direct sound patches

[Robert Reif]

This patch adds a configuration option for setting
the hardware acceleration level just like the direct
sound control panel app.  Four levels are introduced:
Full, Standard, Basic, and Emulation. Only Emulation
or not Emulation are used now.  This is used to force
a direct sound capable sound device into emulation
(waveIn/Out) mode.  This is provided so direct sound
capture capable sound cards can be used while the
direct sound capture driver is not complete. Add this
line in the config file [dsound] section:
"HardwareAcceleration" = "Emulation"
to force emulation mode.

More work on the full duplex interface so the compile
warning is no longer generated.  Full duplex interface
is still stubbed out.

Moved full duplex mixer reset fix into wineoss driver
where it belongs.

Added some more locking fixes.

Capture and full duplex are now stable.
