tree-walk: learn get_tree_entry_follow_symlinks
Add a new function, get_tree_entry_follow_symlinks, to tree-walk.[ch]. The function is not yet used. It will be used to implement git cat-file --batch --follow-symlinks. The function locates an object by path, following symlinks in the repository. If the symlinks lead outside the repository, the function reports this to the caller.
