Update to the latest PortAudio (PA) and fix PA issues on MacOS X Snow Leopard (thanks Saul Ibarra Corretge for the fix)

Some errors have been reported on building/running PJSIP on MacOS X Snow Leopard:

In r3042:

• updated PA to the latest version (revision 1438)

Note that this seems to have broken compilation with Visual Studio 6, which would generate error like this:

pa_win_ds.c
c:\users\benny\project\pjproject\third_party\portaudio\src\hostapi\dsound\pa_win_ds.c(746) : error C2065: 'DSSPEAKER_5POINT1' : undeclared identifier
c:\users\benny\project\pjproject\third_party\portaudio\src\hostapi\dsound\pa_win_ds.c(746) : error C2051: case expression not constant
c:\users\benny\project\pjproject\third_party\portaudio\src\hostapi\dsound\pa_win_ds.c(747) : error C2065: 'DSSPEAKER_7POINT1' : undeclared identifier
c:\users\benny\project\pjproject\third_party\portaudio\src\hostapi\dsound\pa_win_ds.c(747) : error C2051: case expression not constant
c:\users\benny\project\pjproject\third_party\portaudio\src\hostapi\dsound\pa_win_ds.c(748) : error C2065: 'DSSPEAKER_7POINT1_SURROUND' : undeclared identifier
c:\users\benny\project\pjproject\third_party\portaudio\src\hostapi\dsound\pa_win_ds.c(748) : error C2051: case expression not constant

This is because Visual Studio 6 has its own (very old) Direct X SDK.

The solution is to use newer DXSDK, and put the DXSDK Include and Library patch before Visual Studio 6 Include and Library paths in the directory order.

In r3050:

• use PortAudio? revision 1433 instead, since PA revision 1434 introduced dependency to newer DirectX SDK (DXSDK v9 2002/2004 edition fails to compile PA)
