[gtk-vnc] Introduce pulse audio bridge for GVnc

commit 1814f6c54b8a5ee2e5daeb80a5b2d7fe5403250f
Author: Daniel P. Berrange <berrange redhat com>
Date:   Fri Dec 9 15:23:42 2011 +0000

    Introduce pulse audio bridge for GVnc
    
    Introduce a new library libgvncpulse-1.0.so which provides an
    implementation of VncAudio that uses Pulse Audio for output
    
    * Makefile.am, gvncpulse-1.0.pc.in: Add pkgconfig file for
      libgvncpulse
    * gtk-vnc.spec.in: Add gvncpulse & gvncpulse-devel sub-RPMS
    * src/Makefile.am, src/gvncpulse.h, src/libgvncpulse_sym.version
      Add gvncpulse-1.0 library
    * src/vncaudiopulse.c, src/vncaudiopulse.h: Pulse audio
      impl of VncAudio
    * vapi/Makefile.am: Build vala binding for pulse audio
