selinux: add FILE__WATCH_MOUNTNS
Watching mount namespaces for changes (mount, umount, move mount) was added
by previous patches.

This patch adds the file/watch_mountns permission that can be applied to
nsfs files (/proc/$$/ns/mnt), making it possible to allow or deny watching
a particular namespace for 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.
