In OSS_RawOpenDevice, always retrieve the device format and store it 

in the OSS_DEVICE structure.
Modify our internal functions so that they can be told to still open
the device even if the device format is not an exact match.
In wodOpen return the actual device format if the WAVE_DIRECTSOUND
flag is set.
Fixes DirectSound on i810 soundcards (i.e. cards supporting only
48000x16x2).
