By taking alternative code-paths in WdmAud and bypassing Sysaudio.
This relies on the patch 0.4.15-dev-765-g
b8e936a57b
It fixes the following bugs/regressions:
-CORE-13202 Unhandled exception from wdmaud.drv when recording sound in Scratch 1.4 leads to app-crash
-CORE-13488 A deadlock in "DiabloII" character selection screen and "The Lion King II"
-CORE-8726/CORE-9986/CORE-16564 AC97 driver is now working in the same session where driver was installed, no reboot-orgies needed anymore
-CORE-9981 almost 100% fixed, DosBox + Commander Keen6 properly plays music instead of garbled output,
same improvement for ScummVM 2.0 with Monkey Island 2
The playback is not yet *entirely* perfect, still a few hiccups now and then, but
by orders of magnitude better than before.
Remove misuse of multithreading and use NtDeviceIoContol with completion apc
callback instead (mirrors usage of WriteFileEx in WdmAudCommitWaveBufferByLegacy).
This fixes a crash caused by race condition. Code was simulating completion
callback using a thread, this resulted in single threaded code being executed
simultaneously by multiple threads.

There is no need to compile our DLLs as shared libraries since we are
managing symbols exports and imports through spec files.
On my system, this reduces the configure-time by a factor of two.
