Reorganised the source tree. We now have src/ with a couple of subdirs:
* daemon/ - Contains the files specific to the polypaudio daemon. * modules/ - All loadable modules. * polyp/ - Files that are part of the public, application interface or are only used in libpolyp. * polypcore/ - All other shared files. * tests/ - Test programs. * utils/ - Utility programs. git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@487 fefdeb5f-60dc-0310-8127-8f9354f1896f
