Improved API library version API

[PortAudio-admin]

Issue created by @RossBencina

The current library version API is not useful enough to support clients that are compatible with multiple library versions. Ticket #172 covers removing structVersion fields (and links to discussion about why they aren't very usefull in practice).

Ross proposed a global version number API here, but it wasn't really discussed in detail
http://music.columbia.edu/pipermail/portaudio/2008-February/008332.html

void Pa_GetVersion( int *major, int *minor, int *point );

There is also a request to provide #defines in the header file (PA_LIBRARY_VERSION_MAJOR, etc) so that code can detect the version at compile time.

More discussion here:

programs shoudl check API version not implementation version)."

It's nice to have a single integer containing the version. Something like:

versionCode = (major<<16) + (minor<<8) + point

This seems to be fixed by recent commit: https://www.assembla.com/code/portaudio/subversion/changesets/1922#commit/comment:771023/line:9/path:portaudio/branches/versioning/src/common/pa_front.c

Also, SVN revision can be included with:

const char* paSvnRevision = "$Revision: $";

which will expand to f.i.

const char* paSvnRevision = "$Revision: 1922 $";

when committing it.
