Message:

Ticket #983: make native WMME the default audio device on Windows and Windows Mobile:

• increase default playback latency (PJMEDIA_SND_DEFAULT_PLAY_LATENCY) to 140ms for Win32 and 160ms for WM
• set default PJMEDIA_SOUND_BUFFER_COUNT to (PJMEDIA_SND_DEFAULT_PLAY_LATENCY+20)/20 rather than hardcoded 6
• disable PA from audiodev on Win32 and WM
