Sometimes we may need to iterate over, or find an element in a read only (or read mostly) red-black tree, and in that case we don't need a mutable reference to the tree, which we'll however have to take to be able to use the current (mutable) cursor implementation. This patch adds a simple immutable cursor implementation to RBTree, which enables us to use an immutable tree reference. The existing (fully featured) cursor implementation is renamed to CursorMut, while retaining its functionality. The only existing user of the [mutable] cursor for RBTrees (binder) is updated to match the changes.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
