Subject: [PATCH] add gnulib files
Reference: https://gitlab.com/libidn/gnulib-mirror/-/tree/master/lib
Conflict: NA
files(*.c,*.h) below from gnulib, but no commit id in gnutls repository.
fix CVE-2024-28835 need those files.
Makefile.am and Makefile.in generated by automake.

+/* gl_list is an abstract list data type. It can contain any number of
+ objects ('void *' or 'const void *' pointers) in any given order.
+ Duplicates are allowed, but can optionally be forbidden.
+
+ There are several implementations of this list datatype, optimized for
+ different operations or for memory. You can start using the simplest list
+ implementation, GL_ARRAY_LIST, and switch to a different implementation
+ later, when you realize which operations are performed the most frequently.
+ The API of the different implementations is exactly the same; when
+ switching to a different implementation, you only have to change the
+ gl_list_create call.
+
+ The implementations are:
+ GL_ARRAY_LIST a growable array
+ GL_CARRAY_LIST a growable circular array
+ GL_LINKED_LIST a linked list
+ GL_AVLTREE_LIST a binary tree (AVL tree)
+ GL_RBTREE_LIST a binary tree (red-black tree)
+ GL_LINKEDHASH_LIST a hash table with a linked list
+ GL_AVLTREEHASH_LIST a hash table with a binary tree (AVL tree)
