Always check for open and close events.
Send WM_APP message to thread to terminate it rather than TerminateThread.
Fix CreateThread/waveOutOpen race by waiting for background thread to
run before waveOutOpen is called.
Add more non-hardware supported formats.  There is a bug in wave
mapper GetPosition when multiple headers are used and this helps
trigger it.

FILEOPEN95_OnOpen assumes that each item in the filter list returns a
non-NULL pointer for CB_GETITEMDATA.

Allow some objects to have no parent device.
Tighten refcount tests and test refound decrement on Release.

unmarshaler routines of embedded complexes in complex struct and array
unmarshaling.

Fixes a regression caused by commit

Dobramysl.

set the number of pointers to a large default, so that NumberOfBuckets
doesn't end up less than zero.

rpcrt4: For full pointers the state consists of flags, so or new flags into the field instead of assigning.

The return value of all full pointer functions that return an int 
depends on the passed in query type being a flag in the state.

The current wave tests only use a single header for playback.  Tests
have been added to use multiple headers and to reuse them.  This is
how streaming applications and direct sound use the wave api.
