This patch adds a VncInput base class which VncServer inherits from. Another class can implement the same interface and be used instead of the VncServer, for example a class that replays Vnc traffic. --HG-- rename : src/base/vnc/VncServer.py => src/base/vnc/Vnc.py rename : src/base/vnc/vncserver.cc => src/base/vnc/vncinput.cc rename : src/base/vnc/vncserver.hh => src/base/vnc/vncinput.hh
