* gtk/gtkfeatures.h.in: new file used as template for
* gtk/gtkfeatures.h: new file to define macros indicating newly
introduced features, such as GTK_HAVE_SIGNAL_INIT.
* gtk/gtksignal.c:
(gtk_signal_emitv_by_name):
(gtk_signal_emitv):
new functions to emit signals with an already provided parameter set.
(provided by Kenneth Albanowski <kjahds@kjahds.com>).
(gtk_signal_real_emit): prototype changes, so this functions always
gets its parameters and signal structure as arguments.
(gtk_signal_emit): provide the signal structure and parameter list for
gtk_signal_real_emit.
(gtk_signal_emit_by_name): likewise.
