The patch seems pretty huge but mainly are mechanical steps: - remove GObject declarations - do not inherit from GObject - add SPICE_CXX_GLIB_ALLOCATOR to avoid using C++ allocators - CLASS_init and CLASS_constructor code goes into C++ constructor - CLASS_dispose and CLASS_finalize code goes into C++ destructor - g_object_new is replaced by new operator - class members goes into virtual methods - class parameters became argument to constructor - use push-visibility.h and pop-visibility.h to limit visibility - temporary use XXX_CAST for old GObject casts, they will be replaced - g_object_get is replaced by accessors Signed-off-by: Frediano Ziglio <fziglio@redhat.com>
