`delete_fn`::
Pointer to the function that should handle the delete routines for the `key` pointer.
`update_fn`::
Pointer to the function that is called when the implementation performs an update of an `key` pointer. +
The function gets the following information passed in order: old pointer, new pointer.
NOTE: You may only need this if you store the data in another structure and has to keep it synchronized with the RB-tree.
`cmp_fn`::
Pointer to the function that is used to compare two `key` pointers. +
Shall return a value greater than zero if 'ptr1' > 'ptr2', a value less than zero if 'ptr1' < 'ptr2' and zero if 'ptr1' == 'ptr2'.

`rbtree_insert()`::
Creates and inserts a new node in the tree. +
If provided, calls `rbtree->update_fn` and `rbtree->delete_fn` if a node should be updated. +
If provided, calls `rbtree->delete_fn` if a node should be updated. +
Returns nonzero if a new node was inserted or updated, zero otherwise.
NOTE: The memory pointed to by the 'key' pointer is *not* copied so you must ensure that it has a infinite lifetime.
