glib/ginfo.c
Johan Dahlin 7e2e379388 [girepository] Use g_slice 
Use g_slice to allocate instead of g_new(x, 1); It uses a memory
pool internally and should be faster, especially for GBaseInfo/GRealInfo,
structs which are tiny.

* SECTION:gibaseinfo
* @Short_description: Base struct for all GTypelib structs
* @Title: GIBaseInfo
*
* GIBaseInfo is the common base struct of all other *Info structs
* accessible through the #GIRepository API.
* All other structs can be casted to a #GIBaseInfo, for instance:
* <example>
* <title>Casting a #GIFunctionInfo to #GIBaseInfo</title>
* <programlisting>
* GIFunctionInfo *function_info = ...;
* GIBaseInfo *info = (GIBaseInfo*)function_info;
* </programlisting>
* </example>
* Most #GIRepository APIs returning a #GIBaseInfo is actually creating a new struct, in other
* words, g_base_info_unref() has to be called when done accessing the data.
* GIBaseInfos are normally accessed by calling either
* g_irepository_find_by_name(), g_irepository_find_by_gtype() or g_irepository_get_info().
*
* <example>
* <title>Getting the Button of the Gtk typelib</title>
* <programlisting>
* GIBaseInfo *button_info = g_irepository_find_by_name(NULL, "Gtk", "Button");
* ... use button_info ...
* g_base_info_unref(button_info);
* </programlisting>
* </example>
*
