More general code cleanup for readability.

A few more parameter validation checks. Return DS_OK rather than 0 in a number of functions. Fixed primary buffer ref count bug in CreateSoundBuffer(). Handle 1-3 byte sound fragments that would cause buffer overruns. Clear primary buffer with a neutral value instead of always 0 (because 128 is neutral for 8-bit sound). Fix bug with mixing 8-bit sound into the primary buffer. Broke out the main block in DSOUND_thread() to another function for readability. Handle "no audio" and "audio busy" cases properly when initializing dsound. Rename DllCanUnloadNow() to DSOUND_DllCanUnloadNow().
