	* glib.h:
	* garray.h:
	(g_array_remove_index): new function for removing an entry from an
	array while preserving the order
	(g_array_remove_index_fast): new function for removing an entry
	from an array. the order might be distorted
	(g_ptr_array_remove_index_fast, g_ptr_array_remove_fast): new
	functions; working similiar to the above. (they have the semantic
	of the old g_ptr_array_remove[_index] functions)
	(g_ptr_array_remove_index, g_ptr_array_remove): new semantic. now
	the order of the elements in the array is not changed
	(g_byte_array_remove_index, g_byte_array_remove_index_fast): new
	functions; byte_array wrapper for g_array_remove_index[_fast]
