[girepository] Split out GIBaseInfo

Split out GIBaseInfo to a separate source file.
Move out definitions to gibaseinfo.h/gitypelib.h/gitypes.h
and girepository-private.h

Install gibaseinfo.h/gitypelib.h and gitypes.h as well, but
require users to include girepository.h

+ * @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>
+ *

- * 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>
- *
