audio: Add winaudio as an alternative audio backend for Windows

QEMU's default audio backend for Windows, winwave, does not work well
with the goldfish audio device when audio input is enabled. The classic
Android emulator does not use winwave, but introduces its own Windows
audio backend called winaudio. This patch adapts winaudio for QEMU 2.x
and makes it available as an alternative audio backend for Windows.
