changed collect_format, collect_value() and lcopy_format, lcopy_value() in

        * gtype.[hc]: changed collect_format, collect_value() and lcopy_format,
        lcopy_value() in the GTypeValueTable. the collect functions are now
        called only once per value, collect_format/lcopy_format are strings
        that enlist all necessary GTypeCValues to be varargs-collected.

        * gvalue.h: ranamed STATIC_TAG to G_VALUE_NOCOPY_CONTENTS to indicate that
        a value shouldn't copy its contents.

        * gvaluecollector.h: changed G_VALUE_COLLECT() and G_VALUE_LCOPY()
        macros to carry an additional argument (flags) that can be used
        to pass G_VALUE_NOCOPY_CONTENTS along to the collection functions.

        * *.c: adapted collect_value() and lcopy_value() functions to the new
        prototypes, support G_VALUE_NOCOPY_CONTENTS where apropriate.

        * gsignal.[hc]: introduced a G_SIGNAL_TYPE_STATIC_SCOPE flag that can
        be passed along (ORed) with the parameter types, indicating that the
        emission arguments are to be considered static for the scope of the
        emission. should be used with care and only if the caller knows that
        a parameter cannot be destroyed/freed from signal handlers connected
        to an emission.
