Return value is analog to what the ALSA and OSS driver are doing.

Some HeapFree's are hidden behind macros. Found by smatch.

Ues pipe sync code from OSS/ALSA rather than windows events.

Fixes WIDM_GETDEVCAPS and WODM_GETDEVCAPS.
Call Unicode functions instead of their Ansi equivalent when possible.

Nameless struct fix for dsound/propset.c to compile on both windows
and wine.

redundant.

32 bit low level drivers now use a Unicode interface (used to be ANSI):
- Send the *_GETDEVCAPS messages in unicode format from the
  *GetDevCapsW function and call the *GetDevCapsW from their respective
  Ansi versions.
- Modify all low level drivers to correctly process the *_GETDEVCAPS
  messages as unicode.
- *_GETDEVCAPS messages are now mapped from/to unicode for 16 bit code.
- Removed all SoundBlaster naming oldies.
Better use of some unicode functions (instead of Ansi) in winmm.

dsound.dll (like in 2k/xp).

the requested MMTIME format. This function should be identical in all
drivers.
Remove the corresponding code from wodGetPosition() and
widGetPosition() and use bytes_to_mmtime() instead.
bytes_to_mmtime() uses no floating-point arithmetic to compute
TIME_SMPTE and no longer uses round(). It should have no integer
overflows either.

Fixes the corresponding winmm conformance test.

it can happen in perfectly normal conditions.

More accurate ms calculation.

Fix SMPTE time.

Add support for wave interface message where missing.
