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().

Added names for some undocumented exports.

Fixed off-by-one checks for buffer wrap.
Increment ref count for primary buffer in CreateSoundBuffer().
Added DSBPN_OFFSETSTOP support to position notification code.
Lots of minor parameter validation checks.
Stubs for: IDirectSound_initialize(), IDirectSound_Compact(),
and IDirectSound_GetSpeakerConfig().
Fixed freq shifting with 16-bit data problem, fixed 8bit<->16bit
conversion.
Lots of thread locking for DirectSound buffers.
Dealloc primary buffer when dsound is deallocated.

configure option.

One missing break in SPI_GETDRAGFULLWINDOW.

- more versatile support of surfaces / better surface description support.

New functions ParseField, Get/SetInstanceExplorer(), PathIsUNC, PathIsRelative.
Stubs SHWaitForFileToOpen, PathFindOnPath.

Fixed support for RMID files in MIDI_mciOpen.
Fixed bug for playing MIDI files with tempo changes. Sound output is
now correct, but length of tracks (and therefore of whole file) is not
correct.
Changed error values (INTERNAL => INVALID_FILE) when file cannot be read.
