none of the drivers today are doing this and not being able to set the playback
volume otherwise is a bit silly.

4f3fc10939 Fix PR#2060 (add AUDIO_PERROR ioctl to query # of playback drops), also 
fix semantics of AUDIO_WERROR (now returns a count).

Also repair audio driver back to "real-time mode" where user must
provide data quickly enough for real time audio or silence is played
until user catches up.  Add optional "play all" mode (additional bit in
mode field) to play all samples provided, with silence when needed to
avoid buffer underrun.
