gmmproc: _WRAP_VFUNC: Support the wrapping of slots.

	* tools/pm/WrapParser.pm (on_wrap_vfunc): Add support for parsing the
	additional 'slot_name', 'slot_callback', and 'no_slot_copy' options
	that do the same thing as the corresponding _WRAP_METHOD options (ie.
	specify the name of the C++ slot parameter, the name of the callback
	function and whether to use the original slot or a copy of it,
	respectively.  Also pass the options along to:
	(output_wrap_vfunc): Store the options in the C++ virtual function
	object so they can be tested for when converting the parameters and
	composing the _VFUNC* m4 macro calls.
	* tools/pm/Output.pm (output_wrap_vfunc_cc):
	- Append the additional 'slot_type', 'slot_name' and 'no_slot_copy'
	parameters to the _VFUNC_CC m4 macro invocation so that it can include
	code for the vfunc to copy the slot parameter and pass it on to the C
	function.
	- Also append the additional 'slot_type' and 'c_data_param_name' to
	the _VFUNC_PCC m4 macro so that it knows the slot type and the C
	gpointer parameter name that contains the slot so that the macro can
	generate code to extract the slot from the data parameter and pass the
	slot on to the C++ virtual function.
	(convert_args_c_to_cpp):
	- Rewritten so that it loops through the C++ parameters so that it is
	possible to re-order the parameters using the existing mapping
	functionality that allows parameters to be re-ordered for the
	_WRAP_[CREATE|CTOR|METHOD] macros.  Also re-written so that it knows
	how to deal with slot parameters.
	* tools/m4/vfunc.m4 (_VFUNC_PCC): Modified to accept the additional
	'slot_type' and 'c_data_param_name' arguments and to insert code to
	extract the slot from the C gpointer data parameter to be passed on
	to the C++ virtual function.
	(_VFUNC_CC): Modified to accept the additional 'slot_type',
	'slot_name' and 'no_slot_copy' arguments and to insert code to either
	copy the slot in a 'slot_copy' variable or set the variable to the
	actual slot (if it's so been specified) which is then passed on to the
	C function.
